Restore factory settings
Using this function deletes all stored settings and sets the device back to factory default settings. This
might be reasonable if the calibration has not been done properly, for example.
To reset the gas detector, press the “Mode” key until “ReFactSet” appears on the display. Now press the
“Enter” key and the “mode” key afterwards. Now you can select between ”Yes” and “No”. Confirm your
selection by pressing “Enter”. When “Yes” was selected, the factory default settings are restored after the
confirmation.

Lock/unlock
The gas detector has an automatic lock function to prevent the settings from being changed
unintentionally. If you wish to adjust the settings you have to unlock the device first. To do so, press and
hold the “Mode” key and the “Enter” key at the same time for 5 seconds. Now the device is unlocked and
you can change the settings. After 30 minutes, the device will be locked again. To activate the lock
function manually, press and hold the “Mode” and “Enter” key once again for 5 seconds.
Change the temperature unit
