programs that were in operation and any data you may have saved to the device when you lost power. To avoid
this, make sure that you heed the low battery warnings and you supply AC power to the WebDT 375 before it loses
battery power completely.
You will receive warnings from the system when the device battery level is at critically low level. Within minutes
thereafter, the system will enter Forced Suspend mode. In this mode, the device can only be recovered with AC-
DC connected and Suspend button engaged. If the device is not revived within the next 2-4 hours, (depending on
device loading) the system will enter the Power Off mode due to battery depletion. To revive the system, you will
need to connect up the AC-DC and engage the Suspend button at the side of the device. During this process, you
may lose device settings or user data that have not been properly saved in the WebDT 375. To ensure that
settings such as profiles, dates, etc. are properly saved, you should engage the Save Registries function via Start >
Settings > Control Panel > Registries Save/Restore icon as soon after you made any modifications as possible. To
properly save user data, you should save the information or files to external flash memory such as My Computer >
Storage Card and its sub-folders.
What are some ways to extend battery life?
When you are not using the panel, give the Suspend button a quick press to put the unit into Suspend mode. With
the panel in Suspend mode, the battery life will be greatly extended. Also, when possible, do not use the highest
screen brightness setting. More battery power is used as the screen brightness increases. It is important to put the
unit into Suspend mode whenever you aren’t going to use it for more than a few seconds. It is possible to manage
the timed entry by the device into power saving modes. Go to Control Panel > Power > Schemes tab and choose
timings based on Battery Power or AC Power schemes.
Is there an advised practice for charging of the device battery packs?
The battery packs are constructed with Lithium-ion cells. There is no memory effect and you can charge these
batteries at your convenience without waiting for them to drain completely and without affecting the capacity of the
cells. However, it is still advisable to charge only when needed to conserve the number of charge/discharge cycles
for the battery packs since such cycles will affect the useful life of the batteries.
Can I charge or power the WebDT 375 from a vehicle power outlet?
Yes. There is an optional kit comprising a power cord and a DC-DC adapter to feed and charge the device from
vehicle power outlets.
NOTE:
Refer to the power adapter label specifications if the vehicle power outlet is not 12V.
I have acquired an optional external battery pack, what should I know and how should I make optimal use
of it?
The external battery pack has a capacity exceeds that of the internal battery pack. It adds about 3.5 hours of
usage time to the 2.5 hours of the internal battery. The custom housing readily snaps on and off the rear of the
WebDT 375. It is also designed to be
hot-swappable
with the system which means that one does not need to
power off the tablet prior to detaching or attaching the battery pack.
How can I charge the external battery pack?
The external battery pack can be charged as part of the WebDT 375 with the AC-DC adapter connected directly or
through the cradle. Alternatively, the external battery pack may be charged with an optional external battery
charging adapter and an AC-DC adapter.
NOTE:
When both are connected to the WebDT 375, the external and internal battery packs are charged
simultaneously.
