Retevis RT22 Two-Way Radio

Why can't my RT22 transmit?

First, confirm that the channel is not currently in use by another user. Second, check if the Time-Out Timer has been activated—if transmission exceeds 10 seconds, the radio will emit an alarm and stop transmitting automatically.

Do I need a license to use the Retevis RT22?

No, the RT22 operates on Family Radio Service (FRS) frequencies, which do not require a license in the U.S. This makes it suitable for personal and business use without licensing.

Can the RT22 communicate with other radios?

Yes, the RT22 can communicate with other FRS radios as long as they are set to the same channel and CTCSS (Continuous Tone-Coded Squelch System) code. The effective range is approximately 1-1.5 km in urban environments and up to 2-3 km in open areas.

Why does my RT22 have poor audio quality?

Verify that the antenna is securely attached to the radio. Also, adjust the volume to an appropriate level by rotating the power/volume knob. Poor antenna connection is the most common cause of audio quality issues.

How do I activate the VOX hands-free function on the RT22?

Press and hold the 'VOX' button to enable voice-activated transmission. You can adjust VOX sensitivity via the programming software if needed.

How do I lock the channel on the RT22?

In standby mode, press the 'Channel Up' and 'Channel Down' buttons simultaneously to lock the channel. Press both buttons again to unlock the channel and allow changes.
