1. SAFETY INFORMATION

LITHIUM BATTERY NOTICE

WARNING!

Lithium batteries. Danger of explo­sion. Replacement must be done by
qualified personnel and only by fol­lowing the instructions given in the
service manual.

This

warning is stated on the product or
in the operating instructions. When replac­ing the lithium batteries, follow the note
below.
Dispose

of

the used battery promptly.
Keep away from children. Do not disas­semble and do not dispose of in fire.
The battery used in this device may present
a fire or chemical hazard if mistreated. Do
not recharge,

disassemble, heat above

100°C or incinerate. Replace only with the
same Part Number. Use of another battery
may present a risk of fire or explosion.

Note: The lithium battery installation po-

sition is shown in the exploded views.

ADVARSEL!

Lithiumbatteri − Eksplosionsfare ved
fejlagtig håndtering. Udskiftning må kun
ske med batteri af samme fabrikat og
type. Levér det brugte batteri tilbage til
leverandøren.

Denne advarsel or angivet på produktet
eller i brugsvejledningen. Ved udskiftning

THIS PIONEER APPARATUS CONTAINS
LASER OF CLASS 1.
SERVICING OPERATION OF THE APPARATUS
SHOULD BE DONE BY A SPECIALLY
INSTRUTED PERSON.

IMPORTANT

LASER DIODE CHARACTERISTICS
MAXIMUM OUTPUT POWER: 5 mw
WAVELENGTH: 780 – 785 nm

NVXK type

Additional Laser Caution

1. Laser Interlock Mechanism
The loading position detect switch (in CD mechanism
assembly) is set to "CLMP ON(CD CLOSE)" (ON:low
level,OFF:high level) position, the system control
IC(IC5501) get the "CLMP" signal, and hand the laser
"LDON" signal to IC1101.
Then a laser diode can be lighted except when the level of
signal CLMP is low.

Printed on the Rear Panel

2

The interlock also does not function in the test mode∗.
Laser diode oscillation will continue, if pin 1 of CXA1821M
(IC1101) on the CDMAIN UNIT is connected to GND, or
pin 19 is connected to low level (ON), or else the terminals
of Q1101 are shorted to each other (fault condition).

2. When the cover is opened, close viewing of the objective
lens with the naked eye will cause exposure to a Class 1
laser beam.

∗ : Refer to page 41.
