Standby mode
CES-128 voice encryption provides a standby mode in which the transceiver receives
signals in clear, and automatically switches to secure mode if it detects a secure
transmission. When the encryptor is in standby mode, any transmissions that you
make will be in secure mode, by default. If you want transmissions to be in clear mode
while the encryptor is in standby mode, you can set this in Settings > Security >
CES Options.
A brief standby period may be set following a call made in an HF network using a
Selcall call system. This period enables you to hear the revertives that are sent from
the called station. The encryptor goes to secure mode after the standby period. The
standby period is set in Settings > Security > Standby After Selcall.
The encryptor allows secure operation to remain on during scanning. Secure standby
mode is permitted and remains on until * is pressed again.
