Using the Internal Battery
Every time that you connect the AC adaptor to the unit, the internal battery recharges. This
way, you can use the unit without the need of always connecting it to the AC adaptor. This
section contains information about the unit’s internal battery.
Internal Battery
To maintain a stable power input, the unit is equipped with an internal battery. When you
use the unit for the first time or when the internal battery charge is low, it is necessary to
recharge the internal battery. When the internal battery is recharged, you do not need to
connect the unit to the power outlet to use it.
The battery indicators show the status of the internal battery.
• When using the unit at low temperatures (50˚F (10˚C) or less),
connect it to the AC adaptor as the battery life tends to shorten.
• Do not let the battery run out when reading or writing data, as this
may damage data and/or the hard disk.
• If the unit is not connected to the power outlet and it fails to start
even though the internal battery is not depleted, recharge the
internal battery or use the AC adaptor. Depending on the
operating conditions, starting the unit may demand more energy
than usual from the internal battery.
Status Indicator Meaning
During operation • Indicates the remaining charge as shown below when Giga Vault is used only
with the battery:
3 Lit Green: Full charge
2 Lit Green: Charge low (approx. 10 to 60% remains)
If you connect the unit to your computer when the internal
battery is at this level, it may not have enough remaining charge
to power the unit. If this is the case, connect the AC adaptor.
Blinking Red: Charge extremely low (less than 10%)
• When the AC adaptor is connected and used as the power source, the three
green indicators light only when the battery is fully charged.
Recharging The status of the battery charge is indicated as:
3 Lit Orange: Full charge
2 Lit Orange: Charge low (approx. 10 to 60%)
1 Lit Orange: Charge extremely low (less than 10%)
You can recharge the internal battery either when it is connected to or disconnected from
the Portable HardDisk Media.
