Operating Instructions
Basic Communication
- Power On: Rotate the power/volume knob clockwise until you hear a click and the radio announces the channel.
- Select Channel: Use the Channel + or Channel - buttons to select your desired channel. Ensure all radios you wish to communicate with are on the same channel.
- Transmit: Press and hold the Push-to-Talk (PTT) button on the side of the radio. Speak clearly into the microphone. Release the PTT button to listen.

Maintenance
IP67 Waterproofing
The Retevis RB47 radios are IP67 waterproof, protecting them from dust and water immersion up to 1 meter for 30 minutes. This makes them suitable for use in harsh weather conditions like rain and storms.
- Always ensure the waterproof cover of the earpiece jack is securely installed or fixed to prevent water damage.
- After exposure to water, wipe the radio dry with a clean cloth.
- Do not submerge the radio in water deeper than 1 meter or for longer than 30 minutes.
Battery Care
- Charge batteries fully before first use.
- Avoid overcharging or completely draining the battery.
- Store radios and batteries in a cool, dry place when not in use.
Troubleshooting
If you encounter issues with your Retevis RB47 radios, try the following common troubleshooting steps:
- No Power: Ensure the battery is fully charged and correctly installed. Check the power/volume knob is turned on.
- Cannot Transmit or Receive: Verify that all radios are on the same channel. Check that the PTT button is being pressed correctly. Ensure no obstacles are blocking the signal.
- Poor Audio Quality: Adjust the volume. Check for any obstructions around the microphone or speaker. Ensure radios are within range.
