IMPORTANT SAFETY INSTRUCTIONS
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.
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 a 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.
WARNING: Avoid electric shock and fire hazard! If this product connects to coaxial
cable wiring, be sure the cable system is grounded (earthed). Grounding provides
some protection against voltage surges and built-up static charges.
Power Source Warning
A label on this product indicates the correct power source for this product. Operate this product only
from an electrical outlet with the voltage and frequency indicated on the product label. If you are
uncertain of the type of power supply to your home or business, consult your service provider or your
local power company.

WARNING: Avoid electric shock and fire hazard! Do not overload AC mains, outlets,
extension cords, or integral convenience receptacles. For products that require battery
power or other power sources to operate them, refer to the operating instructions for
those products.
WARNING: There is danger of explosion if the battery is mishandled or incorrectly
replaced. Replace only with the same type of battery. Do not disassemble it or attempt
to recharge it outside the system. Do not crush, puncture, dispose of in fire, short the
external contacts, or expose to water or other liquids. Dispose of the battery in
accordance with local regulations and instructions from your service provider.
Protect the Product from Lightning
In addition to disconnecting the AC power from the wall outlet, disconnect the signal inputs.
Verify the Power Source from the On/Off Power Light
When the on/off power light is not illuminated, the apparatus may still be connected to the power
source. The light may go out when the apparatus is turned off, regardless of whether it is still plugged
into an AC power source.
Eliminate AC Mains Overloads
