Caution and care (continued)
• 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.
• Don't place this unit on a heat source. In addition, don't place this unit near a heat source because this unit has ventilation
openings in its side. Otherwise the inside temperature may rise, causing a failure.
• 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.
• When mounting this unit in a rack, ensure that the temperature inside the rack doesn't rise to 40°C or higher. When
installing a rack, you are recommended to install fans to keep the temperature inside the rack 30°C or lower.
• Don't install a device that becomes hot under this unit. Otherwise the inside temperature may rise, causing a failure.
• Don't give a shock to all HDD devices in the rack.
• Before taking this unit in or out of the rack, be sure to turn off HDD devices being energized in the rack.
• Don't place this unit near a device that generates vibrations.
• When moving this unit, be sure to turn off the MAIN switch, make sure that the unit is completely stopped, and then unplug
the power cord. When this unit is exposed to excessive shock while being energized, the internal electronic parts or HDD
may be damaged. Be careful especially while the power indicator or access indicator is blinking.
• Don't move this unit for at least one minute after you turn off the power. Even after the power is turned off, the disc in the
HDD keeps rotating by inertia for a while and the head is in an unstable state. This unit in such state is more vulnerable to
vibrations and shocks than while being energized. Be careful not to give this unit even a slight shock for at least one minute
after turning off the power. Wait at least one minute for the disc to stop, and then you can move the product.
• When moving this unit, cover it with shock absorbers to prevent shocks to the inside.
• When placing this unit on a fl oor, lay it gently on a soft mat or cloth.
