Question about Uniden GMR638-2CK (22 Channels) 2-Way Radio
The two handsets were working fine for over a year but for the last 2 days, when i press the buzzer or speak into either set, there is no sound / voice received in the other. this applies to both sets.
First of all check if the channel on both the radios are the same. If its a year, then also check the batteries on the sets and then the antenneas. If still no result, I suggest you get it done thru a service center.

To transmit to a radio that has QT noise filtering turned on:
1. Select the same channel and Interference Eliminator Code as the other radio.
2. Press 'musical note' button to send a call tone. This allows your voice to pass through the QT
noise filter on the receiving radio.
3. Press the PTT and speak normally.
Note: If you skip step 2, the beginning of your message may not be heard on
the receiving radio.
For a 30-second period, starting after the last transmission, all transmissions
received on the selected channel and code will pass through the QT noise filter.
Also, your QT filtering will NOT work if you are in scan mode.
