Loading the large-capacity battery pack into the Handheld Terminal
After loading a large-capacity battery pack, you need to use the special large-capacity
battery pack cover in place of the standard battery cover.
Attachment and removal of the large-capacity battery pack cover are the same as
attachment and removal of the standard battery pack cover.
Important !
• When replacing the battery, make sure you do not leave the Handheld Terminal
without a main battery for more than about 10 minutes. Doing so can cause data
in Handheld Terminal memory to be deleted.
• When replacing the battery, be sure you carefully follow the proper procedure
as explained in this manual.
• Never try to use any type of battery other than the one that is specified for this
product.
