GENERAL FEATURES
22
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 24), two beeps sound instead of one to
indicate that an encrypted call is being placed, and speaking can begin as
soon as it sounds because it is delayed for the required time.
Home Channel Select
This feature is available if AUX1 or AUX2 is programmed for
Home Select. To quickly select the preprogrammed Home channel,
simply press the AUX switch programmed for that feature. The Home
channel is then displayed and it becomes the selected channel.
Horn Alert
If this feature has been installed by your dealer, it activates an
external alert such as the vehicle horn or lights when a call is received on
a channel programmed for horn alert. When the alert is enabled and the
proper call received, it turns on once per second for 3 seconds and then
goes back to the disabled state.
If the AUX1 or AUX2 switch is programmed to control horn alert as
described later, the decimal point indicator for that switch indicates when
the horn alert is enabled.
The horn alert is programmed to operate in one of the two modes
which are described below. Ignition switch control of power is described
in “Power Turn-Off Delay” on page 23. If the ignition switch does not
control transceiver power, only the front panel power switch affects oper-
ation of these modes.
Manual Off/On Mode
The current horn alert mode does not change when power is turned
on and off by either the ignition switch or power switch. Therefore, the
horn alert is entirely controlled by the AUX1/AUX2 switch if applicable.
