to ensure proper performance of the detector. The unit’s
operating range is 10.5 to 16.0 volts. If voltage is above 10.5, the
display will flash “
HI VOLT” until condition is rectified. If voltage
falls below 10.5 volts, display will flash “LOW VOLT”until
condition is rectified.

on the display confirms your selection.You’ll notice an “H”
