Radio Disassembly
and Reassembly
Disassembly 1. Turn off the radio by rotating the On/Off/Volume control fully
counterclockwise until you hear a click.
2. Remove the antenna, the battery, and the universal connector
cover or any accessory connected to the radio.
NOTE: It is not necessary to remove the volume knob (6)
and insert (7) or frequency knob (13) and insert (11)
to service the casting assembly. However, if any top
control is suspected, then the knobs and inserts
should be removed prior to removing the casting
assembly (51) from the housing assembly (2). Refer to
“Frequency Knob” on page 44 and “Volume Knob”
on page 47.
3. With the back of the radio facing
upward, insert the 6685833D01
special tool at the bottom of the
radio between the housing
assembly (2) and the two housing
tabs on the casting assembly (51)
until the special tool’s latch
engages the two battery tabs on
the casting assembly. With the
latch engaged, gently pull the
casting away to remove it from the
housing (do not use a prying motion). Making sure that the
antenna bushing has cleared the hole in the control top, carefully
lift the casting assembly clear of the housing assembly.
4. While holding the casting assembly (51) in one hand and the
housing assembly (2) in the other, unplug the 40-pin connector,
on the controls flex assembly (18), from the VOCON board (44).
NOTE: This can easily be done using the thumb of the
hand holding the housing assembly.
Put the housing assembly aside.
5. Remove the main seal (55) from around the casting assembly
(51).
6. If you are disassembling a model I radio, skip to step 9; if you are
disassembling a model II or III radio, continue this procedure.
With the front of the radio facing upward, unplug the 22-pin
connector for the LCD module (38) (located to the right and
above the LCD module). Lift the LCD module (38), with display
locator pad (39), up and off of the two locator posts on the
casting (51).
7. Remove the LCD module (38) and put it aside.
8. Unplug the 22-pin connector for the keypad flex (37) (located to
the left and above the LCD module area).
9. Pry upward on all four control locking clips (40) for the VOCON
6685833D01 Tool
