Important Safeguards

1. Read, Follow, and Retain Instructions - All safety
and operating instructions should be read and
followed before operating the unit. Retain instructions
for future reference.

2. Heed Warnings - Adhere to all warnings on the unit
and in the operating instructions.

3. Attachments - Attachments not recommended by the
product manufacturer should not be used, as they
may cause hazards.

4. Installation Cautions - Do not place this unit on an
unstable stand, tripod, bracket, or mount. The unit
may fall, causing serious injury to a person and
serious damage to the unit. Use only manufacturer­recommended accessories, or those sold with the
product. Mount the unit per the manufacturer's
instructions. Appliance and cart combination should
be moved with care. Quick stops, excessive force, or
uneven surfaces may cause the appliance and cart
combination to overturn.

5. Cleaning - Unplug the unit from the outlet before
cleaning. Follow any instructions provided with the
unit. Generally, using a damp cloth for cleaning is
sufficient. Do not use liquid cleaners or aerosol
cleaners.

6. Servicing - Do not attempt to service this unit
yourself. Opening or removing covers may expose
you to dangerous voltage or other hazards. Refer all
servicing to qualified service personnel.

7. Damage Requiring Service - Unplug the unit from
the main AC power source and refer servicing to
qualified service personnel under the following
conditions:

• When the power supply cord or plug is damaged.

• If liquid has been spilled or an object has fallen

into the unit.

• If the unit has been exposed to water and/or

inclement weather (rain, snow, etc.).

• If the unit does not operate normally, when

following the operating instructions. Adjust only
those controls specified in the operating
instructions. Improper adjustment of other controls
may result in damage, and require extensive work
by a qualified technician to restore the unit to
normal operation.

• If the unit has been dropped or the cabinet

damaged.

• If the unit exhibits a distinct change in

performance, this indicates that service is needed.

8. Replacement Parts - When replacement parts are
required, the service technician should use
replacement parts specified by the manufacturer or
that have the same characteristics as the original part.
Unauthorized substitutions may result in fire,
electrical shock or other hazards.

9. Safety Check - Upon completion of servicing or
repairs to the unit, ask the service technician to
perform safety checks to ensure proper operating
condition.

10. Power Sources - Operate the unit only from the type
of power source indicated on the label. If unsure of
the type of power supply to use, contact your dealer
or local power company.

•For units intended to operate from battery power,

refer to the operating instructions.

•For units intended to operate with External Power

Supplies, use only the recommended approved
power supplies.

•For units intended to operate with a limited power

source, this power source must comply with
EN60950. Substitutions may damage the unit or
cause fire or shock.

•For units intended to operate at 24VAC, normal

input voltage is 24VAC. Voltage applied to the
unit's power input should not exceed 30VAC.
User-supplied wiring, from the 24VAC supply to
unit, must be in compliance with electrical codes
(Class 2 power levels). Do not ground the 24VAC
supply at the terminals or at the unit's power
supply terminals.

11. Coax Grounding - If an outside cable system is
connected to the unit, ensure that the cable system is
grounded. U.S.A. models only - Section 810 of the
National Electrical Code, ANSI/NFPA No.70,
provides information regarding proper grounding of
the mount and supporting structure, grounding of the
coax to a discharge unit, size of grounding
conductors, location of discharge unit, connection to
grounding electrodes, and requirements for the
grounding electrode.

12. Grounding - This unit is equipped with a 3-wire
grounding plug (a plug with a third pin, for
grounding). This safety feature allows the plug to fit
into a grounding power outlet only. If unable to insert
the plug into the outlet, contact an electrician to
arrange replacement of the obsolete outlet. Do not
defeat the safety purpose of the grounding plug.

•Outdoor equipment should only be connected to

the unit's inputs after this unit has had its grounding
plug connected to a grounded outlet or its ground
terminal properly connected to a ground source.

• The unit's input connectors must be disconnected

from outdoor equipment before disconnecting the
grounding plug or grounding terminal.

•Proper safety precautions such as grounding should

be followed for any outdoor device connected to
this unit.

13. Lightning - For added protection during a lightning
storm, or when this unit is left unattended and unused
for long periods of time, unplug the unit from the
wall outlet and disconnect the cable system. This will
prevent damage to the unit due to lightning and
power line surges.

For Indoor Product

1. Water and Moisture - Do not use this unit near
water - for example, in a wet basement, in an
unprotected outdoor installation or in any area
classified as a wet location.

2. Object and Liquid Entry - Never push objects of
any kind into this unit through openings, as they
may touch dangerous voltage points or short out
parts that could result in a fire or electrical shock.
Never spill liquid of any kind on the unit.

3. Power Cord and Power Cord Protection - For
units intended to operate with 230VAC, 50Hz,
the input and output power cord must comply
with the latest versions of IEC Publication 227 or
IEC Publication 245.
Power supply cords should be routed so they are
not likely to be walked on or pinched. Pay
particular attention to location of cords and plugs,
convenience receptacles, and the point of exit
from the appliance.

4. Overloading - Do not overload outlets and
extension cords; this can result in a risk of fire or
electrical shock.

For Outdoor Product

Power Lines - An outdoor system should not be
located in the vicinity of overhead power lines,
electric lights or power circuits, or where it may
contact such power lines or circuits. When
installing an outdoor system, extreme care should
be taken to keep from touching power lines or
circuits, as this contact might be fatal. U.S.A.
models only - refer to the National Electrical
Code Article 820 regarding installation of CATV
systems.

For Rack-mount Product

1. Ventilation - This unit should not be placed in a
built-in installation or rack, unless proper
ventilation is provided, or the manufacturer’s
instructions have been adhered to. The
equipment must not exceed its maximum
operating temperature requirements.

2. Mechanical Loading - Mounting of the
equipment in a rack shall be such that a
hazardous condition is not achieved due to
uneven mechanical loading.
