WARRANTY
Phoenix guarantees, that every new product purchased at an authorized distributor is free of
assembly and material and material defects.
During the guarantee, the purchaser is entitled to repairs free of charge in cases ivolving
assembly defects.
Defects reported during the time of the guarantee will be repaired by an authorized dealer
free of charge within 21 days from the date that the equipment is delivered for repair - the time

The guarantee is extended by the time it takes to complete reparations of the product.
Under the guarantee, those repairs for which instructions are given in the manual will not
be cover, and are the sole responsiblity of the owner’s time and cost. For example, the installation
of equipment, the testing, maintenance (especially the cleaning of the filter), and interchanging
the fuses. All of the afore mentioned repairs can be made by the dealer at the customer’s own cost.
Guarantee does not cover:
- Mechanical, chemical, and thermal damages inflicted on the equipment.
- Damages and defects caused by wrongful installation, usage, storage, and maintenance.
- Damages caused by repairs and changes to the equipment made by the customer or other
unauthorized persons.
- Damages attributed to acts of god.
The owner provides damaged equipment for repairs or sale at his or her time and cost, preferably

SAFETY TIPS
EQUIPMENT SETUP
Avoid setting up the equipment areas:
- subject to direct sunlight
- exposed to high temperatures
- exposed to moisture
- subject to high vibrations
- on an uneven surface
Non compliance can lead to damaging the outside frame and/ or other parts which could shorten the allotted time of operation.
VENTILATION
Install the equipment in the area with proper ventilation - with a distance of at
least 10cm from the rear of the device to the wall. Remember that objects such
as curtains should not cover the ventilation openings.
PLACING OBJECTS ON TOP OF THE AMPLIFIER
Do not place heavy object on top of the amplifier or on the electrical cord.
Such actions could cause the top plate to be permanently deformed or the electrical
cord to be severed.
VOLTAGE
The equipment cannot be plugged into a DC socket. Make sure the parameters
of the socket are known.
ELECTRICAL CORD
When inserting the electrical cord into the socket, hold the plug firmly and make
sure it is propely placed into the socket. Never attempt to touch the socket with
moist hands.
Avoid cutting, scratching, over bending, stretching, and folding the electrical cord.
Such actions could cause a fire or electrical shock.
When unplugging the cord do not pull the wire because an electrical shock could
result.
FOREIGN OBJECTS
- Do not allow objects such as needles, coins, screws, etc to accidentally fall into
the equipment through the ventilation openings. The result could be serious
damage to the amplifier and electrical shock.
- At no time should water or any other liquid to be spilled on or into the equipment
due to the high risk of fire or shock.
- Avoid using any aerosol sprays around the equipment.
SERVICE
Never try to take apart, fix or repair the equipment. If problems arise at time of operation
(interrupted sound, signals do not light up, traces of smoke arise, etc.) Immediately turn off the
amplifier and contact an authorized dealer. If the equipment will not be used for an extented period
of time , unplugged the amplifier from the outlet.
MAINTENANCE
Clean the frame, the main frame, and the regulator witch a soft moist towel, lightly covered
with a gentle detergent. Do not use any abrasive materials or detergents. Do not use any solvent
such as alcohol or gasoline.
