5.4 DTMF Lock (Privacy Protection)

The DTMF Lock feature provides privacy protection by allowing you to remotely lock or stun a radio using DTMF codes.

• Kill Code: Setting a Kill Code on the Odmaster app allows another radio with DTMF functionality to send a code to lock your TD-H3, rendering it unusable until unlocked.
• Stun Code: Setting a Stun Code limits your TD-H3 radio to only receive signals.
• Codes should be at least 5 digits. For example, a Kill/Stun code could be 12345, and the unlock code would be 12345#.
