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.

LABEL CHECK

MYXK type

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
af lithium batterierne følges nedenstående
anveisning.
Batterierne må kun udskiftes med batteri­er af samme type og mærke.

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.
The interlock also does not function in the test mode∗.
Laser diode oscillation will continue, if pin 1 of CXA1821M
(IC1101) on the RF 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 42.

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

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

NOTES:•The mark found on some component parts indicates the importance of the safety factor of the part.

Therefore, when replacing, be sure to use parts of identical designation.
When ordering resistors, first convert resistance values into code form as shown in the following examples.

•

Ex.1 When there are 2 effective digits (any digit apart from 0), such as 560 ohm and 47k ohm (tolerance is shown by J=5%,
and K=10%).

560 Ω→56 × 10
47k Ω→47 × 10

0.5 Ω→R50 ..................................................................................... RN2H

→ 561 ........................................................ RD1/4PU 5 6 1 J

3

→ 473 ........................................................ RD1/4PU 4 7 3 J

R 5 0

K

1 Ω→1R0 ..................................................................................... RS1P 1 R 0 K

Ex.2 When there are 3 effective digits (such as in high precision metal film resistors).

5.62k Ω→ 562 × 10
