Figure D-3: Removing the front panel from the chassis, using the battery as leverage

Removing the shield sub-assembly 
from the chassis

To remove the shield sub-assembly, place the 
radio’s internal assembly on a flat surface with 
the shield side facing up toward you. Press 
lightly down on the shield sub-assembly above 
the slot clip detail (shown in Figure D-4), 
which will slightly bow the shield away from 

the chassis.

Maintain pressure and insert a flat bladed 
screwdriver (approximately 4 mm) in the gap 
between the shield and the chassis. Twist the 
screwdriver and the shield should rise up over 
the clip.
