4. HANDLING PRECAUTIONS
• Use the Digital Video Recorder in locations with ambient temperature of between +5°C and +40°C, and
humidity levels of less than 80% to ensure that no condensation is formed.
• When moving the Recorder, first switch off the main power and then wait at least 30 seconds before moving.
• Avoid moving the Recorder suddenly from a cold location to a warm location, or installing it in close proximity
to an air-conditioner outlet, as internal condensation could result. When condensation occurs, do not switch
on the power until the Recorder has sufficiently dried.
• Avoid installing the Recorder in humid or dusty locations, or in locations exposed to direct sunlight, sooty
smoke or steam. Note that even in locations which are not particularly dusty, dust may accumulate at the
Recorder’s ventilation slots. Because this could cause an extreme rise in temperature inside the Recorder,
be sure to clean the ventilation slots periodically after switching off the main power and disconnecting the
power supply cord from the AC outlet. It is highly recommended that the ventilation slots be cleaned once a
year.
• The socket-outlet shall be installed near the equipment and the plug (disconnecting device) shall be easily
accessible.
• To clean, be sure to first switch off the main power and then wipe with a dry cloth. If the Recorder is
particularly dirty, use a cloth damped in a neutral detergent. Never use benzene, thinner or chemically-
impregnated towels, which may damage the Recorder’s surface.
• Do not block the ventilation slots or cooling fan, which could cause the temperature inside the Recorder to
rise, possibly resulting in unit failure. Install the Recorder at least 100 mm away from the nearest wall
surface.
• Since the Recorder is equipped with a cooling fan, a motor sound is generated.
• Do not install the Recorder in locations influenced by strong electrical or magnetic fields, as monitor screen
pictures may become distorted or the Recorder could fail.
• Avoid jarring or striking the Recorder. The Recorder is a piece of precision equipment and accidentally
dropping it or subjecting it to strong impacts could cause its failure. When transporting the Recorder,
carefully pack it in the supplied carton to protect it from shock.
• Do not use the Recorder in locations exposed to vibration to avoid failure. Avoid installing the Recorder
vertically or tilting it at extreme angles, since it is designed to be used in a horizontal position only.
• About the hard disks
Hard disks other than those specified by TOA cannot be used. Since the hard disks are pieces of precision
equipment, take special care in handling not to accidentally drop, bump or jar them, lest they should fail.
If a hard disk on which condensation is formed is used, it could fail. Therefore, when brought into a warm
room from the cold outdoors, be sure to leave it unused for at least half a day before using it. If the hard disk
fails, recorded data cannot be restored.
• TOA takes no responsibility for any incidental damage, such as loss of sales opportunities, that may result
from the Digital Video Recorder’s failure.
• The standby function is used to enable transportation of the unit from one place to another when
circumstances do not permit its main power supply to be turned off. While in standby mode, power continues
to be supplied to the unit, but its hard disk and fan are stopped. If the unit is left in standby mode for long
periods of time, heat can build-up inside the unit, potentially shortening its operating life. To avoid this, be
sure to turn off the main power supply when the unit is not in use.
