CAUTION: USE OF ANY CONTROLS, ADJUSTMENT, OR
PROCEDURES OTHER THAN THOSE SPECIFIED HEREIN
MAY RESULT IN HAZARDOUS RADIATION EXPOSURE.

Do not look directly at the laser beam
coming from the pickup or allow it to
strike against your skin.

This compact disc player uses a pickup that emits a laser beam.  The laser beam is emitted from the
location shown in the figure.  When checking the laser diode, be sure to keep your eyes at least 1 foot away
from the pickup lens when the diode is turned on.  Do not look directly at the laser beam.

CAUTION:

Using controls and adjustment, or doing procedures other than those specified herein, may result in
hazardous radiation exposure.

This symbol is intended to alert the user to
the presence of uninsulated "dangerous
voltage" within the product's enclosure that
may be of sufficient magnitude to consti-
tute a risk of electric shock to persons.

This symbol is intended to alert the user to
the presence of important operating and
maintenance (servicing) instructions in the
literature accompanying the appliance.

Caution:

To  prevent electric shock do not use this
(polarized) plug with an extension cord, recep-
tacle or other outlet unless the blades can be
fully inserted to prevent blade exposure.

Attention: Pour prevenir les chocs electriques ne pas

utiliser cetre fiche polarisee avec un
prolongateur, une prise de courant ou une au-
tre sortie de courant, sauf si les lames prevent
etre inserees a fond-sans en laisser aucune
partie a decouvert.

The laser diode in the optical system of this player can be damaged by electrostatic discharge from
your clothes or your body.  Proper electrostatic grounding for service personal is required during servicing.

Preparation
Human Body Grounding:
Many of the components used in this compact disc player, including the laser pickup, are sensitive to
electrostatic discharge.  Service personal should be grounded with an electrostatic armband (1 Mohm).

Caution:
Static charge on clothing does not escape through a body grounding wrist band.
Be careful not to contact the pickup or electrical components with your clothing.

Workbench and Tool Grounding:
A properly-grounded electroconductive plate (1Mohm) or metal sheet should be fitted to the workbench
surface.  Tools and instruments (such as soldering irons and scopes) should be grounded to prevent AC
leakage.

Note: Laser diodes are so susceptible to damage from static electricity that, even if a static discharge does
not ruin a diode, it can shorten its life or cause it to work improperly.

To prevent fire or shock hazard, do not
expose the unit to rain or moisture.
