• If the battery pack is removed from the Smart Device without first shutting down or
switching to Hot Swap mode, the time may be reset.
• Lithium-ion Battery Pack
Each lithium-ion battery pack has its life. The life span heavily depends on how the battery
pack is charged or stored which may cause deterioration of the battery pack to shorten the
life span if it is handled improperly. Note the tips below to make the battery pack last long.
— Be sure to charge the battery pack before using it if the battery pack is used for the first
time or if it has not been used for a long period of time. When charging the battery
pack, continue charging until the charge LED lights green (fully charged).
— If the battery pack is repeatedly charged, the life span becomes short. To avoid the
repetition of charging the battery pack, be sure that the remaining capacity is low
before you start charging.
— Be sure to charge the battery pack in recommended temperature range. The temperature
range is dependant on device you use to charge including battery chargers and tablets.
(download version). Charging the battery pack in a temperature outside of the
recommended range causes deterioration.
— When used at low temperatures, the battery pack has a reduced capacity and will
supply power for shorter time. The life span of the battery pack is also shortened.
— Charging the battery pack while the battery pack itself is freeze including inside causes
deterioration. Be sure to resume an ordinary room temperature on the battery pack and
then leave it unattended for approximately one hour before charging.
— After charging the battery pack, if the performance of the battery pack does not show
any recovery, it is a sign of ending the life. Replace it with a new battery pack.
— Avoid the battery pack with a full of the capacity to store for a long period of time. If
you need to store it for a long period, be sure that the remaining capacity is 30 to 50
percent and to store in a moderate low temperature. This can reduce deterioration.
— The battery pack gradually deteriorates over time. In particular, storing (or using) the fully
charged battery pack at high temperatures tends to accelerate battery pack deterioration.
• Drop resistance
The drop resistance is a test value only and is not guaranteed.
Repeated or frequent shocks may still result in damage, so the Smart Device should be
handled so as to avoid impacts.

Installing and Replacing the Battery Pack
Your Smart Device uses two types of battery: a battery pack and a memory backup battery.
The battery pack is used to power normal operations and to store data, while the memory
backup battery provides the power required to maintain memory contents when the battery
pack power is unable to supply power for some reason.
You can choose either battery pack (HA-R20BAT) or large-capacity battery pack
(HA-R21LBAT) for operating power.
The backup battery is installed inside of the Smart Device.

This guide uses the following terms to refer to the batteries.
Battery Pack:

Rechargeable battery pack (HA-R20BAT or HA-R21LBAT) for normal
operations and data storage

Backup Battery: Built-in battery for memory backup
When the battery pack power goes low, immediately charge it or replace it with a charged
battery pack.
You can charge the battery pack using the AC adapter, four-bay battery charger, four-cradle
battery charger, USB cradle, or LAN cradle. See the relevant sections in this guide for the
respective options about how to use.

E-14

Important!
Always keep backup of all important data!
• The battery pack powers normal operation and also provides power required to
maintain memory contents, while the backup battery provides backup power to
maintain memory contents. Because of this, you should not remove the battery pack
if the backup battery is dead. Removing the battery pack while the backup battery is
dead causes data in the memory to be corrupted or lost. Note that once data is lost it
cannot be recovered. Always keep backup of all important data.
• The charge of a battery pack when you purchase it may be depleted due to testing at
the factory or natural discharge during shipment and storage. Be sure to charge the
battery pack before you use it.
• The life of a battery pack is limited, and charging a battery pack causes it to
gradually lose its ability to maintain the charge. If your battery pack seems to
require charging very frequently, it probably means it is time to purchase a new one.
• If a battery pack is used past the end of its service life, it may swell up in size. In such
a case, replace the battery pack with a new one.
• It takes approximately 4 hours with the main battery pack installed in the terminal
for the backup battery to be charged fully.
• If a battery pack is installed in the Smart Device, it will still work when the battery
cover is open. However, the battery cover should be closed when using the Smart
Device in case the battery pack unexpectedly drops out and causes data loss.

Installation
1. Turn the Smart Device over.

