Note: If the rotary selector switch is left in a position other than “0”
for more than 5 minutes, the digital display will begin to display
ammonia concentration. If this happens, return the selector switch
to the “0” position, then set the switch to the desired position. For
example, if you set the rotary selector switch to position “3” to
program the alarm set point, and if, after 5 minutes of inactivity the
display reverts to displaying ammonia concentration, move the
switch to “0”, then back to “3” to continue programming the alarm
set point.
Caution: Before closing the detector enclosure, be sure to
return the rotary selector switch to position “0” to
correctly display ammonia concentration.
