zRefer all work related to the installation of this product to qualified service personnel or system installers.

zDo not operate the unit beyond their its specified temperature, humidity, or power source ratings.

Use the unit at temperatures between +5 ºC - +45 ºC {41 ºF - 113 ºF} and where the humidity is between 5 % - 90 %.

The input power source for NTSC model is 120 V AC 60 Hz, for PAL model is 220 V - 240 V AC 50 Hz.

Performance and lifetime of hard disk drives are easily affected by heat (used at high temperature) characteristically. It is recommended to use this unit at temperatures between +20 ºC - +30 ºC {68 ºF - 86 ºF}.

zPOWER switch

The POWER switch is located on the rear of the unit. Even though the POWER switch 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.

zBuilt-in backup battery

Before the first use, charge the built-in backup battery (lithium battery) by turning on the power for 48 hours or more.

If it is not charged enough, in a case where the power goes down, the internal clock may keep bad time or the operative condition may be different to that before the electric power failure.

The built-in battery life is approximately 5 years as an indication of replacement. (This is just an indication of replacement. 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.) Ask the dealer where you purchased the unit when replacement of the battery is required.

zHard 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 ºC {77 ºF}).

When hard disk drive trouble occurs, replace it immediately. Consult your dealer for servicing.

⋅Hard disk drives are precise devices. Do not leave them where the temperature is high and humid.

⋅Do not touch the connector of the removable hard disk by hand directly to protect the hard disk drive from static electricity.

⋅Take notice of the following for the removed hard disks.

⋅Do not leave them where the temperature is high and humid. It may cause condensation.

⋅Place them where the temperature is between 0 ºC {32 ºF} and 30 ºC {86 ºF} and humidity is between 20 - 40 % when they are not used for a long time (six months or more). Consult your dealer for further information.

⋅Operate them for around an hour at least once every six months when they are not used for a long time.

⋅When placing them stacked, do not stack more than four disks.

zHeat dissipation

Refer to the following to prevent fire and malfunction of the unit.

⋅Do not block the ventilation openings in the cover to prevent the unit from overheating. Maintain the unit periodically to prevent dust from blocking openings.

⋅Clear a space of more than 5 cm {1.97 "} from both sides, the top, and the rear of the unit.

⋅A lifetime of the cooling fan is limited by use.

zGrounding

Confirm that the wire is connected from the SIGNALGND terminal to earth ground.

A grounding connection must be made before connecting the power plug of the unit to the main power supply.

When disconnecting the grounding wire, make sure that the power plug of the unit is disconnected from the main power supply.

zAvoid placing the unit near noise sources

If the unit is placed near noise sources such as fluorescent lamps, noises may be produced. In this case, rewire avoiding the noise sources, or move the unit to the place far from them.

zPlaces to avoid

Do not place the unit in the following places:

⋅Places exposed to direct sunlight

⋅Places subject to having strong vibration or impact

⋅Near magnetic field sources such as a television or speakers

⋅Place where condensation forms easily, where temperature changes greatly, humid places

⋅Steamy and oily places such as kitchens

⋅Places which are not level

zCleaning

Turn the power off when cleaning the unit. Otherwise it may cause injuries.

Do not use strong or abrasive detergents when cleaning the unit body.

Use a dry cloth to clean the unit when it is dirty.

When the dirt is hard to remove, use a mild detergent and wipe gently.
