User Tips
- Frequency Programming is Key: For optimal performance and to utilize features like wireless copy and alarm, ensure your radio is properly programmed using the provided software. Pay close attention to the frequency range and specific function key assignments.
- Bluetooth Re-pairing: If you unpair your Bluetooth headset from the radio, remember to exit and re-enter the radio's pairing mode before attempting to re-pair. This ensures a fresh connection attempt.
- ການຄຸ້ມຄອງພະລັງງານ: While the RB689 boasts a high-capacity battery, managing power output can extend usage. Use the default 5W power for shorter distances to conserve battery life, and switch to 10W only when a wider range is necessary.
