Emergency Switch
If the EMER option switch is programmed (see page 35), it is used
to quickly select the emergency system/group that has been programmed
in the current bank. The emergency call must then be manually trans-
mitted by pressing the PTT switch (automatic transmissions do not
occur). Scanning continues if it is enabled, and calls are received
normally on other systems and groups if applicable.
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 or Encryption option switch (see page 35). If equipped with encryp-
tion and neither the menu parameter nor the option switch is available,
encryption is always enabled. When encryption is enabled, is indi-
cated 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.
