Mark, the overseas scenic spot manager, almost messed up the reception when he used the traditional one-to-many wireless guide device for the first time - one transmitter connected to 20 receivers, but after adjusting it for half an hour according to the manual, it still couldn't be connected. Finally, the guide from the neighboring team's sound also interfered. When he wanted to switch to Japanese for Japanese tourists, he couldn't find the switch key in the menu. In the end, he could only have the tourists listen to English around, resulting in a chaotic and awkward scene. In fact, not only Mark, but many overseas users who were exposed to this one-to-many device for the first time would be stopped by "complex connections, interference, and difficulty in adjusting for multiple languages", feeling that "it's so troublesome, it's better not to use at all".
    As the core product of Hefei Huima Information Technology Co., Ltd., which has been deeply involved in the guided tour industry for 15 years, Yingmi's wireless guide device for one-to-many connections has avoided the pitfall of "complex use" from the very beginning - it engraves "fast connection, simple adjustment, and easy management" into every step of operation. Even for overseas users who are using it for the first time, they can master it in just 5 minutes. It has become the choice of Huawei, the British Museum, and the SCO, and has made 4,000+ users worldwide feel "useful and convenient". Yingmi's confidence lies in the details that "without professional skills, it can also be easily used well for one-to-many connections" - it is not a "device that requires training to use", but a practical tool for overseas guided tours that "can be used immediately after picking it up".

I. Overseas Use: One-to-Many Mode, Avoid These 4 "Use Pitfalls" First

Many overseas users think that "one-to-many mode is troublesome to use", but in fact, they have fallen into the traps of traditional devices. These issues have turned the simple "using the device" into a "troubleshooting the device":

1. Connection is complex, and it takes a long time to connect

Traditional one-to-many mode requires manual pairing of channels. The transmitter selects the frequency, the receiver searches for the frequency, and repeated confirmation is needed for "whether there is a connection error". When Mark led the group, "the transmitter pressed the channel button 10 times, but the receiver still didn't respond. Finally, it was discovered that the reset button needed to be pressed for a long time first. The small print in the manual said this, who could notice?" ； Worse still, when multiple teams are working simultaneously, "one has to remember the channel numbers of each team to avoid confusion. One gets so nervous that one's palms start to sweat."

2. Interference occurs frequently, and the channel adjustment doesn't work for a long time

Traditional equipment has weak anti-interference capabilities. Even if they are slightly closer, interference occurs. When a certain enterprise received a delegation of suppliers, "we were talking about 'chip testing', but suddenly the 'sales policy' of the neighboring team popped up. A German supplier frowned and asked, 'Are you talking about technology or selling goods?'"; adjusting the channel didn't help either. "We changed three channels, but the interference persisted. Finally, we had to let the teams go separately, and the itinerary was all messed up."

3. Switching between multiple languages is difficult, and tourists wait for a long time

The overseas teams have diverse languages. Traditional equipment either has a limited number of languages or requires looking for a tour guide to switch. When Martin led a study tour group, "a Japanese tourist wanted to switch to Japanese. I spent 5 minutes flipping through the menu to find it. The Swedish tourist behind asked, 'When will we get to our language?'"; worse still, after switching, the equipment had to be restarted, "for those 2 minutes, the tourists were all looking around, which was extremely embarrassing."

4. Batch management is chaotic, and collecting equipment is like a battle

When leading a group of several dozen people, collecting equipment, charging, and disinfecting take an hour. Traditional equipment requires plugging in each device one by one for charging, "50 devices spread on the ground, the power strip was stacked 3 layers high. We had to get up and change batches at midnight." When storing, there were no labels, "it was impossible to distinguish which receiver corresponded to which team. We could only turn on all the devices and test them, which was so noisy that the hotel filed a complaint."

