DISASSEM BLY FOR REPAIR
Special care and attention required for assembly
1. Gluing to the key top (M IC element section)
You must also glue on the speaker storage area and heap
the glue up until w ealthy glued on the speaker storage area
and the key top for w aterproofing the M IC element side of
the key top. (Fig. 1)
Fig. 1
2. Bending the LCD hardware fixture (J21-8456-03) tabs
(1)Insert the tabs of the LCD hardw are fixture into four holes
in the LCD installing position of the TX-RX PCB (TX-RX unit
A/3). (Fig. 2)
Heap the glue up until w ealthy glued on the speaker
storage area and the key top (M IC element section).

(2)By pressing the LCD hardw are fixture from the component
side of the TX-RX PCB, you must bent all 4 tabs of the LCD
hardw are fixture being visible from the foil side until the
bases of each tabs are folded at least 45 degrees (Fig. 3). If
the bending angle of the tabs of the LCD hardw are fixture
is less than 45 degrees, a display error may occur.

3. PTT PCB (TX-RX unit C/ 3) installation procedure
Installing the PTT PCB on the TX-RX PCB and chassis are
as follow s:
(1)Insert the PTT PCB connector (CN7) into the TX-RX PCB
connector (CN6) lightly.
(2)Push three parts of the PTT PCB to contact tightly w ith the
chassis. There may be a small gap betw een the connectors.
(Fig. 4)
Note:
A double-side adhesive tape (J99-0376-04) is used
behind the PTT sw itch. When reassembling the PTT
PCB to the chassis, press the PTT PCB (under the PTT
sw itch) so that the tape hold the PCB and chassis
securely.
