Ambient operating temperature
Use this product at temperatures between +5 °C to +45 °C 
{+41 °F to +113 °F}. Failure to do so may damage the inter-
nal parts or cause malfunction. Performance and lifetime of 
hard disk drives are easily affected by heat (used at high 
temperature). It is recommended to use this product at tem-
peratures between +20 °C to +30 °C {+68 °F to +86 °F}.

The POWER switch is located on the rear of this product. 
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 this product from the AC outlet. When using 
the power supply control unit, turn off the power of the 
power supply control unit. 

Built-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 approx. 5 years as an indication

of replacement. (The built-in battery life may become 
shorter depending on the use condition.)Replace the 
built-in battery after 5 years of use. ("5 years of use" is 
just an indication of replacement. We are not providing 
any guarantee of the built-in battery lifetime.)When the 
built-in battery life runs out, some settings such as the 
time and date setting will not be saved once the power 
is turned off.

 •  Ask your dealer when replacement of the battery is

required.

     

Hard disk drive (HDD)
 •  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 the power off (for

around 30 seconds).

 •  The lifetime of hard disk drives is limited by use. Write

errors may occur frequently after around 20 000 hours of 
operation, and the head and motor deterioration may 
occur after around 30 000 hours of operation. They will 
reach the end of their lifetime after 30 000 hours of oper-
ation if they have been used at the recommended ambi-
ent temperature (approx. +25 °C {+77 °F})

 •  It is recommended to replace them after around  

18 000 hours of operation to prevent data loss from disk 
failures.

 •  When hard disk drive trouble occurs, replace it immedi-

ately.

    Contact your dealer about servicing.
