Caution

CAUTION

1:

Do not forcibly close the CD door when the power is off.

● Do not switch off the power when the CD ● To avoid damage, please don’t switch off the power until
door is open. “no disc” or “time code” is read on the display, always using

the open/close button to close the CD Door

2: To prevent destroying the anti-static protection for the mechanism, please kindly be noted of the following

important instruction for installing/disassembling the mechanism:

a. When disassembling the mechanism, please make sure to turn off power and short the Anti-static protection

welding point before removing the FFC cable.

b. When assembling the mechanism, please make sure to connect the FFC cable and PCB before removing the

Anti-static welding point, then, turn on the power.

FFC cord should be inserted in
PCB before pushing the static
solder protection aside. And
FFC cord won’t be took off till
shorten static protection when
taking Mecha apart.
