Notes For Service Engineers - Medion NOTEBOOK COMPUTER Manual

• Before opening the housing, disconnect the Notebook from all
power sources and remove any connecting cables. If the
Notebook has not been disconnected from the power outlet
before being opened, there is a danger of severe electric
shock. There is also a risk of damage to the components.
• Internal components of the Notebook may be damaged by
electrostatic discharge (ESD). Perform system upgrades
and changes in an ESD-protected work area. If no such
work area is available, wear an antistatic wrist strap or touch
a highly conductive metal object. Your service center can repair
damage sustained by inappropriate handling for a fee.
• Use only original spare parts.
CAUTION: The CMOS lithium batteries cannot tolerate intense
pressure, high temperatures or fire. Keep away from children!
Danger of explosion if replaced incorrectly. Only replace with a
compatible type (CR2032) as recommended by the manufac-
turer. Lithium-Batteries are hazardous waste and need to be
disposed of properly. If necessary, we will take back your used
CMOS lithium battery.
Notes on Laser Radiation :
Laser devices of Laser Class 1 to Laser Class 3b may be used in
the Notebook. Where the Notebook housing remains closed, the
device meets the requirements of Laser Class 1. By opening
the Notebook housing you will gain access to laser devices of
up to Laser Class 3b.
• The CD-ROM/CD-RW/DVD/DVD-RW drive contains no user-
serviceable parts. Only the manufacturer should perform
repairs to the CD-ROM/CD-RW/DVD/DVD-RW drives.
When removing and/or opening laser devices, the following
guidelines must be observed:
• DO NOT look into the laser beam, even while wearing opti-
cal protection.
• DO NOT allow yourself to be exposed to the laser beam.
Avoid exposure of the eyes or skin to direct or stray
radiation.
