8.7.9

Troubleshooting Leak Areas

Before repairing any leak, first read all of the steps within the applicable section. This will help to 
eliminate unnecessary disassembly and reassembly of a radio with multiple leaks. 

NOTES:

All disassembly and reassembly methods can be found in 

Section 8.4.

 and 

Section 8.6.

8.7.9.1  Seal Interfaces 

• If leak occurs at one or more of the seal interfaces, disassemble the component(s) and inspect 

the interfaces to determine if there is any damage. If no damage is observed,
re-assemble the radio as directed.

• If damage has occurred, replacement parts will be needed.

8.7.9.2  Battery Contact Seal

• If leak occurs due to damage to the Battery Contact Seal (55), it will need to be replaced.

8.7.9.3  Front Housing

• If leak occurs through anywhere on the Front Housing, replace the Front Kit Assembly (A).

8.7.9.4  Keypad

• If leak occurs through the keypad (37), replace it.

8.7.9.5  Chassis 

• If leak occurs through the Main O-Ring (48), it will need to be replaced.
• If leak occurs elsewhere on the Chassis (54), it will need to be replaced.
