Mobile Installation
The SRPT-30/40A transmitter can be installed in the vehicle where the TRANSMIT/STANDBY function can be
operated directly, or the transmitter can be located elsewhere (in the trunk of a car or rear of a van) and controlled
remotely. The choice depends upon the type of vehicle and the type of operation anticipated. The antenna(s) are usually
mounted on top of the vehicle to provide maximum height.
Transmitter Mounting
1. Locate transmitter where vent holes on top and rear of unit are not obstructed. Leave enough space for the mic. Plug
on the front panel and the accessory plug on rear of unit.
2. Hook the four mounting fasteners (in retracted position in the four slots on the sides of the transmitter. See Fig. 1.
(Fasteners are in Mobile Mounting Kit, 700-251).
3. Mark the location of the two mounting holes in each fastener bracket. Drill 7/64” diameter holes into the mounting
surface at the marked places for #6 x 1/2” sheet metal screws.
4. Attach the mounting fasteners with the sheet metal screws provided. Secure the transmitter with the fasteners.
Receiver Mounting
For mobile repeat using the Marti AR-10 Mobile Repeat Receiver, mount the receiver near the transmitter using the
three fasteners supplied in Mobile Mounting Kit, 700-251.

Mobile Remote Control
Remote control of the SRPT-30/40A transmitter requires a switch to control primary 12-15 VDC power (or 15-30
VDC) and a second switch to control the transmit function. The primary 12-15 VDC (or 15-30 VDC) control
requirement can be met by tapping the ignition switch circuitry of the vehicle. The “transmit” function can be performed
by installing a switch on the vehicle.
