4-12 Radio Reassembly — Detailed
7.4 Keypad Option Board, Microphone and Wire Reassembly
1. Replace the keypad/option board.
2. Insert the “top hooks” of the keypad retainer into the slots below the speaker in the front
cover. Snap all four of the retainer arm tabs in place in the front cover.
3. Re-insert the microphone and boot into the pocket in the front cover.
4. Lay the speaker-microphone wire on top of the keypad/option board retainer, align them onto
the catches and close the catches.
7.5 Chassis Assembly Reassembly
1. Replace the O-ring. The tabs on the O-ring should reach around the chassis and point down.
2. Stretch the O-ring to place it into the retaining pocket at the bottom end of the chassis.
3. Replace the battery contact seal (if necessary) surrounding the battery contact.
4. Place the main circuit board straight down on top of the chassis.
5. Use the T6 TORX screwdriver to fasten the screws holding the main board to the chassis.
NOTE
Pull the speaker-microphone wire out of harm’s way during reassembly.

NOTE
When properly assembled, the retainers on the O-ring should align with the slots on the
chassis. If this is not the case, remove and replace the O-ring until it is aligned with the
chassis and completely seated in place around the perimeter.
NOTE
Be sure the battery contact seal protrudes through the chassis and is not pinched under the
chassis.
