This processor is a mains-powered device (90–240 V AC), read the operating manual completely before use and keep it for future reference. To reduce the risk of fire or electric shock, do not expose the unit to rain, moisture, dripping, or splashing, and never place liquids on or near it; do not use it near water. Do not block the ventilation openings, when rack-mounting, leave venting space between units and ensure the rack provides adequate airflow, and keep the unit away from radiators, amplifiers, and other heat sources. Do not defeat the safety purpose of the grounding plug, and protect the power cord from being walked on or pinched, particularly at the plug and where it exits the unit. Replace the fuse only with the specified type (T2.5A, 250 V). Place the unit only on a stable surface or in a secure rack. Unplug it before cleaning (dry cloth only), during lightning storms, and when unused for long periods. Use only accessories specified by the manufacturer. The unit contains no user-serviceable parts, refer all servicing to qualified personnel, especially if the power cord or plug is damaged, liquid has entered the unit, it has been exposed to rain or moisture, dropped, or does not operate normally.
