2. HANDLING PRECAUTIONS
• The supplied power supply cord is designed for exclusive use with the Digital Video Recorder. Never use it
with other equipment.
• Do not connect the10BASE-T/100BASE-TX terminal, Hard disk expansion unit connection terminal or
Remote control I/O terminal A to networks that could be exposed to excessive electrical voltage. Failure to
follow this instruction could result in electric shock or fire.
• It is recommended that the Recorder be always used in locations where the ambient temperature ranges
from +5°C to +40°C (41°F to 104°F) and humidity levels of less than 80% to ensure that no condensation is
formed.
• When moving the Recorder, first disconnect its power supply plug from the AC outlet 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. Also, 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.
• 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 power and disconnecting the power
supply plug from the AC outlet. It is highly recommended that the ventilation slots be cleaned once a year.
• When cleaning the Recorder, be sure to switch off the power. Wipe with a soft dry cloth. If it gets very dirty,
use the soft cloth slightly moistened in neutral cleanser. Never use volatile spirits like thinner, benzine, or
alcohol. Such chemicals may damage its plastic 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 (3.9 inch) away from the nearest
wall surface.
• Since the Recorder is equipped with a cooling fan, a motor sound is generated. Avoid installing the Digital
Video Recorder in locations which resonate electrical motor noise.
• 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.
• The Recorder can be used only in a commercial and industrial area. Operation of this equipment in a
residential area is likely to cause radio disturbance and TV interference.
• 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.
• Avoid using the Recorder in locations exposed to vibration. The Recorder is a piece of precision equipment,
as this may cause the unit malfunction.
• 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
• If the hard disk fails, recorded data cannot be restored.
• Save important recordings to DVD-R/RW disks.
• Recordings copied from video images or video recordings with registered copyrights may not be used for
commercial purposes other than for private use without express permission from the copyright holder.
