• Never operate the inverter from any power source other than a 12 volt
DC battery.
• The inverter is designed to be connected to the cigarette lighter socket
with the 12 volt power plug. Do not modify the power plug.
• While connecting the inverter to the power source, make certain the
inverter is far away from any potential source of flammable fumes or gases.
• Do not expose the inverter to rain or moisture.
• Make certain the power consumption of the appliance or equipment you
wish to operate is compatible with the capacity of the inverter. Do not
exceed 85 watts.
• When attempting to operate battery chargers, monitor the temperature of
the battery charger for approximately 10 minutes. If the battery charger or
inverter becomes abnormally warm, disconnect it from the inverter
immediately.
• Use only 10 amp Glass type fuse.
• Always disconnect the inverter when not in use.
• Avoid placing the inverter near sources of heat or in direct sunlight.
• While in use, make sure the inverter is properly ventilated.
• When operating the inverter with an automobile or marine battery, start
