2.1 Handling and Operating Precautions


Be sure not to continue to use IT-G400 with main battery low status. Operation data might
be deleted or changed. Please replace battery immediately when it gets main battery low
warning.

Observe environmental specification range. It might cause failure if IT-G400 is used out of
environmental specification range.

Be sure to use IT-G400 in below environment. It could cause failure.
 Environment prone to static electricity
 Environment of extreamly high and low temperature
 Environment of high humitidy
 Environment prone to extream temperature change
 Environment of dusty

About stylus (pen), be sure to use dedicated stylus (pen) of IT-G400. If another stylus (pen)
is used, it might cause failure.

Lithium-ion Battery Pack
 Each lithium-ion battery pack has its life. Life span depends on how battery pack is
charged or stored. It might cause deterioration of battery pack and shorten life span if
it is handled improperly. If battery pack performance does not show any recovery after
charging, it is sign of ending the life. Replace with new battery pack.
 Battery pack should be fully charged before first time use or after a long period since
last time use. When charging battery pack, continue to charge until charge atatus LED
turns green (fully charged).
 If battery pack is often charged repeatedly, life span becomes shorter. To avoid
charging repeatedly, it is recommended to start to charge when it gets battery level
low.
 Be sure to charge the battery pack in environmental specification range. Charging in
out of environmental specification range can cause deterioration.
 When used at low temperatures, battery level reduces quickly, so operation time gets
shorter. Moreover, life span of battery pack gets shorter. After operation in low
temperature, return battery pack to room temperature about 1 hour, then start to
charge it if it needs.
 Do not store battery pack with full charge state if it needs to be stored for long period.
It needs to be 30 to 50% for a long period storage in moderate temperature. It can
reduce deterioration.
 The battery pack gradually deteriorates as time goes by. Especially, storage (or
operation) of battery pack with fully charged at high temperatures tends to accelerate
battery pack deterioration.

IT-G400 uses the high sensitive communication modules inside, for the better data
communication, avoid using the equipment to generate radio wave (mobile phone, etc)
near IT-G400. Please keep it away (more than 30 cm in case of the mobile phone).
