4.6 DTMF Function and Privacy Protection
The TD-H3 supports DTMF functions, including a privacy protection feature:
- Kill Code: Set a 5-digit Kill Code via Odmaster. Any radio on the same frequency can dial this code to lock your H3. The radio will remain inactive until the same digits followed by "#" are sent. Example: 12345 to kill, 12345# to wake.
- Stun Code: Similar to the Kill Code, a Stun Code limits your H3 radio to receive signals only, preventing transmission.
4.7 Фенерче
The radio is equipped with a built-in flashlight for illumination in low-light conditions or emergencies.
5. Програмиране
The TD-H3 offers multiple programming methods for flexibility.
5.1 USB-C Programming
The radio features a built-in programming chip, allowing standard USB-C cables to be used for programming. Connect the radio to a computer using a USB-C cable and use compatible software (e.g., CHIRP, CPS) to configure channels and settings.
5.2 Wireless Programming (Phone App)
The TD-H3 supports wireless programming via a phone application (Odmaster App). This allows you to customize your radio settings from your smartphone anywhere, anytime.
5.3 CHIRP and CPS Programming
