Retrain the Battery
The retrain the battery setting lets you fully discharge the
battery so it can be charged to its full capacity. Perform
this operation if you notice a decrease in battery life or
every three to six months as a best practice. Ensure the
375 Field Communicator is running on battery power
when this operation is performed.
During the operation, a message will be displayed and
the backlight will be set to its brightest setting to quickly
discharge the battery. The backlight, stand by, and
auto-off timers will be disabled. It may take up to several
hours to discharge the battery, depending on the amount
of battery power that remained when the operation
began.
If you tap CANCEL, the battery will stop discharging and
the backlight, stand by, and auto-off timers will be
re-enabled. The backlight setting will also be restored.
After the battery is fully discharged, do not use the 375
Field Communicator on battery power until it has been
recharged to its full capacity. However, you can use the
375 Field Communicator while it is being charged.
Touch Screen Alignment
The touch screen alignment setting lets you calibrate the
touch screen with the display. Tap the cross hairs firmly
and accurately at each location on the window. The
target will continue to move until the touch screen is
aligned. Touch screen alignment will be retained upon
start up.
