2.3 Disassembly/Reassembly
2.3.1 Receivers/Exciters/Transmitters
To carry out alignment or change option links, you need to remove only the top cover,
i.e. the one adjacent to the front panel handle and on the opposite side to the main
D-range connector (D-range 1/PL100).
You need to remove the bottom cover to:
• access transmitter RF power transistors and many SMD components
• change solder blob links
• fit test leads to circuit block access points.
2.3.2 Power Amplifiers
You should carry out the tuning and power output level setting procedures with the
cover on.
