Frame
Assembly
The
tapped tabs
on the frame
can be stripped
if
excessive screw
tightening torques are used
(see
Torque
Specifications table). The
frame is not
repairable.
If
you must
lift
or remove the
PTT/controls flex
cir-
cuit for
any reason,
do not readhere
it
to the
frame;
the flex must be replaced.

Dual-Function Switch (S801) and
Actuator Assembly
Before removing the switch, remove the knob by
.
gently separating the
two arms of the switch
brack-
et (located between the switch and the main O-ring
seal)
and
pulling upward on the knob.
Before reinserting the knob, ensure that the slot
in
the switch is properly aligned with the blade on the
knob's shaft.
When the knob
is properly
inserted, the arms
of
the switch bracket
will
snap
into
position (approxi-
mately 0.2 inches apart), the knob
will not
be loose
in
the switch bracket, and the bracket
will hold
the
switch firmly against the inside
of
the top control
panel.
If
this is
not the
case,
replace the switch
bracket.

REASSEMBLY
Reassemble
the radio
in
the reverse order of
dis-
assembly, referring
to
"SERVICING MAJOR SUB-
ASSEMBLIES"
(Section 2) and making certain:
that the speaker/microphone connector and the
LCD
interconnect header are correctly aligned to
the main circuit board
so
that no twisting
or
pinch-
ing of the flexible circuit
occurs when
the
speaker
bracket is reattached
to
the frame assembly.
that all pads are correctly aligned.
that the two extended
tabs at the
top of the
speak-
er bracket are properly inserted into the
slots
between the frame and the control top panel.
to tighten all hardware
loosened
or
removed during
disassembly
per the torque specifications listed
in
the Torque Specifications table.
Use
recommended
torque driver (Motorola
RSX4043A
Rototorg Tool
or equivalent).
that there is no foreign material on the main O-ring
or stud
seals.
CAUTIONS
_
Inspect_the frame stud
seals
and the top
-
pane! O-ring and replace
if
any damage
exists
to properly orient the
completed frame assembly