II. How to use Yingmi One-to-Many? 5 Easy Steps to Get Started

Yingmi One-to-Many doesn't require "professional operation". All steps are centered around "simplicity". Even overseas users without prior experience can follow along without making mistakes:

1. Opening the box and preparation: Take a look at the equipment, don't panic

In the Yingmi One-to-Many package, there are only 3 core devices. Don't worry about a bunch of parts:
Transmitter (handheld model E8-T, chest-worn model R8): Used by the presenter, with a microphone, capable of speaking and playing pre-recorded audio; the power button is on the top, press and hold for 3 seconds to turn on, the screen lights up and it's ready;
Receiver (earpiece/handheld): Used by tourists, the earpiece model weighs only 16 grams, comfortable to wear for a long time; there's no need to worry about the power button, it will automatically search for the signal;
Batch charging box (36-bit/48-bit): Used when receiving the equipment, no need to plug in, just put it in and it starts charging and disinfecting.
When overseas users receive the package, they first check the battery level (the screen of the transmitter shows the battery level, and the receiver presses the power button to see the light, a green light indicates full charge), pre-recorded explanations (connect the computer to upload audio, or use the mobile app to upload, supports MP3/WAV formats), and they're ready in 5 minutes.

2. Quick connection: 1-key pairing, no need for manual adjustment

Yingmi's most convenient feature is "automatic connection", no need to remember channels, no need to repeatedly press:
Transmitter settings: Long press the power button, press the "SET" button to select "team mode", the screen will display the current channel (such as CH-08), no need to change, the system will automatically allocate a strong anti-interference channel; to play pre-recorded audio, press the "FUN" button to select the file, then press the play button;
Receiver pairing: When tourists receive the receiver, long press the power button, it will automatically search for the signal from nearby transmitters, within 10 seconds it can connect, the screen shows "Connected to CH-08"; even if multiple teams are operating simultaneously, 200 independent channels do not interfere with each other, "We use CH-08, the next door uses CH-15, even if they are close, there will be no interference";
Temporary addition of equipment: If someone is late halfway, the new receiver can connect automatically, no need to restart the transmitter, Martin tried "adding 5 transmitters temporarily, fully connected automatically, not a minute was lost".

3. Multi-language settings: 1-key switch, customizable

The most concerned "multi-language" for overseas users is also simple to operate by tourists themselves:
Standard language switching: Press the "LANG" button on the receiver, the screen shows the language icon (English is EN, Japanese is JP, Arabic is AR), press the up and down keys to select, press "OK" to confirm, no need to look for a guide;
Special language customization: Contact Yingmi 3 days in advance, provide language requirements (such as Swedish, Portuguese), there will be a native speaker recording, and it will be uploaded to the device; Martin led a Swedish tour group, "48 hours in advance, the Swedish language was set, tourists could find it by pressing 'LANG', and they said 'The pronunciation is much more accurate than the translation software'".
Dual language synchronization: The transmitter supports "the presenter speaks Chinese, the receiver plays English" dual-speaking mode, press the "dual speaking" button, the presenter speaks normally, tourists listen to the translation, suitable for mixed language groups.

4. Scenario-based usage: Different occasions, use this way more smoothly

Yingmi One-to-Many can adapt to common tour guide scenarios in overseas areas, no need to change settings, just adjust according to the scenario:

(1) Outdoor scenic spots: Automatic sensing, no need to manually play

When visiting outdoor scenic spots like Gulangyu or Longhu Mountain, there's no need for a guide to keep pressing the play button:
Pre-bury RFID transmitters at the scenic spots (diameter 3 cm, can be buried behind green plants or signs), the sensing range is 1-35 meters;
Tourists wear the receiver and walk into the range, the automatic trigger of the explanation occurs, for example, at Dayangyuan it plays "Zheng Chenggong History", at Sushizhan Garden it plays "Piano Culture";
The signal can be transmitted 200 meters, in valleys and on the coast it can be stably connected, "At the viewing platform of the hanging coffins in Longhu Mountain, the wind is strong, but the equipment still triggers on time".

(2) Enterprise Workshop: Dual Explanation + Noise Reduction, Hear the Details Clearly

When receiving visits from suppliers in noisy scenarios like those at Huawei factories, the focus is on "noise reduction + dual explanations":
Turn on the "Noise Reduction Mode" (press the "NOISE" button), and the embedded SOC technology can filter out 90% of the machine noise;
The technical guide uses the main transmitter to explain "chip detection process", while the business guide uses the secondary transmitter to supplement "European market applications". Tourists can switch to listen without having to walk back and forth;
Set the receiver volume to 50%, and it's sufficient. "The workshop machine sounds are loud, but at 50% it's clearer than the traditional 100% equipment";

