Protect the power cord from being walked on or pinched particularly at plugs, convenience receptacles and the point where they exit from the apparatus.
Only use attachments/accessories specified by the manufacturer.
Use only with the cart, stand, tripod, bracket or table specified by the manufacturer, or
sold with the apparatus. When a cart is used, use caution when moving the cart/
apparatus combination to avoid injury from tip-over.

liquids, such as vases, on the apparatus.
No naked flame sources, such as lighted candles, should be placed on the apparatus.
Ventilation should not be impeded by covering the ventilation openings with items such
as newspapers, table cloths, curtains etc.
THIS APPARATUS MUST BE EARTHED. Under no circumstances should the safety earth be
disconnected from the mains lead.
The mains supply disconnect device is the mains plug. It must remain accessible so as
to be readily operable when the apparatus is in use.

The following information is for reference only.
The wires in the mains lead are coloured in accordance with the following code:
Earth (Ground): Green and Yellow (US - Green/Yellow)
Neutral: Blue (US - White)
Live (Hot): Brown (US - Black)
As the colours of the wires in the mains lead may not correspond with the coloured
markings identifying the terminals in your plug, proceed as follows:
The wire which is coloured Green and Yellow must be connected to the terminal in
the plug which is marked with the letter E or by the earth symbol.
The wire which is coloured Blue must be connected to the terminal in the plug
which is marked with the letter N
The wire which is coloured Brown must be connected to the terminal in the plug
which is marked with the letter L
Ensure that these colour codes are followed carefully in the event of the plug being
changed
This unit is capable of operating over a range of mains voltages as marked on the rear
panel.
