Radio Disassembly — Detailed
4.
Pull the volume and channel selector knobs off of their shafts.
NOTE
Both knobs slide on and off. However, they are supposed to fit very tightly on their shafts.
5.
Separate the chassis from the internal electronics front cover assembly as follows:
a.
Insert a small, flat-blade screwdriver, or similar instrument, in between the thin retaining
wall and the chassis at the bottom of the radio. Do not mar the O-ring sealing area on the
housing.
b.
Slowly pry the bottom of the chassis from the cover by pushing the small flat-blade
screwdriver down, and rotating the handle of the tool over and behind the base of the
radio. This prying action forces the thin inner plastic wall toward the base of the radio,
releasing the two chassis base tabs.
CAUTION: Marring the front cover O-ring sealing area will prevent the radio from sealing properly.
!
NOTE
Flexible ribbon circuits (flexes) connecting the front cover assembly and the chassis pre-
vent you from completely separating the two units. Display radios and radios with option
boards have two flexes.
