<<Reassembly>>
For reassembly, reverse the disassembling procedure while paying attention to the following:
(1) When reassembling the Terminal Ass'y [65], be sure to mount the jack located internally on the left side
prior to the EB battery box. (The two parts cannot be assembled when mounted in reverse order.)
(2) Be careful not to mount the Jack [68] upside down. (It "can" be mounted upside down in the assembly
with the AA Battery Box [66] removed.)
(3) Be careful to prevent lead wires from being caught between other parts.
3. Disassembling and reassembling the front housing
Removing the function PCBA
<<Disassembly>>
(1) Remove three connectors, and then remove four Machine Screws (W/Flange) (M2.6 x 10) (Black) [19].
(2) Remove lead wires from the speakers by using a soldering iron.
(3) Move Function PCBA [21] aside a little, and then remove the Machine Screw (W/Flange) (M3 x 10)
(Black) [9] located near the end of the Rod Antenna [1]. Then you can remove the lead wire
connected to the Rod Antenna [1]. (Fig. 5)
(4) Remove Function PCBA [21].
<<Reassembly>>
For reassembly, reverse the disassembling procedure while paying attention to the following:
(1) When soldering lead wires on the speakers, carefully check the colors of lead wires for proper
connections.
Right speakers (found on the left in disassembled status): Lead wire colors are red (+) and blue (-).
Left speakers (found on the right in disassembled status): Lead wire colors are white (+) and blue (-).
(2) Do not forget to connect the lead wire to the Rod Antenna [1].
(3) When connecting each connector, be sure to fit it fully into the receptacle.
Removing the Control PCBA
<<Disassembly>>
(1) Remove the two Dials [6] from the front of the Front Housing Ass'y [8].
NOTE: Wrap a piece of thick cloth around each Dial [6], and then remove it with pliers or another
tool. Be careful not to damage the Dial [6].
(2) Remove five Machine Screws (W/Flange) (M2.6 x 10) (Black) [19]. Then you can remove Control PCBA
[17]. (Fig. 6)
Machine Screw (W/Flange) (M3 x 10)
(Black) [9] is located under Function
PCBA [21].
