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.

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.

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.

How do I charge the Retevis RT22 battery?

Connect the USB charging cable to the radio's charging port and plug the other end into a USB power source. Allow the battery to charge fully before first use. The RT22 uses a built-in rechargeable lithium-ion battery.

How do I turn on and off the Retevis RT22?

Rotate the power/volume knob clockwise to turn on the radio. Rotate the knob counterclockwise to turn off. The same knob is used for both power control and volume adjustment.
