GENERAL FEATURES

Automatic Operation - The transmitter automatically transmits an emer- gency message on the emergency system/group. The message is trans- mitted without pressing the PTT switch and at the highest priority. Emergency transmissions continue until an acknowledgment is received from the dispatcher.

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.

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.

Encryption

Indicator

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 30), speaking can begin as soon as it sounds because it is delayed for the required time.
