Safety

Explanation of graphical symbols

The lightning wash with arrowhead symbol within an equilateral triangle is intended to alert the user to the
presence of uninsulated "dangerous voltage" 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 user to the presence of important
operating and maintenance instructions in the literature accompanying the product.

7.

Do not block any ventilation openings. Install in accordance with the manufacturer's instructions.

8.

Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including amplifiers)

that produce heat.

9.

Do not defeat the safety purpose of the grounding-type plug. A grounding-type plug has two blades and a third

grounding prong. The third prong is provided for your safety. If the provided plug does not fit into your outlet, consult
an electrician for replacement of the obsolete outlet.

10.

Protect the power cord from being walked on or pinched particularly at plugs, convenience receptacles, and the point

where they exit from the apparatus.

11.

Only use attachments/accessories specified by the manufacturer.

12.

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.

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 have fallen into the apparatus,
the apparatus has been exposed to rain or moisture, does not operate normally, or has been dropped.

15

. WARNING: To reduce the risk of fire or electric shock, this apparatus should not be exposed to rain or moisture and

objects filled with liquids, such as vases, should not be placed on this apparatus.

Additional important safety instructions

Verify the electrical conformity and compatibility of the mains supply.

Only connect the product to an AC power outlet rated 100-240 V, 50-60 Hz, with the following current values:

100-120 V: 20 A
200-240 V: 20 A

WARNING: The product is of CLASS 1 construction and shall be connected to a mains socket outlet with
a protective connection to earth.
