2.6 Radio Reassembly — Detailed
2.6.1 Chassis Assembly/Reassembly
1. Replace the battery contact seal (if necessary) surrounding the battery contact.
2. Remove the old Interface Pad from the chassis by scraping off the pad and adhesive with a
straight razor. Use rubbing alcohol and a cloth to completely remove the adhesive from the chas-
sis surface. With the chassis clean and dry, add a new Interface Pad to the chassis.
3. Place the main circuit board straight down on top of the chassis.
4. Use the T6 Torx screwdriver to fasten the screws holding the main board to the chassis. Tighten
to 3 in/lb.
5. Replacing the O-ring.
a. If you have the older chassis (2786389Z01) use the older O-ring (3286431Z02). Position
the O-ring in the top groove by the volume/frequency switches. Stretch the O-ring to
place it into the retaining groove at the bottom end of the chassis.
b. If you have the newer chassis (2786389Z02) use the newer O-ring (3286431Z05). Posi-
tion the O-ring with the plug on the right side (speaker connector side). Push the plug all
the way into the chassis slot until it is touching the chassis flange. Repeat for the left
side. Stretch the O-ring to place it into the retaining groove at the top and bottom end of
the chassis.
6. Replace the audio jack shroud.
7. Replace the microphone boot assembly.
2.6.2 PTT Reassembly
1. Place the PTT seal over the ridge around the top hole. Press down to seat the seal around the
ridge.
2. Place the bottom tab in the slot inside the front housing PTT opening. Slightly slide down the PTT
and bow it by placing one finger under the middle of the PTT, so that the top tab can be aligned
and inserted into the top slot (Figure 2-8a).
NOTE:
Be sure the battery contact seal protrudes through the chassis and is not pinched under the
chassis.
