Cautions
Installation
• Keep this unit away from the following locations:
— Locations exposed to oil splashes or steam, such as near cooking stoves, humidifiers, etc.
— Unstable surfaces, such as a wobbly table or slope.
— Locations exposed to excessive heat, such as inside a car with all the windows closed, or
places that receive direct sunlight.
— Locations subject to excessive humidity or dust accumulation.
• 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.
• This unit has ventilation holes to prevent the internal temperature from rising too high. Do
not block them. Blocked ventilation holes are a fire hazard. In particular, do not operate the
unit while it’s on its side, is upside down, or while it’s covered with a cloth or dust sheet.
• When installing the unit in a rack, you must use the rack-mounting screw holes at the rear
in addition to those on the front panel.
• When rack-mounting or stacking several units, always leave at least 1U (i.e., about 4.5 cm)
of free space above and below the unit for normal ventilation. If the airflow is restricted, the
unit may overheat, which could cause a fire.
• To relocate the unit, turn the power switch off, remove the power plug from the AC outlet,
and remove all connecting cables. Damaged cables may cause fire or electrical shock.
• This unit is equipped with a dedicated ground connection to prevent electrical shock.
Before connecting the power plug to an AC outlet, be sure to ground the unit. If the power
cord has a three-pin plug, it will provide sufficient grounding so long as the AC outlet is
grounded correctly.
Operation
• If you know you will not use this unit for a long period of time, such as when going on vaca-
tion, remove the power plug from the AC outlet. Leaving it connected is a potential fire haz-
ard.
Maintenance
• To prevent electrical shock when cleaning the unit, remove the power plug from the AC out-
let.
