electrical shock hazard.

• Connect the supplied AC power cord only to an AC outlet of the type stated in this

Owner’s

Manual

or as marked on the main unit. Failure to do so is a ﬁre and electrical shock hazard.

• Do not plug several devices into the same AC outlet. This can overload the AC outlet, and

can be a ﬁre and electrical shock hazard. It may also affect the performance of some devices.

• Do not place heavy objects on the power cord. A damaged power cord is a potential ﬁre and

electrical shock hazard.

• If the power cord is damaged (i.e., cut or a bare wire is exposed), ask your dealer for a

replacement. Using MD4 in this condition is a ﬁre and shock hazard.

• Hold the AC power cord plug when disconnecting from an AC outlet. Never pull the cord.

Damaging the power cord in this way is a potential ﬁre and electrical shock hazard.

• Do not place small metal objects on top of MD4. Metal objects inside MD4 are a ﬁre and

electrical shock hazard.

• Do not block the MD4 ventilation holes. MD4 has ventilation holes at the rear to prevent

the internal temperature from rising. Blocked ventilation holes are a ﬁre hazard.

• Do not try to modify MD4. This could be a ﬁre and electrical shock hazard.

• MD4 operating temperature is between 5˚C and 35˚C (41˚F and 95˚F).

• Handle MD DATA discs with care.

• If you notice any abnormality—such as smoke, odor, or noise—turn off MD4 immediately.

Remove the AC power cord from the AC outlet. Conﬁrm that the abnormality is no longer

present. Consult your dealer for repair. Using MD4 in this condition is a ﬁre and shock

hazard.

• If a foreign object or water gets inside MD4, turn it off immediately. Remove the AC power

cord from the AC outlet. Consult your dealer for repair. Using MD4 in this condition is a

ﬁre and electrical shock hazard.

• If you plan not to use MD4 for a long period of time (such as when you are on vacation),

remove the AC power cord from the AC outlet. Leaving MD4 connected is a ﬁre hazard.

• Do not use benzene, thinner, cleaning detergent, or a chemical cloth to clean MD4.
