Encryption
Encryption is an optional feature that prevents conversations from
being monitored by casual eavesdropping and analog scanners. It does
this by encrypting your voice so that it can be understood only by
someone using a transceiver equipped with a similar encryption device.
Encryption is enabled and disabled by the ENCRYPT menu param-
eter (see page 36). If equipped with encryption and the menu parameter is
not available, encryption is always enabled. When encryption is enabled,
is indicated in the display as shown below.
To transmit an encrypted call, encryption must be enabled as just
described and the selected group must be programmed for encryption.
Encrypted calls are always received regardless of the currently selected
encryption mode and group programming (if the radio is equipped with
encryption). When transmitting an encrypted call, wait approximately
1 second before speaking. This gives the receiving transceiver time to
establish synchronization which ensures that all of the first word is
received. If the proceed tone is used and an encrypted call is transmitted,
two beeps instead of one sound and the tone is automatically delayed for
the required time.
Home System/Group Select
To select the preprogrammed Home system/group, simply press the
FCN HOME. The Home system/group programmed for the current bank
is then displayed and it becomes the selected system/group. If no home
system/group has been programmed, this function is not available.