(3) Museum Exhibition Hall: Zone-based Explanation, No Interference

When visiting large museums like the British Museum or Suzhou Museum with multiple exhibition areas, use the "Zone Mode":
Install NFC tags (attached to the display cases) in each area. Tourists can lightly touch the tag with the receiver to trigger the corresponding explanation. For example, touching the "Ruoyao" tag plays the history of Ruoyao;
When multiple teams are working simultaneously, select "Zone Channel" (press the "AREA" button to select the corresponding area number). Different areas do not interfere with each other;
It can also play pre-recorded audio. When the guide is tired, press the "PLAY" button, and the device will speak by itself, "After visiting 6 exhibition areas, I only supplemented 2 details. It's much easier!".

5. Batch Management: Collecting Devices, Charging, Disinfection, One Step Done

With large groups, no longer need to "collect devices for half an hour". Yingmi's management tools help save time:
Quick device collection: Let tourists put the receivers in the slot of the charging box. No need to plug in the power cord. Contact-based charging. Put it in and it shows "Charging in progress";
Automatic disinfection: UV disinfection starts simultaneously during charging. 30 minutes can kill 99% of bacteria (such as Escherichia coli). Overseas tourists can use it with confidence, no need for manual wiping;
View device status: Log in to Yingmi's backend on your phone and you can see the battery level and connection status of each device. "Knowing that there are 10 devices still not returned, I go to the exit of the scenic area and wait, instead of searching the entire scenic area";
Easy storage: The charging box has wheels and can be pushed around. After collection, directly push it to the warehouse and don't move it around.

III. Overseas Scenario Testing: This Way, Efficiency Doubles

Yingmi's "easy-to-use" feature is not just theoretical; it is proven by overseas users in various scenarios. Every smooth usage session reveals details:

1. Huawei Dubai Supplier Group: 3 steps to use the dual-talk mode well

Huawei received a 100-person German supplier group and used Yingmi E8 for one-to-many communication:
Step 1: Turn on the transmitter, press "SET" to select "dual-talk mode", and connect the main transmitter to the technical guide and the secondary transmitter to the business guide;
Step 2: Distribute the receivers to the suppliers, turn them on and automatically connect to the signal. German tourists press "LANG" to switch to German;
Step 3: The technical guide explains "chip detection with an error of 0.01 millimeters", and the business guide adds "European order policies". The suppliers can switch to listen without separating the group.
The receptionist said, "Previously, with traditional equipment, it took 2 hours to bring 10 groups, but now it's done in 1 hour. The suppliers also said, 'The sound is clear and the switching is convenient.'"

2. Xiamen Gulangyu Scenic Area: Automatic sensing, tourists use themselves

For 10 scattered groups during the peak season at Gulangyu, Xiamen used Yingmi i7 one-to-many + Z50 self-service rental cabinet:
Step 1: Install RFID transmitters in Sunlight Rock and Suzhou Garden in the scenic area, and pre-upload many language explanations;
Step 2: Tourists scan the QR code to rent the receiver, turn it on and automatically connect to the signal. When they reach the scenic spot, it automatically plays the explanation;
Step 3: When the tourists return the equipment, put it in the rental cabinet, which automatically charges and disinfects. The next group of tourists can directly use it.
The scenic area operation manager said, "Previously, 10 groups required 5 staff to manage the equipment. Now, with just 1 person, it's done in 1 hour. Tourists can operate themselves, and the complaint rate has dropped by 80%."

3. British Museum Special Exhibition: Zone-based Use, No Interference

For the "Chinese Song Dynasty Porcelain Special Exhibition" at the British Museum, with 8 teams operating simultaneously, Yingmi MC200 was used for one-to-many communication:
Step 1: Set NFC tags in each exhibition area, and select the exhibition area number (1-8) on the transmitter;
Step 2: Tourists use the receiver to touch the tag, triggering the corresponding explanation, and can switch between English, French, and Arabic with one click;
Step 3: When returning the equipment, use the 48-bit charging box, which can be fully charged and disinfected within 10 minutes.
The guide department's Jones said, "Previously, there were daily complaints about interference. Now, there are no complaints at all. The tour guides don't have to repeatedly adjust the channel, and they can focus on explaining the culture."
