Removal
Before attempting to remove the Processor module, and if possible, save the equipment settings. To
achieve this connect a PC, with the VFP software loaded, to the radio using the PC to Radio
Interconnection Lead (Park Air part number 17E12600001). With the VFP software active, upload the
radio settings to a specified file.
Ensure that the transceiver is isolated from the ac and dc input supplies. Then proceed as follows:
Dangerous voltages are present within the transceiver. Care must be taken by personnel to
avoid accidental contact with exposed circuitry when the top cover is removed and power is
applied to the radio.
(1) Remove the transceiver’s top cover as described on page 9.
(2) Locate the Processor module and disconnect the following connectors:
‰
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).
(3) Gain access to the rear of the transceiver. Using a 6BA nut spinner tool, remove the four
screwloc 8 mm-4-40 UNC screws that secure the Processor module interface connectors CN5
and CN6 to the rear panel.
(4) Remove the seven M3 x 8 mm screws that secure the module to the transceiver’s mainframe.
