Precautions

•Do not place a container with liquid or small metal

objects on top of this unit. Liquid or metal objects

inside this unit are a ﬁre and electrical shock hazard.

•Do not allow water to enter this unit or allow the unit

to become wet. Fire or electrical shock may result.

•Connect this unit’s power cord only to an AC outlet of

the type stated in this Owner’s Manual or as marked

on the unit. Failure to do so is a ﬁre and electrical

shock hazard.

•Be sure to connect to an appropriate outlet with a pro-

tective grounding connection. Improper grounding

can result in electrical shock.

•Do not scratch, bend, twist, pull, or heat the power

cord. A damaged power cord is a ﬁre and electrical

shock hazard.

•Do not place heavy objects, including this unit, on top

of the power cord. A damaged power cord is a ﬁre and

electrical shock hazard. In particular, be careful not to

place heavy objects on a power cord covered by a car-

pet.

•If you notice any abnormality, such as smoke, odor, or

noise, or if a foreign object or liquid gets inside the

unit, turn it off immediately. Remove the power cord

from the AC outlet. Consult your dealer for repair.

Using the unit in this condition is a ﬁre and electrical

shock hazard.

• Should this unit/AC adapter/power supply be

dropped or the cabinet be damaged, turn the power

switch off, remove the power plug from the AC outlet,

and contact your dealer. If you continue using the unit

without heeding this instruction, ﬁre or electrical

shock may result.

•If the power cord is damaged (i.e., cut or a bare wire is

exposed), ask your dealer for a replacement. Using the

unit with a damaged power cord is a ﬁre and electrical

shock hazard.

•Do not remove the unit’s cover. You could receive an

electrical shock. If you think internal inspection,

maintenance, or repair is necessary, contact your

dealer.

•Do not modify the unit. Doing so is a ﬁre and electri-

cal shock hazard.

•When setting up the product, make sure that the AC

outlet you are using is easily accessible. If some trou-

ble or malfunction occurs, immediately turn off the

power switch and disconnect the plug from the outlet.

Even when the power switch is turned off, electricity is

still ﬂowing to the product at the minimum level.

When you are not using the product for a long time,

make sure to unplug the power cord from the wall AC

outlet.

•When rack-mounting the unit, allow enough free

space around the unit for normal ventilation. This

should be: 10 cm at the sides, 15 cm behind, and 30

cm above.

•For normal ventilation during use, remove the rear of

the rack or open a ventilation hole.

•If the airﬂow is not adequate, the unit will heat up

inside and may cause a ﬁre.

•This unit has ventilation holes at the top and bottom

to prevent the internal temperature rising too high.

Do not block them. Blocked ventilation holes are a ﬁre

hazard.

•Hold the power cord plug when disconnecting it from

an AC outlet. Never pull the cord. A damaged power

cord is a potential ﬁre and electrical shock hazard.

•Do not touch the power plug with wet hands. Doing

so is a potential electrical shock hazard.

•The digital circuits of this unit may induce a slight

noise into nearby radios and TVs. If noise occurs,

relocate the affected equipment.

Rack Mounting Caution

If the unit is rack mounted and transported regularly,

for example, when on a tour, we recommend that the

rear of the unit be supported by ﬁtting a pair metal

brackets, one each side. The following drawing pro-

vides the information necessary to make such brack-

ets.

Note that only one bracket is shown here and the

bracket for the other side must be bent in the opposite

direction.
