Chassis Assembly Reassembly

1. Slide on the ground contact (if necessary) on the top corner boss of the chassis.
2. Replace the O-ring. The tabs on the O-ring should reach around 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.
4. Ensure that the antenna nut insulator is correctly replaced by pushing it all the way to the top
of the antenna nut.
5. Replace the battery contact seal (if necessary) surrounding the battery contact.
6. 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.
7. Use the T6 TORX screwdriver to fasten the screws holding the main board to the chassis.
