Thank you for purchasing this Nexto Video Storage product.

Nexto Video Storage allows videographers to save footage from camcorders to a
hard drive, without using a computer. The camcorder can then be used to record
new data. NextoDI has optimized the performance of the Nexto Video Storage so
that data transfers from camcorders to Nexto Video Storage more quickly than to
other storage devices. Data stored on the Nexto Video Storage can later be copied
to a computer. Nexto Video Storage can also be used as a computer backup device.

Nexto Video Storage supports professional video cameras from many manufacturers,
including Sony and Panasonic (which use high speed PCI Express/PCMCIA flash
memory cards for HD video), and memory formats such as Compact Flash(CF), Secure
Digital(SD), SDHC, Multi Memory Card(MMC), Memory Stick(MS), and xD Picture Card.

Please read this manual before using the product. Follow operating instructions
carefully to avoid damage to the product, or personal injury. This guide assumes
that your Nexto Video Storage unit contains a properly formatted hard drive and
a charged battery. If this is not the case, refer to the later chapters on inserting
a hard drive and charging the battery.

1. Product Description

2. Contents of the Nexto Video Storage Package

The Nexto Video Storage product allows videographers to save footage from
camcorders to a hard drive, without using a computer. The camcorder can then
be used to record new data. NextoDI has optimized the performance of the
Nexto Video Storage so that data transfers from camcorders to Nexto Video
Storage more quickly than to other storage devices.

The Nexto Video Storage device uses a 2.5" Serial ATA (SATA) hard drive. Data
stored on the Nexto Video Storage can later be copied to a computer – any
computer that recognizes USB or eSATA drives, including PCs and Macintoshes.
Nexto Video Storage can also be used as a computer backup device. The main
task of the product is to copy data from camcorders or other devices onto the
hard drive without using a computer.

A Compact Flash slot, a 4in1 memory slot for SD/SDHC/MMC/MS/xD and a USB
mini-AB type connector are available. A USB flash drive or a card reader can be
connected to mini USB port with the USB host adapter cable.

When copying data from camcorders, memory cards, or USB devices to the Nexto
Video Storage, transfers are faster than with comparable products, because of
NextoDI’s proprietary xCopy technology.

Power is supplied via a built-in LiPo rechargeable battery or via an AC power
adapter unit which is also responsible for charging the batteries.

Functions are controlled via a built-in LCD display with easy one-key operation.
The features include:

● Built-in LiPo rechargeable battery for extended running time and easy

charging.

● Ability to copy data (via Compact Flash slot, 4in1 slot or USB type mini-AB

connector) to the hard drive, without using a computer.

● Quick data transfer from memory cards to the hard drive.

● Hardware based full bit-bit data verification for error free data copy.

● Two ways to connect to a computer - via USB2.0 and high speed eSATA.

Read these operating instructions carefully. They contain important
information on installation, operation and handling of the Nexto Video
Storage.

① Hard drive enclosure with built-in LiPo rechargeable battery
② AC power adapter(wall plug charger)
③ USB cable for computer connection
④ eSATA cable for computer connection
⑤ USB host adapter cable for USB device connection.

A "LiPo" rechargeable battery is included in the Nexto Video Storage (lithium-polymer). This
rechargeable battery does not have the so-called "memory effect", i.e., the rechargeable
battery can be charged whenever you want. Furthermore, it is more powerful than
conventional NiCad and NiMH rechargeable batteries. Note these important instructions
when handling the LiPo rechargeable battery

● Never damage the rechargeable battery. Damaging the wrapping of the

rechargeable battery might cause explosion or fire. If battery fails, see the
chapter on "Disposal".

● Never short circuit the contacts of the rechargeable battery. Never touch
connections or electric components inside the Nexto Video Storage with
metal objects.

● Charge the rechargeable battery regularly, even if you do not use the
product. The Nexto Video Storage needs "current" (a small quantity) at all
times. Due to the rechargeable battery technology, it is not necessary to
discharge the battery before recharging. Recharge the battery completely,
about once a month. The device will be ready for use at all times.

The battery can be charged using the AC power adapter unit delivered with this product.

