ENCRYPTION
Encryption means encrypt the voice or data of the
end-to-end, which provides reliable security for voice or
data, and can effectively prevent eavesdropping or stolen.

1.Basic Encryption

Radio only can allocate one of the above encryption types.
To decrypt the encrypted call or transmission data, the pre
programmed radio must have the same "encrypted key"
with transmitted radio (suitable for basic encryption).
If your radio receives an encrypted call from a different
encryption key or a different key value and a key ID, you will
hear the sound of a messy transmission (basic type
encryption).
Press preset [Encryption] key to turn on or off the encryp-
tion function..
Note: In conventional mode, open encryption is the
encryption of the current channel. When the channel is
switched, the terminal will automatically turn on encryption.
