1 Safety Precaution
(This “Safety Precaution” is applied only in U.S.A.)
1.Before servicing, unplug the power cord to prevent an electric shock.
2.When replacing parts, use only manufacturer’s recommended components for safety.
3.Check the condition of the power cord. Replace if wear or damage is evident.
4.After servicing, be sure to restore the lead dress, insulation barriers, insulation papers, shields, etc.
5.Before returning the serviced equipment to the customer, be sure to make the following insulation resistance test to prevent the
customer from being exposed to a shock hazard.
■Insulation Resistance Test
1.Unplug the power cord and short the two prongs of the plug with a jumper wire.
2.Turn on the power switch.
3.Measure the resistance value with ohmmeter between the jumper AC plug and each exposed metal cabinet part, such as screw
heads, control shafts, handle brackets, etc. Equipment with antenna terminals should read between 3MΩand 5.2MΩto
allexposedparts. (Fig. A) Equipment without antenna terminals should read approximately infinity to all exposed parts. (Fig. B)
*Note: Some exposed partsmay beisolated from the chassis by design. These will read infinity.
(Fig. A)
(Fig. B)
4.If the measurement is outside the specified limits, there is a possibility of a shock hazard. The equipment should be repaired
and rechecked before it is returned to the customer.

2 Caution for AC Mains Lead
4
SL-DZ1200PP / SL-DZ1200EB / SL-DZ1200EG / SL-DZ1200EP / SL-DZ1200GN

The laser diode in the optical pick-up may break down due to
potential difference caused by static electricity of clothes or
human body.
So be careful of electrostatic breakdown during repair of the
optical pick-up.
3.1. Handling of traverse deck
optical pick-up
1.Do not subject the optical pick-up to static electricity as it is
extremely sensitive to electrical shock.
2.To protect the laser diode against electrostatic breakdown,
short the flexible board (FFC board) with a clip or similar
object. Refer to Fig. 2-1.
3.Take care not to apply excessive stress to the flexible board
(FFC board).
4.Do not turn the variable resistor (laser power adjustment). It
has already been adjusted. Refer to Fig. 2-1.
Fig. 2-1.
3.2. Grounding for electrostatic
breakdown prevention
3.2.1. Human body grounding
Use the anti-static wrist strap to discharge the static electricity
from your body. Refer to Fig. 2-2.
Fig. 2-2.
3.2.2. Work table grounding
Put a conductive material (sheet) or steel sheet on the area
where the optical pick-up is placed, and ground the sheet.
Refer to Fig. 2-3.
Fig. 2-3.
Caution:
The static electricity of your clothes will not be grounded
through the wrist strap.
So take care not to let your clothes touch the optical pick-
up.
