External Emergency Switch
When this function is programmed, an emergency condition can be triggered using an external
emergency switch such as a foot-operating type.
PA Broadcast
This function is used with the optional Transit Bus PA system to allow an external public address
select switch to be used instead of the normal front panel option switch.
2.6 REMOTE CONTROL UNIT INSTALLATION
NOTE: Refer to Section 2.10 for handheld control unit installation information.
2.6.1 GENERAL
The remote control configurations that may be used are as follows:
Single Remote - A remote control unit is connected to the remote mount radio (without operating
controls). This configuration is shown in Figure 2-2.
Single Remote, Dual Controls - A remote control unit is connected to the front mount radio.
This allows control from both the radio front panel and the remote control unit. This
configuration is a combination of Figures 2-1 and 2-2.
Dual Remotes - Two remote control units are connected to a remote mount radio. This allows
control from both remote control units. With this configuration, a second remote control unit
pigtail is used. One pigtail is connected to J6 on the logic board and the other to J1. This
configuration is similar to Figure 2-2.
Before installing the remote control units in the vehicle, check operation. If volume control is not
operating as desired, some DIP switches inside the control unit may need to be reconfigured.
Refer to the next section for more information.
NOTE: With dual control or remotes, for system power to turn off, the Power switches of both
control units must be off. Since the selected mode is not indicated by the push button switch, it is
recommended that only one control unit be used to switch power.
2.6.2 CONTROL UNIT BOARDS
Controller Board
The controller board uses only DIP switches for programming, as shown in Figure 2-7.
