Reassembly
To reassemble the radio:
1. Inspect the Main O-Ringon the Chassis (54) for any damage or foreign material.
2. Inspect the Battery Contact Seal (55) on the Main Board Assembly (45) for any damage.
3. Inspect the mating seal surfaces on the Chassis (54) for all of the above seals for damage or
foreign material that might prevent the seals from sealing properly.
Continue reassembling the radio according to
Tighten all hardware that was loosened or
removed.
8.7.7
Vacuum Test
The Vacuum Test uses a Vacuum Pump to create a negative pressure condition inside the radio. The
gauge measures this pressure and is used to Monitor any pressure changes in the radio. A properly
sealed, watertight radio should have minimal change in pressure during the test.
Before starting the vacuum test:
• Remove the battery and antenna.
• Remove the Vacuum Port Seal (56) and Ventilation Label (57) that cover the Vacuum port.
NOTE:
Refer to the exploded view diagrams and parts lists found in
8.7.7.1 Vacuum Tool Setup
1. Attach one end of the hose to the Vacuum Pump. Attach the other side of the hose to the
Vacuum Test Fixture (P/N: TL000059A01).
2. Tool Leak Test:
i.
Block the open end of the Vacuum Test Fixture.
ii.
Pull the knob on the Vacuum Pump to create vacuum.
iii.
Pump at least 15 in Hg.
iv.
Watch the gauge for a minute. If there is any loss of vacuum, repair or replace the tool.
3. Ensure that the seal is attached to the Vacuum Test Fixture.
NOTE:
The actual reading of the gauge at this point is not important; it is important that the gauge
pointer remained steady, indicating that there are no vacuum leaks in the pump.
Do not reassemble the radio without first performing the
following preliminary inspection procedure.
