.
The 1.6 ppm alarm value will then appear as an option in

Set cal due
Once the calibration gas values have been set correctly, click the MODE button three times in rapid succession to return to the main menu.
6.7 Set cal due
Once the Set Cal Due sub menu is reached, the Cal Due screen will be shown.
Hold the MODE button down to advance the counter. The number of days shown is the number of days that must pass following a successful calibration before the calibration due warning will be shown. The maximum length of time between calibrations is 180 days.
To disable the calibration due warning, set the interval to 0 days.
Once the calibration due interval has been set correctly, click the MODE button three times rapidly to return to the Main Menu.
