Enter the correct percentage if it is known and click Ok. If it is a
new battery pack complete the following steps:
1. Set the Percentage to 10 and leave the Battery Capacity
at 4000.
Note: The factory battery is 4000 mAh and so the default for the
Capacity box is 4000. To learn more about this setting read the
Battery Capacity section.
2. Tap on Ok to save the settings and to close the screen.
3. Plug unit into AC charger to charge the new battery.
Once the battery pack is fully charged, the gauging is
automatically set to 100%.
Battery Capacity
The capacity is the amount of energy a fully charged battery can
supply in milliamp-hours (mAh). The battery capacity of the
factory Field PC battery pack is 4000 so the default setting for the
battery capacity is 4000.
If you are using a different battery pack, check its mAh
rating commonly listed on the battery label. For optimum
performance, use battery packs with a 3000 to 4000 mAh
capacity. The higher the capacity the longer the charge is held.
Note: As a battery pack ages, operation time is reduced. The capacity
setting for an older battery pack can be adjusted downward to reduce
charging time and to more accurately represent the battery capacity.
Charging the Battery Pack
Recharging the NiMH Battery Pack
We recommend charging the Field PC battery pack when it is
not in use. The Field PC prevents the battery pack from being
overcharged if left plugged into the wall charger.
