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.

ADVARSEL!

Lithiumbatteri Eksplosionsfare ved fejlagtig hndtering. Udskiftning m kun ske med batteri af samme fabrikat og type. Levr det brugte batteri tilbage til leverandren.
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 position is shown in the exploded views.
Denne advarsel or angivet p produktet eller i brugsvejledningen. Ved udskiftning af lithium batterierne flges nedenstende anveisning. Batterierne m kun udskiftes med batterier af samme type og mrke.
2. EXPLODED VIEWS AND PARTS LIST
NOTES : Parts marked by NSP are generally unavailable because they are not in our Master Spare Parts List. 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.

5. PCB PARTS LIST

NOTES : Parts marked by NSP are generally unavailable because they are not in our Master Spare Parts List. mark found on some component parts indicates the importance of the safety factor of the part. The 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 = 1 = 561... RD1/4PU 1 J 47k = 3 = 473.. RD1/4PU 3 J 0.5 = R50... RN2H K 1 = 1R0... RS1P K Ex. 2 When there are 3 effective digits (such as in high precision metal film resistors). 5.62k = 1 = 5621..

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 100C 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 position is shown in the exploded views.

ADVARSEL!

Lithiumbatteri Eksplosionsfare ved fejlagtig hndtering. Udskiftning m kun ske med batteri af samme fabrikat og type. Levr det brugte batteri tilbage til leverandren.
Denne advarsel or angivet p produktet eller i brugsvejledningen. Ved udskiftning af lithium batterierne flges nedenstende anveisning. Batterierne m kun udskiftes med batterier af samme type og mrke.

LABEL CHECK

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 TA2150FN (IC1101) on the RF AMP 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 34.
IMPORTANT THIS PIONEER APPARATUS CONTAINS LASER OF CLASS 1. SERVICING OPERATION OF THE APPARATUS SHOULD BE DONE BY A SPECIALLY INSTRUCTED PERSON.

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%). 561... RD1/4PU 1 J 560 473... RD1/4PU 3 J 47k 0.5 R50... RN2H R K 1 1R0... RS1P 1 R 0 K Ex.2 When there are 3 effective digits (such as in high precision metal film resistors). 5621.. RN1/4PC F 5.62k Description Part No. Mark No.

6. ADJUSTMENT

6.1 TEST MODE
Kind of test mode The following four modes exist. There is no information to be shown in this CD adjustment. 1-1. TEST mode. 1-2. Unit TEST mode. : For adjustment in main body distance of production line : For inspection by the function checker of production line
1-3. Service TEST mode. : For inspection by service It is not possible to operate at all by recognition because of there is no AC pulse if it is CD tuner alone and there is no part AMP as the power failure. Then, to be able to move the CD tuner, mode yet in the inconvenience without the part AMP. It is possible to operate only in the CD tuner even if the part AMP is not connected. An initial function becomes CD if the product starts in this mode, and CD becomes CD TEST mode different from a usual operation. Even if the function is returned to the CD function again, the product does not become CD TEST mode when the function is made functions other than CD once. The product becomes a usual CD operation. To put the product from the state in the CD TEST mode, the remote control code of A25F is received. 1-4. CD TEST mode. : For inspection by service When the remote control code of A25F is received at the CD function when it is on, power becomes CDTEST mode. The CD tuner is effective to this even the ordinary mode. However, the product becomes off this mode when the function is changed besides CD. The step in the part CD can operate.
