(No.MA377)1-15 3.2.2 Removing the push switch
(See Figs.3)
(1) From the bottom side of the CD mechanism assembly, remove
the screw B attaching the push switch.
(2) Take out the push switch from the CD mechanism assembly.
Reference:
Remove the wires from soldered sections b of the push switch
as required.
3.2.3 Removing the base board
(See Figs.3 and 4)
Caution:
Solder the short land c before the flexible wire is disconnected from
the connector on the pickup. If the flexible wire is disconnected
without applying solder, the pickup may be destroyed by static
electricity. (See Fig.3.)
(1) From the bottom side of the CD mechanism assembly, remove
the screw C attaching the base board. (See Figs.3 and 4.)
(2) Solder the short land c on the pickup. (See Fig.3.)
(3) Disconnect the flexible wire from the connector on the pickup.
(See Fig.3.)
(4) Remove the base board from the joints d of the frame in the
direction of the arrow. (See Figs.3 and 4.)
Reference:
Remove the wires from the soldered sections e on the base
board as required. (See Fig.3.)
Caution:
When reattaching the base board, be sure to remove solder
from the short land c after connecting the flexible wire. (See
Fig.3.)Fig.3