Handling the NFC
The NFC is a technology of contactless IC card for short range communication that enables
writing data to card and reading data from the card by applying the card close to the NFC
Reader on IT-G400.
The integrated NFC can read a contactless IC card used typically for employment
identification, etc.
1. Hold the card flat against the NFC reader on the back of the Smart Device (near the
center of the battery cover).

Important!
• If there are problems reading the card, check that the battery cover is completely
closed and try sliding the card back and forth or left and right.
• Do not apply card while it is overridden by other card. The NFC may not read it
correctly.
• A metal object near by the NFC Reader may cause the NFC not to read card
correctly. Take the card out of a wallet if the wallet is with metal object before
applying it to the NFC Reader.
• Apply card in parallel with the NFC Reader to touch the NFC Reader with the card.
• The NFC reader function in the Smart Device uses very weak radio waves that do
not require a radio station license.
• Frequency band used by the NFC is 13.56 MHz. Secure a sufficient space between
IT-G400 and other reader/writer located in the vicinity. Make sure also that a radio
station employs the same frequency band does not locate near by prior to using
IT-G400.

E-26

Performing Communications
Bluetooth® Communication

Bluetooth® interface can also be used to transfer data between two Smart Devices.
With Bluetooth® the two Smart Devices should be located within about five meters from
each other, as long as there is nothing blocking the path between them.

Important!
Observe the following precautions to help ensure that Bluetooth communication is
successful.
• Make sure two Smart Devices face each other within five meters. Surroundings
(obstacles) between the Smart Devices may cause a shorter distance.
• Make sure there is at least two meters between the Smart Device and other
equipment (electrical appliances, audio-visual equipment, OA equipment, and
digital cordless telephones, facsimile machines, etc.). Take special care with
microwave ovens. Allow at least three meters between the Smart Devices in
wireless operation and a microwave oven. When operating the terminal in
Bluetooth nearby these devices and electrical appliances with their powers being
turned on, communication may be interrupted or radio receptions may be
interfered.
• Normal communication may not be possible in an area near a broadcast
trans-mitter or wireless transmitter. If this happens, move the Smart Device to a
different location. Normal communication may not be possible in areas exposed to
strong radio waves.
• Interference by WLAN
Because Bluetooth® and WLAN use the same frequency band (2.4GHz), radio
interference can occur if there is a WLAN device nearby. This can result in lower
communication speed, or even make it impossible to establish a connection. If this
happens, try the following countermeasures.
• Move at least 10 meters away from the WLAN device.
• If you cannot keep the distance at least 10 meters or more between the Smart Device
and a WLAN device, turn off the power of either the Smart Device or the WLAN
device.
• If the Smart Device’s wireless LAN and Bluetooth® communication are used at the
same time, ambient radio signals may make communication impossible.

E-27

WAN Communication
A contract with a communications provider is required in order to use the WAN communications
functions built into the Smart Device. The available WAN communications functions will be
determined by the contract between the customer and his or her communications provider.
Consult your communications provider for details of the network services.

GPS
When you use the Smart Device for the first time or after an extended period of no use, it
may take a long time before the Smart Device determines its positioning. In such a case,
operate the GPS mode where there are no obstacles in the surroundings and wait for at least
15 minutes or longer.
The GPS module integrated in the Smart Device uses signals emitted by the satellites
operated by the government of the United Sates. The accuracy of positioning information
you obtain on the Smart Device may be affected by the condition of these satellites.
The GPS module may not be able to receive the signals in locations such as inside a building
or in a tunnel. If you are installing the device in your car, determine the installation location
after making sure that it can receive the signals.

Using Rechargeable Battery Packs
HA-R21LBAT

HA-R20BAT

You can choose between two battery packs with different capacities for the Smart Device,
depending on how long it will be used and the operating environment.

Important!
• Store a battery pack in its special soft case whenever you are not using it.
• If the battery pack has been left over unused for a long period of time, the capacity
remained decreases due to spontaneous discharge or chemical decomposition by the
battery pack itself. If the battery pack fails to hold its operating duration after it has
been fully charged, replace it with a new one. The battery pack may reach the end of
its service life.
