3.7.5 Chassis Assembly Reassembly
Before assembling the main RF board to the chassis, ensure that the following steps are done to the
chassis.
1. Slide on the ground contact (if it was removed) on the top corner boss of the chassis. Do not bend
the fingers that extend from this contact.
2. Replace the O-ring. The tabs on the O-ring should reach into the chassis and point down.
3. Stretch the O-ring to place it into the retaining pocket at the bottom end of the chassis.
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.
Before assembling the main RF board to the chassis, ensure that the following additional steps are
done to the chassis.
1. Ensure that the antenna nut insulator is correctly replaced by pushing it all the way to the top of
the antenna nut.
2. Replace the battery contact seal (if necessary) surrounding the battery contact.
3. Place the main circuit board straight down on top of the chassis.
NOTE Be sure the battery contact seal protrudes through the chassis and is not pinched
under the chassis.
4. Use the T6 TORX screwdriver to fasten the screws holding the main board to the chassis.
5. Do not over torque. Torque limit is 3 inch lbs.
3.7.6 Chassis and Front Cover Reassembly
1. Align the chassis assembly end-to-end with the front cover assembly.
2. Insert the tails of the flex circuits into their respective connectors at the bottom of the front cover.
3. Push down the latches on the connectors to hold the flex circuits to the main board.
4. Slide the volume potentiometer and frequency switch shafts into their respective holes in the front
cover.
5. Push the chassis assembly completely into the top of the front cover until it settles in place.
6. Be sure the O-ring is properly seated.
7. Snap the bottom of the chassis into the front cover.
8. Reassemble the knobs, dust cover, antenna, and battery.
