LASERBEAMCAUTIONLABEL
PREPARATIONOFSERVICING
PickupHeadconsistsofalaserdiodethatisverysusceptibletoexternalstaticelectricity.
Althoughitoperatesproperlyafterthe replacement,ifitwassubjecttoelectrostaticdischargeduringreplacement,
thelifeof the product mightbeshortened.Whenreplacing,useaconductivemat,solderingironwithgroundwire,etc.
to keepthelaserdiode awayfromthe damagebystaticelectricity.
The above cautions are also applied to LSI and IC.

SAFTY NOTICE
Plug the AC line cord directly into 120V AC outlet (do
not use an isolation transformer for this check). Use an
AC voltmeter, having 5000 per volt or more sensitivity.
Connect 1500 10W resistor,paralleled by 0.15uF
150V AC capacitor between a known good earth ground
(water pipe, conduit, etc.) and all exposed metal parts of
cabinet (antennas, handle bracket, metal cabinet
screwheads, metal overlays, control shafts, etc.).
SAFTY PRECAUTIONS
LEAKAGE CURRENT CHECK
Measure the AC voltage across the 1500 resistor.
The test must be conducted with the AC switched on and
then repeated with the AC switched off. The AC voltage
indicated by the meter may not exceed 0.3.
Exceeding 0.3V indicates that a dangerous potential
exists, the fault must corrected.
Repeat the above test with aDVD VIDEO PLAYER
power plug reversed.
NEVER RETURN A DVD VIDEO PLAYER TO THE
CUSTOMER WITHOUT TAKING NECESSARY
CORRECTIVE ACTION.
READING SHOULD NOT EXCEED 0.3V

The lightning flash with arrowhead symbol, within an
equilateral triangle, 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
constitute a risk of electric shock to persons.
The exclamation point within an equilateral triangle is
intended to alert the user to the presence of important
operating and maintenance (servicing) instructions in the
literature accompanying the appliance.
