NOTE

The internal switching relays are rated for 0.3 A at 125 V AC or 1 A at 30 V DC. If the electric current is higher than that the unit can be damaged.

HDD INSTALLATION

Note for Hard Disk Drive

 

The internal hard disk drive (HDD) is a fragile piece of equipment.

 

Please follow the guidelines below when using the system to

 

protect against possible HDD failure. We recommend that you back

 

up your important recordings onto an external backup device in

 

order to prevent accidental loss.

 

Make sure that the power is turned OFF when attaching or

 

removing the HDD.

3

Do not move the system while the power is on.

 

Do not use the system in excessively hot or humid places, or in

Installation

 

places that may be subject to sudden changes in temperature.

 

 

 

Sudden changes in temperature can cause condensation to

 

 

form inside the system. This can be a cause of HDD failure.

 

While the system is switched on, do not unplug from the wall

 

 

socket or switch the electricity off from the breaker switch.

 

If there’s a power failure while the system is on, some data on

 

 

the HDD may be lost.

 

Do not drop the HDD. Also do not put the metallic object such

 

 

as coins or screwdrivers into the HDD tray.

 

When a power failure occurs during recording, avoid adding,

 

 

replacing or transporting the HDD as the recorded data may be

 

 

erased. In this case, turn the power back on to boot up the unit

 

 

normally with the HDD that was being used at the time of the

 

 

power failure attached. Then add, replace, or transport the HDD.

 

The HDD is very delicate. Handle the HDD with care and follow

 

 

the precautions below because even a tiny shock may damage

 

 

the internal components of the HDD.

 

 

-- Do not place the HDD on the desk or table directly. Put a

 

 

 

thick cushion under the HDD because even a small shock

 

 

 

may damage the internal components of the HDD.

 

 

-- Do not use an electric screwdriver. Vibrations and shocks

 

 

 

caused by an electric screwdriver may damage the internal

 

 

 

components of the HDD.

 

 

-- When replacing the HDD, do not knock the HDD with other

 

 

 

components such as another HDD and the HDD tray.

 

 

-- Do not knock the HDD with tools such as a driver when

 

 

 

replacing the HDD.

 

 

-- Protect the hard disk drives from static electricity.

 

Installing the Hard Disk Drive

 

You can install up to 1 HDD.

 

Improper installation or setup may disturb HDD recognition or

 

normal product operation. So you should consult with an expert

 

from the store where the product was purchased.
