The Backlght (backlight) option enables 
the LCD backlight to activate automatically 
in low-light conditions.
If disabled, the backlight activates only 
when the detector is in alarm mode.
Note
In stealth mode, the backlight does 
not activate.
The detector is shipped with the Backlght 
option enabled.
The Confibeep (confidence beep) option 
provides continuous confirmation that the 
detector is operating properly. When confi-
dence beep is enabled, the audible alarm 
beeps once every 10 seconds.
Note
Confidence beep is automatically 
disabled during a low battery alarm.
The detector is shipped with the 
Confibeep option disabled.
If the Due-lock (calibration user lockout) 
option is enabled and a sensor is overdue 
for calibration upon startup, the passcode 
must be entered to access normal opera-
tion.
Note
If the correct passcode is not 
entered, the detector deactivates.
The detector is shipped with the Due-lock 
option disabled.
If enabled, the Latch (latched alarms) 
option causes the low and high gas alarms 
(audible, visual, and vibrator) to persist 
until they are acknowledged. Press C to 
acknowledge the alarm.
After the alarm is acknowledged, it reacti-
vates every 30 seconds until the gas 
concentration is below the setpoint.

option disabled.
