3.14.1.2 Display Timeout
This is a feature that allows the end user to adjust how quickly the screen menus timeout (revert to main
menu).
NOTE: A long press (>1 second) will back up the menu one level (serial number J01402 and above),
This allows adjustment of the timeout screen and can be configured from 1 second to 30 seconds by turning
the inner knob.
For a user whom is unfamiliar with the product, this will give them enough time to learn the system. After
becoming more familiar the user can speed up the menu screen timeout as desired.
Cycle the PMA450 power to exit setup screen.
