7. Slowly pry the bottom of the chassis away from the front cover by pushing the chassis
opener tool down. Rotate 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 tabs.
8. Remove the chassis assembly by holding the chassis in one hand while slowly, with a
firm side-to-side motion, removing the chassis.
9. Lay the chassis down. Rotate the front cover backward and slightly away from the
chassis.
The chassis assembly has switches that can be damaged if the chassis
is removed too quickly. Be careful not to damage the switches at the
top of the board.
Figure 30. Chassis Separation
Flexible ribbon circuits (flexes) connecting the front cover assembly
and the chassis prevent you from completely separating the two units.
Display radios and radios with option boards have two flexes.
