A. Disassembly
(Refer to the following diagrams and the exploded
view diagram located in the back of this manual.)
1. Turn off the radio by rotating the on/off/volume
control fully counterclockwise until you hear a
click. Remove the accessory connector cover or
any accessory connected to the radio before
beginning disassembly.
2. Remove the battery from the baseplate on the
bottom of the radio housing by pushing the spring-
loaded battery latch toward the top of the radio,
and sliding the battery away from the latch until it
clears the baseplate.
3. Loosen the two slotted-spanner nuts on the
bottom of the radio using the ROTO-TORQ
adjustable torque screwdriver with bit No.
66-80370B89. When loosened, the slotted-span-
ner nuts are captive and will spin freely without
separating from the baseplate.
4. Remove the chassis from the radio housing by
grasping the antenna at its base and pulling it
gently upward. Do not depress the PTT switch
during removal and do not push on the slotted-
spanner nuts to remove the chassis.
