GB

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.

WARNING

GB

Safety regulations require that the set be restored to its original condition and that parts which are identical with those specified, be used

For sets which are compatible with CD-RW discs

use CD-RW Printed Audio Disc....................7104 099 96611

TR 3 (Fingerprint) TR 8 (600µ Black dot) maximum at 01:00

• playback of these two tracks without audible disturbance playing time for: Fingerprint

• jump forward/backward (search) within a reasonable time

For all other sets

use CD-DA SBC 444A..................................4822 397 30245

TR 14 (600µ Black dot) maximum at 01:15 TR 19 (Fingerprint) TR 10 (1000µ wedge)

LIQUID LENS CLEANING

Before touching the lens it is advised to clean the surface of the lens by blowing clean air over it. This to avoid that little particles make scratches on the lens.

Because the material of the lens is synthetic and coated with a special anti-reflectivity layer, cleaning must be done with a non-aggressive cleaning fluid. It is advised to use “Cleaning Solvent

The actuator is a very precise mechanical component and may not be damaged in order to guarantee its full function. Clean the lens gently (don’t press too hard) with a soft and clean cotton bud moistened with the special lens cleaner.

The direction of cleaning must be in the way as indicated in the picture below.

CUSTOMER INFORMATION

It is proposed to add an addendum sheet to the set which informs the customer that the set has been checked carefully - but no fault was found. The problem was obviously caused by a scratched, dirty or copy-protected CD. In case problems remain, the customer is requested to contact the workshop directly. The lens cleaning (method 3) should be mentioned in the addendum sheet.

The final wording in national language as well as the printing is under responsibility of the Regional Service Organizations.

LV47002P Development Specification Proposal

(BTL 4 channel Car Audio Power Amplifier)

The LV47002P is the IC for 4-channel BTL power amplifier that is developed for car audio system. Pch DMOS in the upper side of the output stage and Nch DMOS in the lower side of the output stage are complimentary. High power and high quality sound are realized by that. This IC incorporate various functions (standby switch, muting function, and various protection circuit) necessary for car audio system. Also, it has a self-diagnosis function.

1. Application : 4-channel BTL power amplifier for car audio system

2. Package type : HZIP25

3. Functions and Features :

- High power : - Pomax=48W (typical) (Vcc=15.2V, f=1kHz , JEITAmax , RL=4Ω)

- Po = 28W (typical) (Vcc=14.4V, f=1kHz , THD=10% , RL=4Ω)

- Po = 21W (typical) (Vcc=14.4V, f=1kHz , THD=1% , RL=4Ω)

- Built-in muting function (pin 22)

- Built-in Standby switch function (pin 4)

- Built-in Self-diagnosis function (pin 25) : Signal output in case of output offset detection, shorting to VCC,

shorting to ground , and load shorting.

- Electric mirror noise decrease

- Built-in various protection circuit (shorting to ground, shorting to VCC, load shorting, over voltage and

thermal shut down )

- No external anti-oscillation part necessary.

Note1 : Please do not mistake connection. A wrong connection may produce destruction, deterioration and damage for the IC or equipment.

Note2 : The protective circuit function is provided to temporarily avoid abnormal state such as incorrect output

connection. But, there is no guarantee that the IC is not destroyed by the accident.

The protective function do not operate of the operation guarantee range. If the outputs are connected

incorrectly, IC destruction may occur when used outside of the operation guarantee range.

Note3 : External parts, such as the anti-oscillation part, may become necessary depending on the set condition.

Check their necessity for each set.
