3.6.1 Front Cover from Chassis Disassembly
1. Turn off the radio.
2. Pull down on the two battery-release buttons.
3. With the buttons pulled down, the top of the battery will fall from the radio.
4. Remove the battery completely from the radio.
5. Remove the antenna.
6. Using the chassis and knob opener tool, remove the volume and channel selector knobs off of
their shafts as shown in Figure 3-2.
NOTE Both knobs slide on and off. However, they are supposed to fit very tightly on their
shafts.
7. Separate the chassis from the internal electronics front cover assembly by inserting the chassis
and knob opener tool in between the thin retaining wall and the chassis at the bottom of the radio
as shown in Figure 3-3. Do not mar the housing O-ring sealing area.
8. Slowly pry the bottom of the chassis from the cover by pushing the chassis and knob opener tool
back while 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.
