Factory/Field Test Menu
This menu is intended to check product functionality both at the end of the factory line and in the field. This
mode is entered by pressing and holding the
DOWN
key on the display board and Full/Half key on the keypad
for 10 seconds. Once the menu is entered, the unit will start with an LED test that lights all LEDs and segments
on the display. Navigation is done just like the User Menu. Refer to the table below for operation. Field Test Mode
exits after stepping through all modes only – there is not a timeout.
