4. Remove the Volume Knob (4) from its shaft using the Chassis and Knob Opener.
(Refer Figure 7-3).
Chassis and Knob Opener
Note: The Volume Knob can be turned clockwise and counterclockwise. However, it is designed to
fit very tightly on the shaft.
5. Separate the Chassis (22) from the Front Housing Assembly (1):
a. Insert the Chassis and Knob Opener 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 housing by pushing the Chassis and Knob
Opener downwards, and prying the handle of the tool over and behind the base of the
radio. This forces the thin inner plastic wall toward the base of the radio thus releasing
the two chassis base tabs. (Refer Figure 7-4).
Marring the front cover O-ring sealing area will prevent the radio from sealing properly. If the
O-ring (19) is damaged, replace it with a new one.
