ADJUSTMENT AND ALIGNMENT
There are no internal adjustments in the SRP9100. Re-programming and alignment is performed using
software tools. For testing, a special test jig is required so that the radio PCB can be powered and
input/output accessible. This test jig has a dummy battery and a connector that plugs into the top of the
radio so that the jig controls PTT and provides access to audio in and out.
As the radio has no internal adjustments, there is no need to have the radio PCBs powered while out of the
chassis. Field repair of the PCBs is not recommended as specialised equipment is required to fault find and
repair the boards.
