Read through the following precautions before operating your MT50.

Safety precautions

• Make sure the AC adaptor's cord is not located in a position where it is
likely to be walked on or pinched by other equipment.
• Do not expose the MT50 to direct sunlight, extremes of temperature,
humidity, dust, vibration, or severe shocks.
• The ambient temperature where the MT50 is located should be between
10˚C and 35˚C (50˚F and 95˚F).
• Use only the AC adaptor supplied with the MT50. Do not use another
manufacturer's AC adaptor.
• The AC adaptor should be connected only to an AC power outlet of the
type stated on the AC adaptor or in this User's Guide.
• Before connecting the AC adaptor to the MT50, disconnect the adaptor
from the AC outlet. Always connect the AC adaptor to the MT50, then
plug the AC adaptor into the AC outlet.
• Grip the plug of the AC adaptor firmly when removing it from an AC
outlet. Do not pull the adaptor's cord.

• To reduce the risk of fire or electric shock, do not expose the MT50 to
rain or moisture.

MT50 powered on, but do not use it until the condensation has cleared.
Maintenance

moistened cloth. Stubborn marks can be removed using a mild deter-
gent. Do not use abrasive or solvent based cleaners such as alcohol and
benzine.
