3-2 Configuring the MobileView Terminal
After making configuration changes and exiting the MobileView
Config Tool dialog, you will be prompted to write the registry changes
to Flash memory. You must do this to retain changes through power
cycles.
The following dialog appears.
Tap the Yes button to save the configuration to Flash memory.
Calibrating the Potentiometer
The Potentiometer tab allows calibration of the potentiometer.
To start calibration, tap the Calibrate button. The radio button
indicator prompts you to move the potentiometer to the:
• Min (Minimum) position, full travel in the counter clockwise
direction and then to
• Max (Maximum) position, full travel in the clockwise direction.
After moving the potentiometer to the Min and then the Max position,
tap the Calibrate button again to complete the calibration. The value
to the right of the Potentiometer slide bar should read 127 and the
slide bar pointer should be centered on the rightmost tick line.
To verify calibration, move the potentiometer knob to the Min and
Max positions. The slide bar value should read as a linear value from
0 to 127.
