- To transmit, press and hold the PTT button on your radio. Speak clearly into the microphone.
- Release the PTT button to listen for a response.
Note on Compatibility: The channels are pre-set with CTCSS DCS to reduce unnecessary transmissions.

3. Emergency Alarm Function
The RT29 features an emergency alarm function designed to enhance safety in the workplace. This function can be assigned to one of the side keys (SK1 or SK2) via programming software.
- When activated, the radio will emit a loud alarm sound.
- If another RT29 radio is on the same channel, it will receive the alarm, and its indicator light will flash green, alerting team members to a potential emergency.
- The alarm will continue until the PTT button is pressed.

4. Voice Activated Transmit (VOX)
The RT29 supports 0-9 levels of voice activated transmit (VOX) function, allowing for hands-free operation. When VOX is enabled and a sufficient voice level is detected, the radio will automatically transmit. This feature can be configured via programming software.
Maintenance
1. Cleaning
Clean the radio's surface with a soft, damp cloth. Do not use harsh chemicals or abrasive cleaners. Ensure the charging contacts on the radio and charger are clean and free of debris.
2. Battery Care
- Avoid overcharging or completely draining the battery.
- 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. IP67 Waterproof and Dustproof
The RT29 is rated IP67, meaning it is completely dustproof and can withstand accidental immersion in water at a depth of 1 meter for 30 minutes. While rugged, proper care should still be taken:
- Ensure the battery pack is securely attached and all port covers are properly sealed before exposing the radio to water or dust.
- Do not intentionally submerge the radio for prolonged periods or beyond specified depths.
- If the radio gets wet, wipe it dry with a clean cloth before charging or opening any compartments.
