1. Safety Precautions for those who Service this Unit.
· Follow the adjustment steps (see pages 192 through 255)in the service manual when servicing this unit. When check
-
ing or adjusting the emitting power of the laser diode exercise caution in order to get safe, reliable results.
Caution:
1. During repair or tests, minimum distance of 13cm from the focus lens must be kept.
2. During repair or tests, do not view laser beam for 10 seconds or longer.
2. The triangular label is attached to the mechanism
unit frame.

LASER PRODUCT
WARNING!
The AEL (accessible emission level )of the laser power output is less than CLASS 1
but the laser component is capable of emitting radiation exceeding the limit for
CLASS 1.
A specially instructed person should do servicing operation of the apparatus.
Laser diode characteristics
Wave length:
DVD:640~660nm
CD:770~810nm
Maximum output:2.48mw(Emitting period :9sec.)
DVD:705
µw(Emitting period : unlimited)
Additionla Laser Caution
Transistors Q1101 and Q1102 in PCB drive the laser diodes for DVD and CD
respectively. When Q1101 or Q1102 is shorted between their terminals,
the laser diodes for DVD or CD will radiate beam. If the top cover is removed
with no disc loaded while such short-circuit is continued, the naked eyes may
be exposed to the laser beam.

DVD MECHANISM MODULE section precaution
1. Before disassembling the unit, be sure to turn off the power. Unplugging and plugging the connectors during
power-on mode may damage the ICs inside the unit.
2. To protect the pickup unit from electrostatic discharge during servicing, take an appropriate treatment
(shorting-solder) by referring to "the DISASSEMBLY" on page 262.
3. After replacing the pickup unit, be sure to check the grating. (See p.196.)
4. During disassembly, be sure to turn the power off since an internal IC might be destroyed when a connector is
plugged or unplugged.
NAVIGATION UNIT section precaution
1. Inverter for LCD back light becomes a high voltage.
2. When inspecting the touch panel, use something thin with a round tip such as the touch pen. Furthermore,
do not apply excessive force to the touch panel.
3. Since this product does not have OSD IC, OSD for adjustment is displayed by using GGF1416 and GGF1463
at the time of monitor adjustment. As you will find lands for 14 pins with 0.8mm pitch at the left top part of
the monitor board, directly solder a flexible PCB of GGD1323 for adjustment. As GGD1322 is not used, be
careful not to short the terminal.
4. The region code determination at the time of DVD hardware change is made by the destination (UC: Region 1,
EW: Region 2) of the car control unit.
5. If you reconnected the Hide-away unit, press the RESET button.
