Frequently Asked Questions - UH36 Yealink

How do I connect the Yealink UH36 to my computer?

Plug the USB Type-A connector into an available USB port on your computer. The headset will be automatically detected and installed as a USB audio device. No additional drivers are needed for most operating systems like Windows, macOS, and Linux.

How do I mute or unmute the microphone?

Press the mute button on the inline control module. The mute LED indicator will turn red to indicate mute is active. Press again to unmute, and the red light will turn off.

Can I adjust the volume?

Yes, use the volume up/down buttons on the inline control module to adjust the speaker volume. Some systems also allow volume adjustment via the audio settings on your computer.

Is the UH36 compatible with Mac or Linux?

Absolutely. The UH36 is a USB audio device and works with macOS and Linux without additional drivers. Simply plug it in and select it as the audio input/output device in your system preferences.

How do I clean the headset?

Use a soft, dry cloth to wipe the ear cushions, headband, and microphone. Do not use any liquids or cleaning solvents. If necessary, gently remove the ear cushions and clean them separately with a damp cloth, then air dry before reattaching.

Can I replace the ear cushions?

Yes, the ear cushions are removable and replaceable. They are attached to the ear cups with a snap-fit design. Pull gently to remove, and press a new cushion onto the ear cup until it clicks into place. Replacement cushions are available from Yealink or authorized resellers.

What do the LED indicators mean?

There are two LED indicators on the inline control module: a red LED indicates the microphone is muted, and a blue LED indicates an active call (when used with a compatible phone system). The blue LED may flash during incoming calls.

Why is there no sound coming from the headset?

First, check the USB connection and ensure the headset is selected as the default audio device in your system settings. Verify the volume is turned up using the inline buttons. If using a softphone, check the application's audio settings. Restarting your computer may also resolve driver issues.

Will the UH36 work with my Yealink IP phone?

Yes, the UH36 is designed for seamless integration with Yealink IP phones that have a USB port. Simply plug the headset into the phone's USB port, and the phone will recognize it for both audio and call control (answer/end, mute). Refer to your phone's user manual for specific setup.

What is the warranty period for the UH36?

The Yealink UH36 comes with a 2-year limited warranty against defects in materials and workmanship. For warranty service, contact Yealink or your point of purchase. Retain your proof of purchase.

In the normal official environment, there are several softphones using at the same time.

And there is only one audio channel could take the call, so there is a call priority when there are several calls from different

softphones. For example, Teams,3CX, Bria, Webex, etc.

Here is the normal behavior when there are several calls from different softphones.

1. Build up a Teams call first->3CX call incoming->Pick up the call->3CX and Teams will both set to hold status
2. Build up a 3CX call first->Teams call incoming->Pick up the call->Teams will take the call, and 3CX will set to hold status.

• When you connect with 2 devices simultaneously with a multipoint connection, depending on the connected device, the device may keep sending the silent signal even if the playback of the music or video is stopped. In this case, the headset remains connected to the device, and the connection may not be changed to another device. If the sound from the second device cannot be heard after the playback is stopped on the first device, operate in the following order and check whether the situation has improved.

- Stop the playback of the application on the first device.

Depending on the connected device, the volume of the device and the headset may or may not be synced. If the volume on a device is not synced to the volume on the headset, it will not be possible to use the device to turn up the volume on the headset once the volume is turned down on the headset. In that case, turn up the volume of both the headset and the connected device.

Low sound quality, or noise sound can be heard Low sound quality, or noise sound can be heard

• Turn down the volume of the connected device if it is too loud.
• Some devices that emit ultrasonic sound waves designed to repel rodents may occasionally be installed at the entrances of commercial facilities or subway stations. Near such devices, the ultrasonic sound waves may cause noise or unusual sounds to be heard from the headset. Leave the place where the noise or unusual sound is heard. Or turn off the noise canceling mode from the Yealink USB Connect software.
• If the headset connects to the previously connected Bluetooth device, the headset may only establish the HFP/HSP Bluetooth connection when it is turned on. Use the connected device to connect via an A2DP Bluetooth connection.
• When listening to music from a PC on the headset, the sound quality may be poor (e.g., difficult to hear the callee voice, etc.) for the first few seconds after a connection is established. This is due to the PC specifications (priority on stable connection at the start of transmission and then switches to priority on sound quality several seconds later) and is not a headset malfunction.

Sound skips frequentlySound skips frequently

• When there is an obstacle, such as metal or a wall, between the headset and the Bluetooth device
• In places with wireless LAN, where a microwave oven is used, electromagnetic waves are generated, etc.
• If you are enjoying music with your smartphone, the situation may be improved by closing unnecessary apps or restarting your smartphone. If you are enjoying music with your computer, close unnecessary applications or windows and restart the computer.
