Installing and Removing Batteries
To remove the battery pack
Always make sure that Data Collector power is turned off before removing the battery pack.
Also, never remove the backup batteries while the battery pack is removed. Doing so will
cause all memory contents to be deleted.
1
Slide the battery pack compartment open
button in the direction indicated by the arrow
in the illustration, and open the cover.
2
Slide the battery pack in the direction shown
in the illustration and then remove it.
Important! • The power of the battery pack is depleted by testing prior to shipment
and by natural discharging during shipping and storage. Be sure to
use the procedures on page E-26 to charge the battery pack before
using the unit for the first time.
• Charge the battery pack as soon as possible when the buzzer sounds
intermittently to notify you that battery power has dropped.
• Always make sure that the Data Collector is turned off before opening
the lithium ion battery pack compartment cover. When the battery pack
compartment cover is opened, an alarm tone sounds. This is to
prevent the battery pack from being removed while the power is ON.
This can cause loss of memory data and system malfunction when
power is turned back on.
• Make sure that the battery pack never becomes shorted. A short can
cause damage to the battery pack.
• Repeated charges cause deterioration of the battery pack. If you find
that your battery pack does not provide enough operation even after
you bring it to a full charge, it probably means it is time to replace it.
• If you do not plan to use the Data Collector for a long time, protect
against running down the power of the backup batteries by fully
charging the battery pack.
