Precautions
Refer all work related to the installation of this product
to qualified service personnel or system installers.
When the model in use is the NTSC model, connect the
unit to a 120 V AC power source.
When the model in use is the PAL model, connect the
unit to a 220 - 240 V AC power source.
Do not connect this unit to an outlet to which appliances
with high power consumption such as an air conditioning or
a copy machine is already being connected.
Do not operate the unit beyond its specified tempera-
ture, humidity, or power source ratings.
Use the unit at temperatures between 5 °C - 45°C {41 °F -
113 °F} and where the humidity is between 5 % - 90 %.
Performance and lifetime of hard disk drives are easily
affected by heat (used at high temperature) characteristi-
cally. It is recommended to use this unit at temperatures
between 20 °C - 30°C {68 °F - 86°F}.
POWER button
The POWER button is located on the rear of the unit. Even
though the POWER button is set to "OFF", the power supply
will not be cut. To cut the
power supply, unplug the
power plug of the unit from
the AC outlet. When using
the power supply control
unit, turn off the power of
the power supply control
unit.
Built-in backup battery
The built-in battery life is approximately 5 years as an indi-
cation of replacement. (This is just an indication of replace-
ment. We are not providing any guarantee of the built-in
battery lifetime. Replacement cost of the built-in battery is
not covered by the warranty even if it needs to be done
within the warranty period.) When reaching the end of its
lifetime, the time and date setting will not be saved after the
power of the unit is turned off. Ask the shop where you pur-
chased the unit when replacement of the battery is
required.
Built-in hard disk drives
Hard disk drives are vulnerable to vibration. Handle them
with care.
It is possible to damage them if they are moved while their
motors are still running. Do not move them just after turning
their power on or off (for around 30 seconds).
A lifetime of hard disk drives is limited by use.
It is recommended to replace them after around 18 000
hours of operation to prevent data loss from disk failures.
Write error may occur frequently after around 20 000 hours
of operation and the head and motor deterioration may
occur and will reach their lifetime after 30 000 hours of
operation when they have been used at the recommended
ambient temperature (approx. 25 °C {77°F}).
When hard disk drive trouble occurs, replace it immediate-
ly. Consult your dealer for servicing.
When replacing the hard disk drives, take notice of the fol-
lowing.
• Protect the hard disk drives from static electricity.
• Do not stack them, or keep them upright.
• Do not use an electric screwdriver to fix them.
(Tightening torque: Approx. 0.49 N·m {5 kgf·cm})
• Avoid rapid changes of the temperature/humidity to
prevent condensation.
(Acceptable change: within 15 °C/h {59°F/h})
Avoid the following locations for installation.
• Places exposed to direct water, moisture, or sunlight
directly
• Places subject to having strong vibration or impact
• Near magnetic field sources such as a television or
speakers, magnet, etc.
• Steamy and oily places such as kitchens
• Places which are not level
• Place where condensation forms easily, where temper-
ature changes greatly
Place the recorder horizontally on a level surface.
Do not place the recorder in an upright position. When
stacking multiple recorders, clear a space of more than 5
cm from both sides, the top, the bottom and the rear of the
recorders.
Heat dissipation
Refer to the following to prevent fire and malfunction of the
recorder.
• Do not block the ventilation openings in the cover to
prevent the recorder from overheating. Maintain the
recorder periodically to prevent dust from blocking
openings.
• A lifetime of the cooling fan is limited by use. Contact
your dealer for servicing.
Avoid placing the recorder near noise sources
If the recorder is placed near noise sources such as fluo-
rescent lamps, noises may be produced. In this case,
rewire avoiding the noise sources, or move the recorder to
the place far from them.
Grounding
Confirm that the wire is connected from the SIGNAL GND
terminal to earth ground.
A grounding connection must be made before connecting
the power plug of the recorder to the main power supply.
When disconnecting the grounding wire, make sure that the
power plug of the recorder is disconnected from the main
power supply.
