being damaged.

3 Do not use damaged disks. Product can be damaged.

Do not dismantle or change the structure of the system in any way.

This may cause electric shock.

When dealing with system components, strictly abide by the instruction manual.

Physical contact with the soldering on the backside of components may cause severe injury.

When transporting the system, rst turn o the system and disconnect the unit

from the power source. Sudden tension in cables can cause severe damage to the system. Loose cables can cause injury.

Take caution when handling the system so as not to corrupt the hard disk data.

- Take caution not to bump or expose the system to extreme temperatures, as it may damage the sensitive hard disk.

- Take caution when turning on the electricity, as during this time any external bumps to the system may corrupt the hard disk data.

- The manufacturer disclaims all responsibility for loss of hard disk data.

Safety warning

Related to damage to the HDD and data:

- during installation or disconnection of the system, ensure that the system does not experience any external physical shocks.

- During the operation of the HDD, short surges and stoppages of power may cause the system to turn o and on quickly.

- there may be a sudden stoppage of electricity during operation

- avoid moving the system during operation of the HDD, which may cause external physical shock

- during the conguration of new volumes.

i) if during use, existing volumes are deleted and new volumes are created, data

will be lost.

ii) Before conguration of new volumes, each user must back up data, as well as

when creating new volumes, to ensure the possibility of restoration.

– e.g. virus infections.

• Always back up hard disk data to avoid accidental data loss.

In the event of the administrator forgetting the password, restoration is impossible. Hence safeguard the password.

• To create a new password, the system must be re-initialized. In this case, all data will be lost, and data recovery will be impossible, for security reasons. The manufacturer disclaims all responsibility in the event of this occurrence.

In the event of the cover being removed during operation, the user risks electric

shock, injury, and damage to the system.

electric shock.

Safety warning

In the event of lighting and thunderstorms, immediately physically disconnect the

system from any power source, to avoid damage to the system.

In the event of dropping the system, contact the service centre for advice and

possible service. Not doing this creates the risk of damage, re and electric shock.

Keep the system away from direct sunlight to avoid overheating, and melting of

the case, which may eventuate in re and injury.

Do not place ammable objects, candles or cigarettes on the system, as this may

cause re

In the event of a burning smell or smoke emanating from the system, immediately

disconnect the power, and contact the service centre.

Keep heating devices and other electrical components at a distance from the

system to avoid case melting, and hence the danger of damage, re, and electric shock.

Before disassembling the system, always ensure physical disconnection of the

electrical cable from the socket.

21 Do not disassemble the power supply, to avoid the danger of electric shock.

Keep children away from the system, as consuming any parts will cause serious injury.

In the event of swallowing any parts, such as screws, immediately seek medical treatment.

Ensure that multipoint power sockets are not overloaded, to avoid the danger of re and electric shock. Ensure that cords are always neatly arranged and are

not trapped under the system or other heavy objects. When connecting and disconnecting the electrical cord, take care in handling the socket to avoid the danger of electric shock.
