• 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 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

Protect the hard disk drives from static electricity.
Do not stack them, or keep them upright.
Do not use an electric screwdriver to fix them.

Avoid rapid changes of the temperature/humidity to
prevent condensation. (Acceptable change: within
15 °C/h (59 °F/h))
• Place the unit horizontally an a level surface. Do not
place the unit in an upright position. When stacking
multiple units, clear a space of more than 5 cm from
both sides, the top, the bottom and the rear of the units.
