3. How to Assemble the Antenna Connec-
tor and its Terminal
The antenna connector and its terminal are supplied as
separate parts.
When replacing the antenna connector and/ or terminal,
assemble the parts prior to the replacement.
1) Mount the antenna connector onto the chassis ( q ).
Double-sided tape is attached to the terminal; peel off the
tape cover ( w ).
Attach the terminal to the antenna connector as shown
below.
Slide the antenna terminal along the adhesive cushion on
the chassis so that the adhesive part on the terminal is
firmly attached to the antenna connector ( e ).
2) Remove the antenna connector from the chassis with its
terminal attached, then solder the center part of antenna
connector to its terminal ( r ).
Do not use excessive solder on terminal.
DISASSEMBLY FOR REPAIR
1. Removing the FPC
1) Remove the solder from the TX-RX unit using a solder iron
( q ).
2) Peel the double-sided tape ( w ).
3) Remove the solder from the battery terminal block using
the solder iron ( e ).
Note : You must replace the FPC and the double-sided tape
(4 x 7 mm) when replacing the volume or the selector.
2. Separating the Speaker Holder from
the Control Unit
1) As in shown in the figure below, the speaker holder is at-
tached to the LCD cover with tab ( q ).
Use a pair of tweezers or similar instrument to lift the
speaker holder away from the control unit ( w ).
