@ Handing Precautions for Traverse Deck
The laser diode in the traverse deck (optical pickup) may break down due to potential difference caused by static electricity of clothes or human body.
So, be careful of electrostatic breakdown during repair of the traverse deck (optical pickup).
@ Handling of traverse deck (optical pickup)
1. Do not subject the traverse deck (optical pickup) to static electricity
as it is extremely sensitive to electrical shock.
2. To prevent the breakdown of the laser diode, an anti-static shorting
pin is inserted into the flexible board (FPC board).
When removing or connecting the short pin, finish the job in as short
time as possible.
3. Take care not to apply excessive stress to the flexible board (FPC
board).
4. Do not turn the variable resistor (laser power adjustment). It has al-
ready been adjusted.
® Grounding for electrostatic breakdown prevention
1. Human body grounding
Use the anti-static wrist strap to discharge the static electricity from
your body.
2. Work table grounding
Put a conducive material (sheet) or steel sheet on the area where the
traverse deck (optical pickup) is placed, and ground the sheet.
Caution:
The static electricity of your clothes will not be grounded through the
wrist strap. So, take care not to let your clothes touch the traverse deck
(optical pickup).
m@ Precaution of Laser Diode
CAUTION:
Wave length: 780 nm
FPC po
Lens (Do not touch) ;
(Handle it carefully)
Be sure to short this portion
(Use the shorting pin or clip)
Iron plate or some metals to

This product utilizes a laser diode with the unit turned “on”, invisible laser radiation is emitted from the pick up lens.
Maximum output radiation power from pick up: 100 uW/VDE
Laser radiation from the pick up unit is safety level, but be sure the followings:
1. Do not disassemble the pick up unit, since radiation from exposed laser diode is dangerous.
2. Do not adjust the variable resistor on the pick up unit. It was already adjusted.
3. Do not lock at the focus lens using optical instruments.
4. Recommend not to lock at pick up lens for a long time.
ACHTUNG:

Dieses Produkt enthalt eine Laserdiode. Im eingeschalteten Zustand wird unsichtbare Laserstrahlung von der Lasereinheit
Maximale Strahlungsleistung der Lasereinheit: 100WW/VDE
Die Strahlung an der Lasereinheit ist ungefahrlich, wenn folgende Punkte beachtet werden:
1. Die Lasereinheit nicht zerlegen, da die Strahlung an der freigelegten Laserdiode gefahrlich ist.
2. Den werksseitig justierten Einstellregler der Lasereinheit nicht verstellen.
3. Nicht mit optischen Instrumenten in die Fokussierlinse blicken.
4, Nicht Uber langere Zeit in die Fokussierlinse blicken.

mCaution for AC Mains Lead (For United Kingdom)
(“EB” area code model only)
For your safety, please read the following text care-
frilly
runny.
This appliance is supplied with a moulded three pin
mains plug for your safety and convenience.
A 5-ampere fuse is fitted in this plug. :
Should the fuse need to be replaced please ensure that
the replacement fuse has a rating of 5-ampere and that
itis approved by ASTA or BS! to BS1362.
Check for the ASTA mark @> or the BSI mark Y on
the body of the fuse.
If the plug contains a removable fuse cover you must
ensure that it is refitted when the fuse is replaced.
If you lose the fuse cover the plug must not be used
until a replacement cover is obtained.
A replacement fuse cover can be purchased from your
local dealer.
CAUTION!
IF THE FITTED MOULDED PLUG IS UNSUIT-
ABLE FOR THE SOCKET OUTLET IN YOUR
HOME THEN THE FUSE SHOULD BE RE-
MOVED AND THE PLUG CUT OFF AND DIS-
POSED OF SAFELY.
THERE IS A DANGER OF SEVERE ELECTRI-
CAL SHOCK IF THE CUT OFF PLUG IS IN-
SERTED INTO ANY 13-AMPERE SOCKET.
If a new plug is to be fitted please observe the wiring
code as shown below.
If in any doubt please consult a qualified electrician.
IMPORTANT
If the socket outlets in the home are not suitable for the
plug supplied with this appliance it should be cut off
and an appropriate three pin plug fitted.
The wires in this mains lead are coloured in accor-
dance with the following code:
Blue: Neutral
Brown: Live
Do not connect either wire to the earth terminal in the
plug which is marked by the letter “E” or by the safety
earth symbol — or coloured green or green-and-
yellow.
As the colours of the wires in the mains lead of this
apparatus may not correspond with the coloured mark-
ings identifying the terminals in your plug proceed as
follows. The wire which is coloured BLUE must be con-
nected to the terminal which is marked with the letter N
or coloured BLACK.
The wire which is coloured BROWN must be con-
nected to the terminal which is marked with the letter L
or coloured RED.
Before use
Remove the connector cover as follows.
