Troubleshooting
The batteries are not charging.
Make sure you are using the correct power supply and that it is connected to a working
power outlet.
My batteries don't last very long.
It is time to replace the batteries. See page 17.
My MicroField keeps turning off by itself.
The auto shut-off function may be enabled (the I/O symbol will be illuminated); see page
13. Or the batteries may be dead; try charging the batteries.
The unit is not turning off automatically.
Make sure the auto shut-off feature is enabled (the I/O symbol will be illuminated when it
is enabled). If the auxiliary cable is plugged into the AUX IN jack, the auto shut-off fea-
ture is disabled.
