[ Important symbols for good services ]
In this manual, the symbols shown-below indicate that adjustments, settings or cleaning should be made securely.
When you find the procedures bearing any of the symbols, be sure to fulfill them:
1. Product safety
You should conform to the regulations governing the product (safety, radio and noise, and other regulations), and
should keep the safety during servicing by following the safety instructions described in this manual.
2. Adjustments
To keep the original performances of the product, optimum adjustments or specification confirmation is indispensable.
In accordance with the procedures or instructions described in this manual, adjustments should be performed.
3. Cleaning
For optical pickups, tape-deck heads, lenses and mirrors used in projection monitors, and other parts requiring cleaning,
proper cleaning should be performed to restore their performances.
4. Shipping mode and shipping screws
To protect the product from damages or failures that may be caused during transit, the shipping mode should be set or
the shipping screws should be installed before shipping out in accordance with this manual, if necessary.
5. Lubricants, glues, and replacement parts
Appropriately applying grease or glue can maintain the product performances. But improper lubrication or applying
glue may lead to failures or troubles in the product. By following the instructions in this manual, be sure to apply the
prescribed grease or glue to proper portions by the appropriate amount.For replacement parts or tools, the prescribed
ones should be used.
Before shipping out the repaired product, confirm the
1.
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
D
taken to prevent an electrostatic discharge(protection
by a jumper-solder).
