• Explanation of Graphical Symbols

The lightning flash with arrowhead symbol, within an
equilateral triangle, is intended to alert you 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 you to the presence of important
operating and maintenance (servicing) instructions in
the literature accompanying the appliance.

Note to CATV system installer:

This reminder is provided to call the CATV system
installer’s attention to Article 820-40 of the NEC that
provides guidelines for proper grounding and, in
particular, specifies that the cable ground shall be
connected to the grounding system of the building, as
close to the point of cable entry as practical.

1 Read these instructions.
2 Keep these instructions.
3 Heed all warnings.
4 Follow all instructions.
5 Do not use this apparatus near water.
6 Clean only with dry cloth.
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 polarized or

grounding-type plug. A polarized plug has two blades with
one wider than the other. A grounding type plug has two
blades and a third grounding prong. The wide blade or the
third prong are 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.

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.
