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 manufacturer-
recommended 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 or Polarization

- This unit may be

equipped with a polarized alternating current line
plug (a plug with one blade wider than the other).
This safety feature allows the plug to fit into the
power outlet in only one way. If unable to insert the
plug fully into the outlet, try reversing the plug. If the
plug still fails to fit, contact an electrician to arrange
replacement of the obsolete outlet. Do not defeat the
safety purpose of the polarized plug.
Alternately, this unit may be 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.

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.
