The bung for aperture for external options connector should be replaced by
a cover seal if an external options connector is present. All the parts are
illustrated in

grommet, if any of these parts is missing or damaged, replace it as described
below. In the case of the microphone grommet, refer to the accessories
section for the repair procedure.
Replace Damaged
or Missing Knob
Remove the volume-control knob if it is damaged. Push the replacement
knob onto the shaft of the volume-control potentiometer. Ensure that the
knob turns freely.

Remove any damaged seal or bung. Obtain a replacement seal for the
RF connector or a replacement bung from Spares kit 2. Order a
replacement cover seal (and screws) from TEL; the IPNs of the parts are
listed in
“Spare Parts” on page 455 . In fitting a replacement bung, ensure
that it is not upside down and that it is properly seated. To fit the seal for the
RF connector, first fit the upper part of the seal and then press down around
the sides of the seal to the bottom. Ensure that the seal is properly seated
around its entire periphery.
Check for
Additional Damage
Also check for damage to exterior parts that can be replaced only by partly
disassembling the radio. These parts are:
■
cover assembly for radio body
■
keys, lens and LCD of control head
■
front panel of control head.
In the case of the front panel, inspect particularly the light pipes for the
STATUS
LEDs and the membrane behind the speaker grille. If the radio is
reported to have a functional fault, continue with Task 3 . Any additional
mechanical damage will be repaired during the course of rectifying the
functional fault. If the radio has no functional fault, repair any additional
damage as described below; conclude with the tasks of
“Final Tasks” on
page 163 .
Repair Damaged
Control Head
If the control head is damaged, detach it from the radio body as described
in
“Removing and Mounting the Control Head” on page 136 .
The procedure includes inspecting the interior of the control head for
evidence of other damage. Disassemble the control head and repair all
damage as described in
“Disassembling and Reassembling the Control
Head” on page 147 . Then re-assemble the control head and re-attach it to
the radio body.
