Important! • Removing the lithium ion battery pack from the Data Collector
consumes backup lithium battery power, which is used to retain data
in memory. This is no problem for short periods, but leaving the Data
Collector without a charged lithium ion battery pack for long periods
can cause the backup battery to go dead, resulting in loss of all
programs and data stored in Data Collector memory. Because of this,
we recommend that you keep charged battery packs on hand for use
while other battery packs are being charged.
• Long use of a lithium ion battery pack gradually shortens the amount
of operating time it provides after each charge. This is normal for the
lithium ion battery pack and does not indicate malfunction. If you find
that the amount of time provided by your battery pack is too short, it is
probably time to replace it with a new one.
• Never try to use the DT-9021CHGEU or DT-9020ADP-G/DT-9020ADP-U
charger to charge any other type of battery pack.
• Avoid locations subject to vibration when performing the charge
operation.
• The battery pack discharges even when it is not loaded in the Data
Collector. Make sure you load the battery pack into the Data Collector
within at least one or two days after it is charged.
• It is recommended that a battery pack be removed from the DT-
9021CHGEU or DT-9020ADP-G/DT-9020ADP-U charger within about 24
hours after full charge is attained.
To charge battery packs using the Charger
1
Press the Data Collector’s Power switch to
turn off power.
2
Plug the charger into an electrical outlet, and
then attach the charger to charger connector
on the side of the Data Collector.
3
The Data Collector’s charge indicator lights
to indicate that the charge operation is being
performed. Charging is complete when the
charge indicator is no longer lit. It takes about
ten hours to achieve a full charge.
