(7) Remove PCB screws (x8).
(8) Desolder the ANT Receptacle and Positive Terminal.

(9) Unlock the FPC connector and remove FPC cable from it,

then remove the PCB from Chassis.

(10) Untighten the screws of ANT Receptacle and circular nuts

of Variable Resistor (Volume) & Rotary Switch (Selector),
then remove ANT Receptacle, spring washers, Volume,
Selector from Chassis.

(11) Remove Rubber Seal & Holder Assy, Packing from

Chassis.

(12) Remove the Battery Release Lever from the front case.

• Press the upper part of the lever toward the inside of the

front case. One side of the shaft will be removed. <1>

• Lift and remove the battery release lever from the front

case. <2>

Note:

Scratch and widen the glue hole if there is difficulty in
removing the other end of the shaft.
No glue is required when you reassemble the battery
release lever.
