Note For Schematic Diagram; Warning And Laser Safety Instructions - Marantz ND8006 Service Manual

NOTE FOR SCHEMATIC DIAGRAM

WARNING:
Parts indicated by the z mark have critical characteristics. Use ONLY replacement parts recommended
by the manufacturer.
CAUTION:
Before returning the set to the customer, be sure to carry out either (1) a leakage current check or (2)
a line to chassis resistance check. If the leakage current exceeds 0.5 milliamps, or if the resistance from
chassis to either side of the power cord is less than 460 kohms, the set is defective.
WARNING:
DO NOT return the set to the customer unless the problem is identified and remedied.
NOTICE:
(1) ALL RESISTANCE VALUES IN OHM. k=1,000 OHM / M=1,000,000 OHM
(2) ALL CAPACITANCE VALUES ARE EXPRESSED IN MICRO FARAD, UNLESS OTHERWISE INDICATED. P
INDICATES MICRO-MICRO FARAD. N INDICATES NANO FARAD.
(3) EACH VOLTAGE AND CURRENT ARE MEASURED AT NO SIGNAL INPUT CONDITION.
(4) CIRCUIT AND PARTS ARE SUBJECT TO CHANGE WITHOUT PRIOR NOTICE.
HANDLING THE SEMICONDUCTOR AND OPTICS
Electrostatic breakdown of the semi-conductors or optical pickup may occur due to a potential differ-
ence caused by electrostatic charge during unpacking or repair work.
1. Ground for Human Body
Be sure to wear a grounding band (1 M ohm) that is properly grounded to remove any static electricity
that may be charged on the body.
2. Ground for Workbench
Be sure to place a conductive sheet or copper plate with proper grounding (1 M ohm) on the workbench
or other surface, where the semi-conductors are to be placed. Because the static electricity charge
on clothing will not escape through the body grounding band, be careful to avoid contacting semi-
conductors with your clothing

WARNING AND LASER SAFETY INSTRUCTIONS

GB WARNING
All ICs and many other semi-conductors are
susceptible to electrostatic discharges (ESD).
Careless handling during repair can reduce life
drastically.
When repairing, make sure that you are connected
with the same potential as the mass of the set via a
wrist wrap with resistance.
Keep components and tools also at this potential.

LASER SAFETY
This unit employs a laser. Only a qualified service person should
remove the cover or attempt to service this device, due to
possible eye injury.
USE OF CONTROLS OR ADJUSTMENTS OR PERFORMANCE
OF PROCEDURE OTHER THAN THOSE SPECIFIED HEREIN
MAY RESULT IN HAZARDOUS RADIATION EXPOSURE.
AVOID DIRECT EXPOSURE TO BEAM

NL WAARSCHUWING
Alle IC's en vele andere halfgeleiders zijn gevoelig
voor elektrostatische ontladingen (ESD).
Onzorgvuldig behandelen tijdens reparatie kan de
levensduur drastisch doen verminderen.
Zorg ervoor dat u tijdens reparatie via een polsband
met weerstand verbonden bent met apparaat.
Houd componenten en hulpmiddelen ook op
ditzelfde potentiaal.
WARNUNG I AVVERTIMENTO
Tutti IC e parecchi semi-conduttori sono sensibili
alle scariche statiche (ESD).
La loro longevita potrebbe essere fortemente ridatta
in caso di non osservazione della piu grande
cauzione alla loro manipolazione.
Durante le riparazioni occorre quindi essere
collegato allo stesso potenziale che quello della
massa dell'apparecchio tramite un braccialetto a
resistenza.
Assicurarsi che i componenti e anche gli utensili
con quali si lavora siano anche a questo potenziale.
D
Bei jeder Reparatur sind die geltenden Sicherheitsvorschriften zu beachten.
Der Originalzustand des Gerats darf nicht verandert werden.
Fur Reparaturen sind Original-Ersatzteile zu verwenden.
I
Le norme di sicurezza esigono che l'apparecchio venga rimesso nelle
condizioni originali e che siano utilizzati pezzi di ricambiago idetici a quelli
specificati.
