Inserting the memory card
The memory card contains the data and Handheld Software
required for operation.
1 -Install a pull tab on the memory
card
The handheld includes a number of pull
tabs that you can attach to various memory
cards. These pull tabs can make removing
memory cards easier.
For reliable operation, 3M recommends
using only SanDisk memory cards and
SanDisk memory-card readers.
2 –Insert the memory card
1Grasp the memory card with the label
side up.
2Push the pin-socket end of the memory
card into the memory-card slot until it
is completely inserted.
§Messages (such as loading the
database, etc.) appear on the
screen.
§If the memory card contains a
newer version of 3M software, a
dialog box will ask you if you want
to install the new version.
Above the memory-card slot is a
Secure Digital (SD) card slot that is not
used. A small plastic blank blocks the
SD slot. If the blank becomes loose,
push it back into place.
Database Errors
The handheld may display No Database or
Invalid Database messages.
§These messages are usually the result
of corrupted data on the memory card.
§If you see these messages, you may
have to reformat the memory card (See
Formatting amemory card on page
14.)
Data corruption can occur if you remove
the memory card from the memory-card
drive before a Data Manager export
operation is complete. You can also corrupt
data if you do not return to the Home
screen before you remove the memory
card from the handheld.

Battery use
Typical charge life
A fully charged battery typically provides several hours of use
before recharging is needed.
Checking the battery charge
The upper right hand corner of each task screen includes a
graphical battery charge indicator (battery gauge).
§The battery gauge shows how much of a charge remains in
the battery that is currently being used. (See Figure 10.)
§If the battery gauge shows less than 50% charge
remaining, you may want to replace the battery with a fully
charged battery and place the other battery in the charger.
Low battery warning messages
§The handheld warns you when battery power is low. You
should replace the battery if a “battery low” message
appears. (See Replacing the battery on page 18.)
§Handheld Software protects you from totally losing power
by requiring that the battery be changed or recharged when
the charge drops to a very low level.
