The one-key frequency match function allows for quick copying of frequencies from other transmitting radios:

3.5 Privacy Protection (DTMF Lock/Stun)

The TD-H3 offers privacy features using DTMF (Dual-Tone Multi-Frequency) codes:

• Kill Code: Set a Kill Code via Odmaster. Any radio with DTMF can send this code to remotely lock your H3 radio, preventing its use until unlocked.
• Stun Code: Set a Stun Code to limit your H3 radio to receive-only mode, preventing transmission.
• Codes should be at least 5 digits. To unlock, add '#' to the end of the code (e.g., 12345#).
