Precautions

—For safe operation—

WARNING

Installation

●Connect this unit’s AC power adaptor 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.

●Do not allow water to enter this unit or allow the unit to become wet. Fire or electrical shock may result.

●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 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 carpet.

Operation

●Do not scratch, bend, twist, pull, or heat the power cord. A dam- aged 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 electrical shock hazard.

●If lightning begins to occur, turn off the power switch of the unit as soon as possible, and unplug the power plug from the electri- cal outlet.

●If there is a possibility of lightning, do not touch the power plug if it is still connected. Doing so may be an electrical shock haz- ard.

●Use only the included AC power adaptor (PA-20) for this unit. Using other types may be a fire and electrical shock hazard.

In case an abnormality occurs during operation

●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.

●Should this unit and AC adaptor 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 you notice any abnormality, such as smoke, odor, or noise, or if a foreign object or liquid gets inside the unit, turn it off imme- diately. Remove the power plug from the AC outlet. Consult your dealer for repair. Using the unit in this condition is a fire and electrical shock hazard.

CAUTION

Installation

●Keep this unit away from the following locations:

-Locations exposed to oil splashes or steam, such as near cook- ing 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 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.

●To relocate the unit, turn the power switch off, remove the power plug from the AC outlet, and remove all connecting cables. Dam- aged cables may cause fire or electrical shock.

Operation

●Do not cover or wrap the AC power adaptor with a cloth or blan- ket. Heat may build up under the cloth or blanket, melting the case, or causing fire. Use only in a well-ventilated environment.

●If you know you will not use this unit for a log period of time, such as when going on vacation, remove the power plug from the AC outlet. Leaving it connected is a potential fire hazard.
