DC Connection
NOTICE: Risk of damage!
For protection of the appliance, the DC cable supplied includes a fuse inside the plug. Do not remove the fuse from the DC plug. Only use the DC cable supplied by the manufacturer.

• Plug the DC cable into DC power supply inlet of the appliance. Connect the DC cable to the DC power supply outlet.

AC Connection

• Plug the DC cable into DC power supply inlet of the appliance.
• Connect the DC cable to the cigarette lighter socket of an AC adaptor (AC adaptor is not included).
• Connect the AC cable of the AC adaptor to the AC power supply outlet.

NOTICE: Risk of damage!

• Only use the AC adaptor supplied by the manufacturer.
• Never touch plugs and switches with wet hands or if you are standing on a wet surface.
• If you are operating the appliance on board of a boat from a 120V power supply, you must install a residual current circuit breaker between the 120V AC power supply and the appliance. Ask for advice from a qualified technician.

How to Use

Switch-On
NOTICE! Risk of overheating!
Ensure at all time that the appliance is used in a well-ventilated area so that the heat generated during the operation can dissipate. Ensure that the vent is not blocked and the appliance is far away from walls and other objects so that the air can circulate.

• Place the appliance on a firm surface.
• Close the lid of the appliance.
• Switch on the appliance.

NOTICE: Risk of excessively low temperature!
