5. Operating Instructions

5.1. Power On/Off

To power on the radio, rotate the power/volume knob clockwise until you hear a click and a tone. To power off, rotate the knob counter-clockwise until it clicks off.

5.2. Volume Adjustment

Rotate the power/volume knob to adjust the listening volume. Turn clockwise to increase volume and counter-clockwise to decrease.

5.3. Channel Selection

The RT22 radios have 16 pre-programmed channels. Use the channel selector knob (usually located near the antenna) to choose your desired channel. Ensure all radios in your group are on the same channel for communication.

5.4. Push-to-Talk (PTT)

To transmit, press and hold the large PTT button on the side of the radio. Speak clearly into the microphone. Release the PTT button to listen for a response.

5.5. VOX (Voice Operated Exchange)

The VOX function allows for hands-free transmission. When activated, the radio will automatically transmit when it detects your voice, without needing to press the PTT button. Refer to your specific user manual for instructions on how to activate and adjust VOX sensitivity.

5.6. Squelch Function

Squelch helps to suppress weak signals and background noise, providing clearer audio. The RT22 features an automatic squelch function. For optimal sound quality, ensure the volume is set appropriately.

5.7. Keypad Lock

To prevent accidental button presses, you can lock the keypad. Press and hold the "+" and "-" keys simultaneously. A "beep" sound will confirm the lock. Only the PTT key will remain functional. To unlock, press and hold the "+" and "-" keys again until two "beeps" are heard.

5.8. CTCSS/DCS (Sub-codes)

The RT22 radios support Preset CTCSS/DCS codes for more secure group communication. These sub-codes filter out unwanted conversations from other groups using the same main channel. Your radios are pre-programmed with these settings for enhanced privacy.

This image visually explains the Preset CTCSS/DCS feature, highlighting its role in enabling more secure and private group communications.

5.9. License-Free Operation

The Retevis RT22 radios operate on FRS (Family Radio Service) frequencies, which are license-free in the United States. This means they are ready to use out of the box without requiring any special permits or licenses.
