Unplug the power cord before removing the system chassis cover for installation or servic-
ing. After installation or servicing, cover the system chassis before plugging the power cord.
•
Danger of explosion if battery incorrectly replaced.
•
Replace only with the same or equivalent type recommend by the manufacturer.
•
Dispose of used batteries according to local ordinance.
• Keep this system away from humidity.
• Place the system on a stable surface. Dropping it or letting it fall may cause damage.
• The openings on the system are for air ventilation to protect the system from overheating.
DO NOT COVER THE OPENINGS.
• Place the power cord in such a way that it will not be stepped on. Do not place anything on
top of the power cord. Use a power cord that has been approved for use with the system
and that it matches the voltage and current marked on the system’s electrical range label.
• If the system will not be used for a long time, disconnect it from the power source to avoid
damage by transient overvoltage.
• If one of the following occurs, consult a service personnel:
- The power cord or plug is damaged.
- Liquid has penetrated the system.
- The system has been exposed to moisture.
- The system is not working properly.
- The system dropped or is damaged.
- The system has obvious signs of breakage.
• The unit uses a three-wire ground cable which is equipped with a third pin to ground the
unit and prevent electric shock. Do not defeat the purpose of this pin. If your outlet does
not support this kind of plug, contact your electrician to replace the outlet.
• Disconnect the system from the DC outlet before cleaning. Use a damp cloth. Do not use
liquid or spray detergents for cleaning.
