Note that this unit will be seriously damaged if this setting is not made correctly. (There is no voltage selector for some countries, the correct voltage is already set.) 2. Before Repair and Adjustment Disconnect AC power, discharge Power Supply Capacitors C571-C574 and C581 through a 10 5W resistor to ground.

AC mains lead (For GN only) AM Loop antenna Power plug adaptor (for GC only) 5. Handling 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).
Page 6
- 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 conductive 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.

6. Precaution of Laser Diode Caution : This product utilizes a laser diode with the unit turned "ON", invisible laser radiation is emitted from the pick up lens. / Wavelength : 780 nm / Maximum output radiation power from pick up : 100 W/VDE / Laser radiation from pick up unit is safety level, but be sure the followings:...
Page 8
Wellenlänge : 780nm / Maximale Strahlungsleistung der Lasereinheit :100 W/VDE / Die Strahlung an der Lasereinheit ist ungefährlich, wenn folgende Punkte beachtet werden: 1. Die Lasereinheit nicht zerlegen, da die Strahlung an der freigelegten Laserdiode gefährlich ist. 2. Den werkseitig justierten Einstellregler der Lasereinhit nicht verstellen.
