NOTES:
The LCD backlighting illuminates whenever any pushbutton is pressed. Backlighting will extinguish 15 minutes
after the last pushbutton press.
Pressing any two or three pushbuttons illuminates the LCD backlighting, displays all LCD segments, and
illuminates the VITAL IN, VITAL OUT, and VITAL AUX Output LEDs. The Output LEDs are illuminated in their
red phase as a means of confirming proper function of the detector’s Vital Output failure feature.
There are no internal switches or jumpers to set.
