• Before you fi rst use this unit, supply power to it for at least 48 hours to charge the built-in backup battery so that the
built-in power compensator circuit can be activated. When the battery isn't charged suffi ciently, the built-in clock may
go wrong or the unit may not able to recover in case of a power failure.
• Don't plug this unit and high current devices (such as copier and air conditioning) into the same wall socket.
• Place this unit on a level and stable surface. When it is used on an unstable surface, a failure may be caused.
• Don't remove the outer covering of this unit.
• Don't place this unit close to other devices. They may interfere with each other, disturbing video and audio.
• Don't place this unit on a heat source. In addition, don't place this unit near a hear source because this unit has
ventilation openings in its sides and bottom. Otherwise the inside temperature may rise, causing a failure.
• When this unit is placed on or under the monitor, a failure may be caused, such as image disturbance.
• Don't place a strong magnetic object near this unit. It may affect the images adversely and cause loss of recorded
data.
• Don't expose this unit to volatile substances such as insecticide or don't leave this unit in contact with rubber or plastic
products for a long time. Otherwise the surface of the product may deteriorate or the coating may come off.
• When this unit is placed directly on the waxed fl oor, the adhesion may increase between the fl oor and the non-slip
rubber pads on the bottom of the product, causing the fl oor coating to come off or be colored.
• The HDD and cooling fans are motor-driven parts. To ensure stable recording, it is recommended to replace them
every 30,000 hours of use as a guide assuming that the ambient operating temperature is 25°C. When replacing HDD,
also replace the vibration-proof rubbers at the screwed areas. (Note that this period is just for a guide of replacement
interval and isn't intended to guarantee the lifetime of the parts. They may be broken earlier because of shocks applied
to the product and ambient operating temperature.)
• Be sure to use this unit within the allowable ambient temperature range (5° to 40°C) and humidity range (80% or less).
When you use the unit out of this temperature range, the internal parts may be adversely affected or a malfunction may
occur. In addition, when the temperature rises high, the characteristics of the HDD may deteriorate or its lifetime may
be shortened. When you use the unit in a low temperature environment, supply it with power for at least 10 minutes
before use.
• Clean the product regularly to prevent the ventilation openings from being covered by dust.
