7.6 Disassembly Procedures for SSE 5000 Radio
This section contains instructions for disassembling the radio.
NOTE: Numbers in parentheses ( ) refer to item numbers in Figure 7-1 on page 7-3 and Table 7-1 on
page 7-4 .
7.6.1 Separate the Chassis and Housing Assemblies
1. Turn the radio off by rotating the On/Off/Volume knob (33) fully counter-clockwise until you
hear a click.
2. Remove the battery, the universal connector dust cover or any accessory (other than the
antenna) connected to the radio.
NOTE: It is not necessary to remove the Volume knob (33) and insert (37) or Channel
Select knob (32) and insert (36) to service the chassis assembly (13). However, if
any top control is suspected, then the knobs and inserts should be removed prior to
removing the chassis assembly (13) from the housing assembly (1). See
Section
7.5.1.1: “Remove the Channel Select Knob” on page 7-11 and Section 7.5.2.1:
“Remove the Volume Knob” on page 7-11 .
3. Remove the two self-sealing bolts (59) on the bottom of the radio using a ROTO-TORQ
adjustable torque screwdriver with a T-10 TORX bit (see Table 7-2 on page 7-10 for part
numbers).
NOTE: Inspect the seals of the bolts after removal. If the seals are damaged, discard both
the seals and the bolts and replace with new self-sealing bolts.
4. Remove the chassis (13) from the radio housing (1) by grasping the antenna and gently
pulling upward to separate the assembly from the housing. Do not depress the PTT button
during removal.
NOTE: Inspect the universal connector insulator (10), located inside the housing on the
back face, for damage. If it is damaged, replace the insulator, taking care to ensure
that all contacts facing the inside of the radio are covered and keeping the insulator
away from the main o-ring (63) sealing area.
7.6.2 Disassemble the Chassis Assembly
NOTE: If the radio is equipped with hardware encryption, the encryption board (67) is attached to the
front side of the VOCON board (64) via a 40-pin connector.