1. Connect the charger’s wall plug to the Nexto Video Storage’s "DC IN" connection.

2. Plug the AC power adapter unit into a wall socket.

3. The LED on the Control (Copy) key shows red during the charging.

4. When the battery is charged, the red LED turns off.

5. If there is an error when charging, the LED blinks. If this happens unplug the AC adapter
unit and plug in it again.

6. If the optional external battery is connected to the "BAT" connector, both internal and
external battery charged at the same time.

7. With a completely empty rechargeable battery, the charging procedure lasts
approximately 5 hours.

● Charging via USB (without the AC power adapter unit) is possible. A high

power USB connection is needed, i.e. a USB connection with its own power
supply (such as the USB port of a computer or a USB hub with power unit).
Charging via USB takes place only when the Nexto Video Storage is turned
off.

● If the Nexto Video Storage is operated with a notebook, then you must

always use the AC power adapter unit to charge the Nexto Video Storage,
as notebooks cannot deliver the necessary current via USB.

13. Installing and Formatting a Hard Drive

The Nexto Video Storage is sometimes delivered with a hard drive installed. If a drive is not
included, or if the drive fails, or if you wish to install another hard drive, you may do so. You
need a 2.5" Serial ATA hard drive; its installation height must not exceed 9.5mm. Supported
hard drive capacity is up to 2,000GB.

Nexto Video Storage does not support PATA or IDE hard drives.

Disconnect all cables from the case.

●Remove the cover on the lower side.

●Insert a 2.5" SATA hard drive.

The protective film must be placed between
circuit board and hard drive.

●Make sure that the pins of the hard drive are

inserted exactly in the socket board inside
the case.

●Put the cover on again. Make sure to observe the

correct orientation; the larger foam insert on the
inside of the cover faces in the direction of the
power socket/USB port.

● Fasten the cover via the four small screws;

a suitable screwdriver is included.



The hard drive must then be formatted.

Formatting the Hard Drive

The hard drive in the Nexto Video Storage must be formatted as file system "FAT32". Only
one (or the first) partition can be used. With Windows XP, hard drives and partitions are
formatted (with a size of more than 32GB) only with the file system "NTFS"; no “FAT32”
format option is available. For Mac OS, hard drives are formatted with the file system HFS+
(Mac OS Extended).

If you are installing a 60Gbyte hard drive and creating and formatting a partition
via the operating system "Windows XP”, the file system "NTFS" will be installed.
Via USB2.0, the hard drive in the Nexto Video Storage can be used like a
conventional external hard drive. If the Nexto Video Storage is disconnected
from the computer and you want to copy the data from a memory card onto the
hard drive, then this is not possible. The Nexto Video Storage can work with one
partition in the file format "FAT32" only. Therefore, Nexto Video Storage offers
its own possibility of formatting the hard drive in the file system "FAT32".

To Format a New Hard Drive

The Nexto Video Storage must not be connected to the computer via USB or eSATA. Remove
any memory cards or USB devices from the Nexto Video Storage.

● When the Nexto Video Storage is turned on after installing a new hard drive, an error
message appears ("Disk Format Error"), indicating that the drive is not formatted (new hard
drives are usually delivered non-partitioned and non-formatted).

● Press the control key for more than one second ("L format"); Nexto Video Storage will format
the new hard drive; the available space on the hard drive is formatted as one partition in the
FAT32 Format.

● Confirm the selection by pressing and holding the control key

for longer than 1 second.

Using a Hard Drive which is Already Formatted

If you have a spare 2.5" hard drive you may use it in the Nexto Video Storage. If the

partition (or the first partition, if several are created) is a FAT32-partition, then it can be

used directly. The existing data will not be overwritten or deleted. Further partitions (e.g.

the second or third partition existing on the hard drive) cannot be used; they are available

● Afterwards, you can repartition and reformat the hard drive;

to confirm press the control key for longer than 1 second (to
cancel, briefly press the control key ).

●All data on the hard drive will be lost!

to your computer when the Nexto Video Storage is connected to the computer via USB or

eSATA. Also, you can use the old hard drive by, partitioning/reformatting it. However all
data on the hard drive will be lost. Connect the Nexto Video Storage via USB to the
computer and back up the drive first if necessary.

All existing partitions will be deleted. One single new partition of the whole
existing memory of the hard drive will be created in the file system "FAT32".

Be sure to backup data on the hard disk before using it in the Nexto Video
Storage.
