Comment
Low refers to low limit of the low voltage threshold.
Mid refers to middle limit of the low voltage threshold.
High refers to high limit of the low voltage threshold.
A silent low battery warning shows fault code  on
the display.
A single one-second low battery alarm beeps and the
display shows fault code . After five minutes, the
unit shuts down completely.
After two seconds below the limit, the unit shuts down
and the low battery alarm sounds a long beep
continuously for 30 seconds.
The over-voltage alarm beeps every second and the
display shows fault code  alternating with the
battery voltage. The status LED turns red and the
display screen is turned OFF within 30 seconds to
protect itself from excessive input voltage.
NOTE: Although the Freedom Xi incorporates over-
voltage protection, it can still be damaged if input
voltage exceeds 16.7 volts.
