To Remove A14 Signal Amplifier
Module
1 Ensure that the top cover and inner-RF (top) shield are removed.
2 Clip the wire tie that bundles the A19 input/output SMA connector
cable assemblies.
3 Clip the wire tie that bundles the A16 power/control/HV output
cables to the A19 ground strap(s).
4 Clip the wire tie that bundles the small-black CBT output coax, A19
power/control cable, and A16 power/control cable assemblies.
5 Disconnect the A19 A1P11 power/control cable assembly from A1J11.
6 Disconnect both input/output A19 SMA and SMB connectors from A19.
7 Remove the 2 round-head screws that mount the A19/A14 bracket
to the 5/16” thick vertical aluminum CBT bulkhead.
8 Carefully slide the A19/A14 bracket and units upward until the A14
connections are about even with the top of the CBT bulkhead.
9 While holding the A19/A14 units in this position, carefully
disconnect the A14 SMB CBT input cable connector and unplug
the 05071-60243 six-wire power and output connector from A14.
10 Place the A19/A14 modules/bracket on a clean-flat work surface.
11 Remove the three round-head screws that hold A19 to the three
rubber shock-absorbing grommets and mounting bracket.
12 Replace A19 with a new/functional module if replacement is
required at this time.
13 If A14 requires replacement, remove the 2 round-head screws that
hold it to the bottom of the A19/A14 mounting bracket.
14 Install a new/functional A14 module
15 Reverse the order of the appropriate steps to reinstall A19/A14.
NOTE
Be sure to tighten semi-rigid coax connector to 8.5 inch-pounds to
eliminate RF leakage.
