4.
Battery charging and data exchange can be done at the same time
or respectively. The Z-2121 Data Collector, however, is unable to
communicate with the host computer when placed on the cradle
without the battery attached to it.
5. The battery is always charged via the cradle. There are two ways
to charge the battery. First, take the battery out from the Z-2121,
and insert it in the back slot of the cradle for fast charging, as
shown in Fig 3, which takes about 3 hours before it is fully
charged; second, put the battery in the Z-2121, and place it on
the cradle, with the Z-2121 either on or off, for slow charging, as
shown in Fig 2. This will need approximately 6 hours. To
maximize the battery’s life span, it is recommended that slow
charging be adopted unless there is a need for fast charging.
6. While the battery is being charged within the Z-2121 on the
cradle, data can still be exchanged between the PC and the
Z-2121 via the DB-9 connector and the RS-232 port.
7. The battery should stay on the cradle (either with the terminal or
independently) for at least 12 hours before being used the first
time or after months of idleness.
