Setup Guide
1. Battery Installation
- Align the battery pack with the grooves on the back of the radio.
- Slide the battery pack upwards until it clicks into place.
- To remove, press the battery release latch and slide the battery downwards.
2. Antenna Attachment
- Screw the antenna clockwise into the connector on the top of the radio until it is finger-tight. Do not overtighten.
3. Charging the Battery
- Insert the power adapter into an electrical outlet.
- Connect the adapter cable to the charging base.
- Place the radio (with battery installed) into the charging base. The charging indicator light will illuminate.
- A full charge typically takes 4-5 hours. The indicator light will change color or turn off when charging is complete.
4. Earpiece Connection
- Open the rubber cover on the side of the radio.
- Insert the earpiece plug firmly into the audio jack.
Operating Instructions
1. Power On/Off and Volume Adjustment
- To power on, rotate the volume knob (top-left) clockwise. You will hear a click and a tone.
- Continue rotating the knob clockwise to increase volume, and counter-clockwise to decrease.
- To power off, rotate the volume knob counter-clockwise until you hear a click.
2. Channel Selection
- Use the UP/DOWN arrow keys on the keypad to navigate through available channels.
- Alternatively, enter the channel number directly using the numeric keypad.
- Press the MENU button to access the menu for advanced settings, including frequency input.
3. Transmitting and Receiving
- To transmit, press and hold the PTT (Push-To-Talk) button on the left side of the radio. Speak clearly into the microphone.
- Release the PTT button to receive.
- Ensure the antenna is properly attached for optimal performance.
4. VOX Function (Hands-Free Operation)
- The VOX function allows transmission without pressing the PTT button.
- To activate/deactivate and adjust VOX sensitivity (levels 0-9), navigate through the radio's menu settings. Refer to the on-screen menu for specific steps.
5. Squelch Adjustment
- Squelch filters out weak signals and background noise.
- Adjust squelch levels (1-9) via the radio's menu. Higher levels require stronger signals to open the receiver.
6. Keyboard Lock
- To prevent accidental key presses, activate the keyboard lock function.
- Typically, this is done by pressing and holding the '#' key or through the menu.
7. Emergency Alarm and Flashlight
- The emergency alarm can be activated via a dedicated button (often labeled CALL or FM) or through the menu.
- The built-in flashlight is usually activated by a short press of the FM button or a dedicated side button.
8. CHIRP Programming
- For advanced programming of frequencies, tones, and other settings, the RT-5R supports CHIRP software.
- A programming cable (sold separately) and a computer are required.
- Download the latest CHIRP software and drivers from the official Retevis website or CHIRP project website.
Maintenance
1. Cleaning

- Ensure the charging contacts on both the radio and the base are clean and free of debris.
2. Battery Care
- Avoid fully discharging the battery frequently to prolong its lifespan.
- Store batteries in a cool, dry place when not in use.
- If the radio will not be used for an extended period, remove the battery.
3. Storage
- Store the radio in a dry, dust-free environment away from direct sunlight and extreme temperatures.
- Keep the radio away from strong magnetic fields.
