- CD Player Service Precautions

1.Before shipping out the repaired product, confirm the position of the DSP MODE switch; the switch should be set to the side that the customer previously selected.

If the switch is set to the STD side on the product where the NW side was selected, the speakers connected may be damaged.

2.For pickup unit(CXX1550) handling, please refer

to"Disassembly"(see page 62)

During replacement, handling precautions shall be

Dtaken to prevent an electrostatic discharge(protection by a jumper-solder).

3.During disassembly, be sure to turn the power off since an internal IC might be destroyed when a connector is plugged or unplugged.

4.Please checking the grating after changing the service pickup unit(see page 57).
