Replace Damaged
or Missing Seals
and Bungs
Remove any damaged seal or bung. Obtain a replacement seal for the
RF connector or a replacement bung from Spares kit 2. The contents of
the kit are listed in Table 6.2 of Section 6 (on page 125). Order a
replacement cover seal (and screws) from TEL; the IPNs of the parts are
listed in Table 2.2. 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 the tasks given in
Subsection 5.2 (on page 109) — 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 Subsection 5.3 (on page 121).
Replace Damaged
Cover Assembly
Remove a damaged cover assembly as described in Subsection 6.3
(on page 137). Obtain a replacement assembly from Spares kit 2. The
cover assembly comprises a cover and a label, as shown in Figure 2.8; the
label is permanently fixed to the cover. The IPNs of both items are given
in Table 6.2. If a spares kit is not available, order both items from TEL.
Fit the replacement cover assembly to the radio body.
Repair Damaged
Control Head
If the control head is damaged, detach it from the radio body as described
in Subsection 6.1 (on page 127). 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 Subsection 6.2
(on page 131). Obtain replacement parts from Spares kit 1 (two-digit-
display control head) or Spares kit 10 (one-digit-display control head).
Then re-assemble the control head and re-attach it to the radio body as
described in Subsection 6.5 (on page 148).
