2. The charging indicator light will typically show red during charging and turn green when fully charged.
3. A full charge may take approximately 3-4 hours.

3.2. Attaching the Belt Clip

4. Operating Instructions

4.1. Power On/Off and Volume Adjustment

• Power On: Rotate the Power/Volume knob clockwise until you hear a click. The radio will emit a tone.
• Volume Adjustment: Continue rotating the Power/Volume knob clockwise to increase volume, or counter-clockwise to decrease volume.
• Power Off: Rotate the Power/Volume knob counter-clockwise until you hear a click.

4.2. Channel Selection

Use the Channel +/- buttons located on the top of the radio to select your desired communication channel. The RB617 supports 16 channels.

4.3. Transmitting and Receiving (PTT)

• To transmit, press and hold the PTT button on the side of the radio. Speak clearly into the microphone.
• To receive, release the PTT button.

4.4. VOX (Voice Operated Exchange)

The VOX function allows for hands-free operation. When activated, the radio will automatically transmit when it detects your voice, without needing to press the PTT button. Refer to the programming software for VOX sensitivity adjustment.

4.5. Emergency Alert

The RB617 includes an emergency alarm feature. When activated, the radio will emit a loud alarm tone to alert others to your situation. This feature can be configured via programming software for local or remote alarm types.

4.6. Squelch Function

Squelch automatically mutes the speaker when no signal is present, eliminating background noise. The squelch level can be adjusted via programming software to optimize reception in different noise environments.

4.7. Monitor Function

Press the Scan/Monitor button to temporarily disable the squelch and listen to all activity on the current channel, including weak signals that might otherwise be filtered out.

4.8. Busy Channel Lockout (BCL)

BCL prevents transmission on a channel that is already in use, avoiding interference with ongoing conversations. This feature is enabled by default.

4.9. CTCSS/DCS (Sub-tones)

CTCSS (Continuous Tone-Coded Squelch System) and DCS (Digitally Coded Squelch) sub-tones help filter out unwanted signals. When a CTCSS/DCS code is set, you will only hear communications from radios using the same code on the same channel. This enhances privacy and reduces interference from other users on the same frequency.
