GENERAL FEATURES

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.

Call

Indicator

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.
