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.

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.
•  Do not move the system while the power is on.
•  Do not use the system in excessively hot or humid places, or in 

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.

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.
