GENERAL FEATURES
25
Each group can be programmed so that when it is selected, encryp-
tion is automatically enabled. When encryption is enabled, is indi-
cated in the display as shown below.
If you have the ENCRYPT menu parameter or ENCPT option
switch, the encryption group programming can be temporarily over-
ridden. Selecting another system or group causes encryption to revert to
the status programmed for that group.
Encrypted calls are received even if encryption is not enabled.
However, encryption must be enabled to transmit an encrypted call.
When transmitting an encrypted call, wait approximately 1 second before
speaking. This gives the receiving encryption device time to establish
synchronization which ensures that all of the first word is received. If the
proceed tone is used (see page 28), speaking can begin as soon as it
sounds because it is delayed for the required time.
Function (FCN) Switch
If an option switch is programmed for FCN (function), it performs
the following functions. If this switch is not programmed, these functions
are not available. When the function select mode is active, “FCN” is
displayed on the lower line of the display. The function mode is automati-
cally exited after 8 seconds of no activity.
