Miscellaneous Operating Information
Microphone Hanger - The microphone hanger controls the monitor mode similar to the Monitor key (off-
hook = monitor). In addition, taking the microphone off-hook disables system and group scanning if it is enabled.
Telephone Calls - The phone mode can be selected by the P1 key and numbers can be sequentially recalled
from memory by pressing the P2 key. This can be done even if the transceiver is not equipped with the optional
telephone keypad. However, the optional keypad is required to enter numbers into the display or store numbers in
memory (a microphone keypad cannot be used). If the number is dialed using the microphone keypad, the phone
mode probably does not need to be selected.
Turning Power On and Off - Power to both the transceiver and control unit is controlled by the control unit
PWR switch. However, the vehicle’s ignition switch also normally controls power. Therefore, it must be in the On
or Accessory position for power to turn on. When the ignition switch is turned off and power has not been turned
off by the PWR switch, power remains on for the programmed delay period (see next description). The control unit
can also be installed so that the ignition switch does not control power. Power is then controlled only by the PWR
switch and a turn-off delay is not available.
Turn-Off Delay - When the ignition switch controls power as described in the preceding paragraph, there is a
turn-off delay that can be programmed by your system operator. This delay can be 0, 10, 20, or 30 minutes, 1, 2, or
4 hours, or an infinite time (no turn-off occurs). The delay period begins when the ignition switch is turned off
with the control unit power on. It can be canceled by turning power off using the PWR switch or turning the igni-
tion switch back on. This delay can be used to keep functions such as the Call indicator, horn alert, and battery
charger functional for a limited time after the vehicle is turned off. It can also be used to prevent accidental
discharge of the vehicle battery.
Horn Alert - The vehicle’s horn or some other type of alert can be used to signal an incoming call. It can be
programmed to activate when calls are received on specific groups or channels. When a call is received that acti-
vates the horn alert, the horn sounds once per second for 3 seconds and then deactivates. The horn alert is turned
on and off by the HORN button on the control unit. It is enabled when “HORN” is displayed. Other requirements
for the horn to sound are that the vehicle's ignition switch must be turned off and the control unit must be in the
delay period described in the preceding section.
Control Unit Display - The control unit displays the same unique 7-character system or 5-character group
identification as the transceiver display. Other information displayed in that area of the transceiver display is also
indicated by the control unit display. The control unit display and keys are continuously lighted (when power is
on) for use in low-light conditions
.
Sending Status Information
When the remote control unit is used, status information can be transmitted to your dispatcher when a Multi-Net
system is selected. If this feature has been programmed by your system operator, one of up to eight status conditions can
be selected using the STATUS key. The currently selected status condition is transmitted whenever the transmitter is
keyed. To momentarily display the currently selected status, press the STATUS key once. To change the status, press
this key again while this information is displayed. This cycles through the available choices. For example, status condi-
tions such as AT SITE, LVG SITE, or UNLOADING can be displayed. This information is not displayed by the trans-
ceiver display.
