With the TM8115, one function key can be programmed to toggle between
Clear and Secure mode. The Secure LED lights up when the radio is in
Secure mode. The radio has no facility to change the decryption/encryption
code via the user interface.
When the radio is set to Clear mode (unencrypted), the encryption module
does not affect the radio operation.
Unencrypted messages received while the radio is in Secure mode will be
received as normal, i.e. the radio does not apply any decryption.
To initiate a secure call:
1. Press the Clear/Secure function key (if not already in Secure mode).
The Secure LED lights up.
2. Press PTT to set up a call (assuming the other party has valid
decryption). You must wait at least 0.5s before speaking to allow the
receiving encryption module to synchronise.
3. Carry out the call in standard manner.
