prevent overheating and any risk of fire.

Keep the product away from direct heat sources such as radiators and 

out of direct sunlight to prevent any risk of overheating.

The power supply required for this product is 220-240 VAC, 50/60 Hz. 

(For any DC powered product, the figures are 9.6-31.2VDC, 4-1.8A.) 

Refer to your product's rating label on the machine for full power rating 

details. Ensure that you have a suitable power supply before connecting

connect to an earthed socket. Do not attempt to defeat the earthing or 

there is a risk of fire or shock.

If using an extension cable or power strip ensure that the total current 

rating (amperes) of all connected equipment is less than the maximum 

rating of the extension cable, power strip or wall outlet. If the product is 

already supplied with a fitted power strip then no additional power strip 

or extension cable should be used to connect to the mains wall outlet.

accessible at all times and not obstructed.

Use only the power cable supplied. Using a power cable not intended for 

this product may lead to fire or electric shock.

To avoid risk of fire and electric shock, do not use the power cable 

supplied with this product for any other electrical equipment.

If you do not connect the power cord or any other cables only as
