5-38 Disassembly/Reassembly Procedures Ensuring Radio Immersibility
5.8.9.3 Battery Contact Seal
To replace the Battery Contact Seal:
1. Refer to Section 5.6 "Radio Disassembly – Detailed" on page 5-6 to remove the Battery
Contact Seal.
2. Remove the Battery Contact Seal from the Chassis.
3. Inspect the Battery Contact Seal, Chassis and surrounding areas for foreign material that
might prevent the Battery Contact Seal from sealing properly.
4. Install a new Battery Contact Seal; discard the old Seal.
5. Reassemble the chassis assembly followed by installing into front kit. (Refer to Section 5.7
"Radio Reassembly - Detailed" on page 5-20).
IMPORTANT: Both Ventilation Label (LB000256A01) and Ventilation Seal
(3286058L01) need to be replaced after vacuum test, pressure test or
water leakage troubleshooting.
5.8.9.4 Ventilation Seal and Ventilation Label
To replace the Ventilation Seal and Ventilation Label:
1. Remove the Ventilation Label that covers the Ventilation Seal from the chassis.
2. Remove the Ventilation Seal.
3. Ensure that the chassis’s surface (at the Ventilation Label & Ventilation Seal recessed) is
clean, no/minimum scratches and free from any adhesive or other foreign materials.
4. Install a new Ventilation Seal, covering the vent port hole, in the small recessed area in the
chassis. Ensure that no oily substance come in contact with the seal.
5. Install a new Ventilation Label over the Ventilation Seal in the larger recessed area in the
chassis. Press down evenly over the label’s surface to ensure good adhesion.
5.8.9.5 Battery Maintenance
1. As part of an Annual Battery Maintenece Program or as required (when the battery contacts
are dirty or show signs of wear) it is recommended that the Battery‘s Radio-side and Charger-
side contacts are cleaned with DeoxIT®GOLD cleaner/lubricant.
2. DeoxIT®GOLD (Supplier CAIG Labs, P/N G100P) cleaner/lubricant pen has been found to be
very effective at cleaning and extending the life of the battery‘s contacts. DeoxIT®GOLD
cleaner/lubricant is available at numerous electronics suppliers (Radio Shack, McMaster Carr,
Fry’s, etc.) and directly from manufacturer, CAIG Labs, at http://www.caig.com.
3. This pen based package is recommended as it provides better access to the recessed con-
tacts of the battery. The pen’s tip may need to be modified (trimmed on the sides) to improve
penetration into the battery contact slots. Per the manufacturer’s instructions, shake the pen
until the fluid begins to flow and wipe the battery's contact surface with the felt tip. After
cleaning, inspect the contact surfaces for signs of advanced wear.
4. Advanced contact wear is defined as wear through either the contact platings (gold and
nickel) to the base metal (copper). Copper exposure is characterized by a distinctive orange-
brown metal appearance surrounded by the silvery nickel underplate and gold top coat.
5. In some cases, a magnified (10x minimum) inspection may be required to verify wear through
to the base material. Polishing of the gold or nickel surface is common and is not considered
a need for replacement. In instances where advanced wear is evident, the battery should be
replaced.
