Disassembly/Reassembly
2.3.1
Receivers/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 the transmitter RF power module;
• 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.
Note:
All black finish Pozidriv screws used in the T889 are 4-40 UNC thread and
cannot be interchanged with M3 screws. Note that different lengths are
used in different applications.
