Refitting
To refit the Processor module, proceed as follows:
(1) Place the module in position. Ensure no wires are trapped by the module. Ensure jumper J2 on
the module is set to ‘R/TR’ for transceiver (see Fig 1).

(2) Ensure the module’s interface connectors CN5 and CN6 are located correctly and are aligned
with the screw holes in the rear panel. Fit the four screwloc 8 mm-4-40 UNC screws and wavy
washers, previously removed, but leave them loose.
(3) Fit the seven M3 x 8 mm screws, previously removed, that secure the module to the transceiver’s
mainframe, but leave them loose.
(4) Using a nut spinner tool, tighten the four screwloc 8 mm-4-40 UNC screws and wavy washers
that secure the connectors; then tighten the seven M3 x 8 mm screws that secure the module to
the receiver’s mainframe.
(5) Refit the following connectors to the module:
‰
CN1 50-way connector (50-way ribbon cable from PA Control/Rx RF module)
‰
CN3 14-way connector (14-way ribbon cable from PSU Regulator module)
‰
CN4 34-way connector (34-way ribbon cable from Front Panel module).
‰
CN2 SMB connector (to PA Control/Rx RF module).
(6) Re-establish the ac and/or dc supplies.
(7) Switch power on at the radio using the rear mounted Power switch.
(8) Ensure the front panel Ready indicator is lit and the Alarm Indicator is unlit.
(9) If a new module has been fitted, connect the VFP PC to the radio using the PC to Radio
Interconnection Lead, Park Air part number 17E12600001 (if not already connected). Note that
any module sent from Park Air as a spare for a particular radio will be programmed with
compatible operating and Fill software. Park Air keeps records of module software in all radios
