GENERAL FEATURES
24
Call Indicator
The call indicator is “C” in the upper part of the display as shown in
the following illustration. The purpose of this indication is to show that a
call was received while you were away from the vehicle. Individual
groups can be programmed for this feature and it then turns on when a
call is received on one of those groups.
This indicator is turned off by pressing any button or turning trans-
ceiver power off and then on. If scanning and the “last received” configu-
ration is programmed (see “Transmitting In The Scan Mode” on
page 36), the system and group of the last call are displayed. Otherwise,
the currently selected system/group is displayed.
Emergency Switch
If the EMER option switch is programmed (see page 30), it is used
to set up a high priority call. When this switch is pressed,
“EMERGNCY” is displayed on the lower line (unless this message has
been disabled by programming) and a preprogrammed emergency
system/group is selected. However, no call is automatically placed. This
access mode minimizes, as much as possible, the chance that the system
will be busy when the call is placed by pressing the PTT switch. If you
have an EMER switch, consult your system operator for more informa-
tion on how to use it.
Encryption
Voice 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 similar encryption device.
