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.

13 Unplug this apparatus during lightning  storms 

or when unused for long periods of time.

14  Refer all servicing to qualified service 

personnel. Servicing is required when the 
apparatus has been damaged in any way, 
such as power-supply cord or plug is 
damaged, liquid has been spilled or objects

To completely disconnect from AC mains,
disconnect the power supply cord from the AC
receptable.

The mains plug of the power supply shall
remain readily operable.

Do not install in a confined space.

inside.

Caution:

You are cautioned that any change or
modifications not expressly approved in this
manual could void your authority to operate this
equipment.

To reduce the risk of fire or electrical shock,
do not expose this equipment to dripping or
splashing and ensure that no objects filled
with liquids, such as vases, are placed on the
equipment.

This apparatus must be earthed.

Use a three wire grounding type line cord 
like the one supplied with the product.

Be advised that different operating voltages
require the use of different types of line 
cord and attachment plugs.

Check the voltage in your area and use the 
correct type. See table below:

age" within the product's enclosure that may be of
sufficient magnitude to constitute a risk of 
electric shock to persons.

The exclamation point within an

equilateral triangle is intended to alert the
