Verify Line Voltage Before Use
Your AVR21EN has been designed for use with 120-volt AC current.
Connection to a line voltage other than that for which it is intended
can create a safety and fire hazard, and may damage the unit. If
you have any questions about the voltage requirements for your
specific model, or about the line voltage in your area, contact your
selling dealer before plugging the unit into a wall outlet.
Do Not Use Extension Cords
To avoid safety hazards, use only the power cord attached to your
unit. We do not recommend that extension cords be used with this
product. As with all electrical devices, do not run power cords
under rugs or carpets, or place heavy objects on them. Damaged
power cords should be replaced immediately by an authorized
service center with a cord meeting factory specifications.
Handle the AC Power Cord Gently
When disconnecting the power cord from an AC outlet, always pull the
plug; never pull the cord. If you intend to refrain from using the unit for
any considerable length of time, disconnect the plug from the AC outlet.
Do Not Open the Cabinet
There are no user-serviceable components inside this product.
Opening the cabinet may present a shock hazard, and any modifi-
cation to the product will void your warranty. If water or any metal
object such as a paper clip, wire or a staple accidentally falls inside
the unit, disconnect it from the AC power source immediately, and
consult an authorized service center.
CATV or Antenna Grounding
If an outside antenna or cable system is connected to this product,
be certain that it is grounded so as to provide some protection
against voltage surges and static charges. Section 810 of the
National Electrical Code, ANSI/NFPA No. 70-1984, provides informa-
tion with respect to proper grounding of the mast and supporting
structure, grounding of the lead-in wire to an antenna discharge
unit, size of grounding conductors, location of antenna discharge
unit, connection to grounding electrodes and requirements of the
grounding electrode.
Note to CATV System Installer:
This reminder is provided to call the CATV (cable TV) system
installer’s attention to article 820-40 of the NEC which 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 possible.
Installation Location
I To ensure proper operation and to avoid any potential safety
hazards, place the unit on a firm and level surface. When placing
the unit on a shelf, be certain that the shelf and any mounting
hardware can support the weight of the product.
I Make certain that proper space is provided both above
and below the unit for ventilation. If this product will be
installed in a cabinet or other enclosed area, make certain
that there is sufficient air movement within the cabinet.
Under some circumstances, a fan may be required.
I Do not place the unit directly on a carpeted surface.
I Avoid installation in extremely hot or cold locations, or in an
area that is exposed to direct sunlight or heating equipment.
I Avoid moist or humid locations.
I Do not obstruct the ventilation slots on the top of the unit, or
place objects directly over them.
I There is the remote possibility that the rubber padding on the
bottom of the unit’s feet may leave marks on certain wood or
veneer materials. Use caution when placing the unit on soft
woods or other materials that may be damaged by heat or
heavy objects.
Cleaning
When the unit gets dirty, wipe it with a clean, soft, dry cloth.
NEVER use benzene, aerosol cleaners, thinner, alcohol or any other
volatile cleaning agent. Do not use abrasive cleaners, as they may
damage the finish of metal parts. Avoid spraying insecticide near
the unit.
Moving the Unit
Before moving the unit, be certain to disconnect any interconnec-
tion cords with other components, and make certain that you dis-
connect the unit from the AC outlet.
