General Information:

– The receiver operates in the UHF band. The operating range is approximately 200m in open spaces.

– Dimensions: 72 x 45 x 13 mm, weight: 40 g.

– Use the rechargeable battery continuously for approximately 45 hours. The display shows the receiver’s battery capacity. Check the battery level and recharge if necessary.

– The receiver comes with a lanyard and a 3.5 mm earphone. The device can be used with any 3.5 mm earphone.

– The volume has 10 levels, from 0 to 9.

– The receiver has been pre-paired with the transmitter. Refer to the installation instructions to re-pair the devices if necessary.

– Display:

Top line: Signal strength, device status (locked or unlocked: only opens when the transmitter is paired), and battery level.
Bottom line: CH: Indicates the device’s channel. VOL: Indicates the current volume level. Press “VOL+” or “VOL-” to change it.

– In addition to the power button, the device has 2 keys (VOL+ and VOL-):

The power button is in the middle:
Turn on the transmitter: Press and hold the POWER button until the power LED and display appear.
Turn off the transmitter: Press and hold the POWER button until the power LED and display turn off.
Press the “VOL+” button to increase the volume and the “VOL-” button to decrease the volume.

– Unlock and change the receiver channel:

1. Turn off the receiver.
2. Press and hold the POWER and VOL+ buttons at the same time. The device will power on in unlocked mode (the lock icon will no longer be present).
3. Press VOL+ to increase the channel or VOL- to decrease the channel.
4. Wait 5 seconds, then the device will automatically lock again if nothing else is pressed (the lock icon returns to the screen).

– When the battery is depleted, you’ll need to recharge the receiver via the USB Type-C port or the charging case. The charging port is located on the bottom of the receiver.
– Turn off the receiver when not in use to conserve battery life. The receiver will automatically turn off 20 minutes after the last time it received a signal from the transmitter.

The use of receiver:

Connect the 3.5mm headset to the receiver and gently push the connector all the way in. Turn on the device and use it.

Common problems during use:

1. Turn on the power and the power LED does not light up.

Cause and solution: The transmitter has run out of battery and needs to be recharged.

2. The transmitter is working, but the receiver is not receiving signals (the signal column on the receiver’s display has NO bars).

Cause and solution: The transmitter may be in MUTE mode, or there is a mismatch between the transmitter and receiver channels. Deactivate MUTE mode or pair the two devices together.

3. The transmitter is working, but the receiver is not hearing any sound.

Cause and solution: The microphone may be mistakenly connected to the AUX port instead of the MIC port, or the headphones may not be fully connected or may be damaged. Try changing to a new pair of headphones.

4. The receiver has changed channels (different channel than the transmitter).

Cause and solution: The customer accidentally pressed the POWER and VOL+ buttons at the same time, causing the channel to change. Change to the transmitter channel using the instructions above or pair with the transmitter.

5. The screen is frozen, and the device cannot be turned on or off by pressing the button.

Cause and solution: The device has a software error. Connect a charger to the receiver (the receiver will turn off), then turn it back on and use it normally.
