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}.

The
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.
