circuit board to the four housing ribs. Press the top right edge of the front circuit board to ensure
the microphone sealing rubber is fully seated in place.
5. Tighten the five screws holding the front circuit board with a Phillips screwdriver torque to
1.04 Ib-in – 1.30 Ib-in. (Refer Table 6-1 on page 6-14 for torque in other units).

1. Fit the Battery Contact Seal (24) onto the battery contact slot.
2. Fit the main O-ring (20) onto the chassis as follow:
a. Ensure that the main O-ring is not twisted. Untangle to original form if necessary.
b. Secure A into the bottom two notches on the chassis. (Refer Figure 6-16).
c. Fit the bottom section of the main O-ring around the bottom two grooves.
d. Insert B into the top two catches on the chassis.
e. Fit the top section of the main O-ring around the top two corners of the chassis.
f. Secure C into the remaining three notches on the chassis.
3. Place the main circuit board straight down on top of the chassis.
Note: Make sure the battery contact seal protrudes through the chassis and is not
squeezed under the chassis. Ensure the O-ring is also not squeezed under main
circuit board.
4. Tighten the six screws holding the main circuit board with a Phillips screwdriver torque to
