if the batteries are installed and
sufficiently charged.

Backplane Voltage Output Display
The MDC22 has a backplane voltage display to ensure
the power control is working properly. The reading
should be between 4.8 and 5.3 at all times. If the
reading is not at acceptable levels the MDC22 will
not work properly. Please ensure that you have the
proper input power levels in the appropriate AC/DC
inputs.
