I. Safety instructions

When using electric products, basic precautions should always
be followed, including the following:

1. Read Instructions – All the safety and operating instructions
should be read before the appliance is operated.

2. Retain Instructions – The safety and operating instructions
should be retained for future reference.

3. Heed Warnings – Adhere to all warnings on the appliance
and in the operating instructions.

4. Follow Instructions – All operating and use instructions
should be followed.

5. Water and Moisture – The appliance should not be used near
water-for example, near a bathtub, wash-bowl, kitchen sink,
laundry tub, in a wet basement, or near a swimming pool, etc.

6. Carts and Stands – The appliance should be used only with
a cart or stand that is recommended by the
manufacturer. An appliance and cart
combination should be moved with
care. Quick stops, excessive force,
and uneven surfaces may cause the
appliance and cart combination to
overturn.

7. Wall or Ceiling Mounting – The appliance should be mounted
to a wall or ceiling only as recommended by the manufacturer.

8. Ventilation – The appliance should be situated so that its lo
cation or position does not interfere with its proper ventilation.
For example, the appliance should not be situated on a bed,
sofa, rug or similar surface that may block the ventilation open­ings; or placed in a built-in installation, such as a bookcase or
cabinet that may impede the flow of air through the ventilation
openings.

9. Heat – The appliance should be situated away from heat
sources such as radiators, heat registers, stoves, or other ap
pliance (including amplifier) which produce heat.

10. Nonuse Periods – The power cord of the appliance should

be unplugged from the outlet when left unused for a long pe
riod of time.

11. Power Sources – The appliance should be connected to

a power supply only of the type described in the operating
instructions or as marked on the appliance.

12. Power Lines – An outdoor antenna should be located away

from power lines.

13. Power Cord Protection – Power-supply cords should be

routed so that they are not likely to be walked on or pinched
by items placed upon or against them, paying particular atten­tion to cords, at plugs, convenience receptacles, and the point
where they exit from the appliance.

14. Power requirements for multi voltage (not for all mod

els) – Before connecting the power cord, make sure that the

voltage selector on the rear panel is set to the correct voltage
for you area. If not, please set it correctly.

15. Load – For protecting the appliance from being damaged, rated

load while is printed on the appliance or is explained in opera­tion instruction, that should be connected to the speaker out­put of the appliance. Never short circuit the speaker output of
the appliance when the appliance is working.

16. Object and Liquid Entry – Care should be taken so that

objects do not fall and liquids are not spilled into the enclosure
through openings.

17. Cleaning – Unplug the appliance from the wall outlet before

cleaning. Do not use liquid cleaners or aerosol cleaner. Use a
damp cloth for cleaning.

18. Make your contribution to protect the environment –

Used batteries with the ISO symbol for recycling as well as
small accumulators (rechargeable batteries),
mini-batteries (cells) and starter
batteries should not be thrown into
the garbage can. Please leave them
at an appropriate depot.

Portable cart warning

19. Overloading – Do not overload wall outlets and extension

cords as this can result in a risk of fire or electric shock.

20. Damage Requiring Service – Unplug this appliance from the
wall outlet and refer servicing to qualified service personnel
under the following conditions:
a). The power-supply cord or the plug has been damaged;
b). Objects have been fallen, or liquid has been spilled into

the appliance;
c) . The appliance has been exposed to rain;
d) . The appliance does not appear to operate normally or ex-

hibits a marked change in performance;
e). The appliance has been dropped, or the enclosure dam

aged.

WARNING
TO REDUCE THE RISK OF FIRE OR ELECTRIC SHOCK, DO
NOT EXPOSE THIS APPLIANCE TO RAIN OR MOISTURE.

CAUTION

RISK OF ELECTRIC SHOCK

DO NOT OPEN

CAUTION
TO REDUCE THE RISK OF ELECTRIC SHOCK, DO NOT
REMOVE COVER (OR BACK). NO USER SERVICEABLE
P ARTS INSIDE. REFER SERVICING T O QUALIFIED SERVICE
PERSONNEL.

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

CLASS 1 LASER PRODUCT

This product contains a low power laser device. To ensure
continued safety, do not remove any covers or attempt to gain
access to the inside of the product. Refer any servicing to qualified
personnel.
