switch off the power, unplug the power cord and contact the nearest authorized
service center.

2. Never remove the bottom cover

Do not remove the bottom cover of this product. This product produces high level
voltage and current that can be “lethal”. Touching any high voltage parts inside
the unit can result in electric shock and/or cause damage to the unit. Do not
tamper with any component or part inside the unit. Even with the power turned off,
high level of electric charge can remain in the energy storing capacitors for an
extended period of time up to months. Any possible adjustment inside the chassis
or service required should to be referred to authorized Audio Space Acoustic
Laboratory Ltd. dealer or other qualified electronics technician.

heavy dust, intense heat, high humidity, kitchen smoke, etc., as these may cause
the product to malfunction.

4. Select a safe and well-ventilated location
This product contains vacuum tubes (with glass container) that are fragile and
breakable. During operation, the vacuum tubes will generate sufficient heat that
can burn to the touch. Therefore, it should be kept away from children and house
pets. The unit should be placed in a well ventilated area to allow heat to escape
freely. Insufficient air flow may cause the unit to overheat which may result in
malfunction or in some cases catch on fire.

• Do not place this product in a confined space or cabinet with poor ventilation.

5. Handling the power Cord

Using a damaged power cord or one with bare wires exposed is a fire hazard and
may result in electric shock. Always observe the following guidelines:

• When unplugging from the AC outlet, never pull on the cord, always grip the

plug when unplugging the power cord.

• Never place this product itself, furniture, rugs or other heavy objects on the

power cord.

• If the power cord must pass near a heater, make sure the cord is far enough

from the heater so as to prevent power cord from melting from direct heat or
come into contact with the heater accidentally.

• If the power cord is damaged, replace it before operating the unit again.

6. When the product will not be used for an extended period of time

If you go away on holidays or otherwise will be absent for a long period of time,

the electrical outlet that is connected to the unit via the power cord.

7. Keep the unit away from any moisture

Do not place any objects containing water or other liquids near or on this product.
If liquid comes into contact with this unit, it can cause malfunction, electrical
shock or fire. If liquid should get inside the chassis, unplug the power cord from
the AC mains at once and contact the nearest authorized service center or
qualified electronics technician.

8. Never insert objects into this product

Do not insert or drop any object of metallic, inflammable, or other material into
this product through the air vents, as this can cause damage, electrical shock, or
possibly fire.

9. Keep the product away from strong magnetic object
Operating this product in or near strong magnetic field will affect the performance
of this product.
