Set-up, calibration and test modes are
intended for use by trained personnel or
service engineers only. Access to these

pass code is forgotten contact your local Honeywell
Analytics service department.
Note
Should the passcode be activated, the unit
will continue to detect gas and indicate
maintenance and instrument faults.
