Sleep Mode
To save battery run time, the device can be setup to automatically go into sleep
mode. If activated, the device will go into sleep mode if
- The device has been continuously activated for at least 8 hours
- The device has not detected any movement continuously for at least 2 hours
after the 8-hour minimum operation time has elapsed
- The device has not seen any alarm or readings other than 0 ppm (mg/m³)
during the 2 hours of no movement
Before going into sleep mode, the device will show a warning to notify the user
it will go into sleep mode if the device is not moved or no button is pressed.
During sleep mode, the device will be inactive, not measuring gas and not
displaying any readings. The device can be reactivated by either pressing the
button or deliberately moving the device so that a noticeable movement can be
detected.
