E-10
— 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.
Refer to the respective user guides (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.
Note also that even when not being used, the battery pack will gradually discharge. If
this situation continues for a long period (several months or more), the battery pack
will become overdischarged, which may impair quality and performance.
— 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 terminal should be handled
so as to avoid impacts.
• Water or other moisture on the power-supply or data communication terminals
could cause sparking or an electric shock, and soiled contacts could block the
connection and impair charging functionality.
• While the DT-X400 is waterproofed, note the following when using this product:
• If the DT-X400 is exposed to water droplets, thoroughly wipe off the moisture with a dry
cloth.
• Do not use the DT-X400 for long periods in the rain.
• Securely close the battery pack cover and connector covers when using the DT-X400.
• Do not press hard on the screen (touch panel) or keys when using the DT-X400 in the
rain.
• The back of the DT-X400 may become warm during use. This is normal and does not
indicate a fault.
Weld Lines
There are seam-like markings in some locations on the terminal. These are
referred to as “weld lines” in the plastic forming process and are not cracks or scratches.
Weld lines do not interfere in any way with the operation of the terminal.
