When Always-On mode is enabled, the device cannot be turned OFF with the ON/OFF button. There are three ways to power off the device when this mode is enabled:

When Go/No-Go mode is enabled, the device does NOT display a numeric gas reading. Instead, the device displays "OK" unless it enters a gas alarm state. When in gas alarm, the device displays "XXXX".

Although the gas exposure data is not displayed, that data is still recorded in the device's data log.

When Motion Alert mode is enabled, the device enters pre-alarm when no motion is detected for 20 seconds. This condition can be cleared by moving the device. After 30 seconds of inactivity, the full Motion Alert alarm is triggered. This alarm can only be cleared by pressing the button.

NOTE: When Motion Alert is enabled, it is not possible to enable Sleep mode.

When Persistent Alarm Mode is enabled, the device's red alarm LEDs continue to flash following a cleared gas alarm. The LEDs must be deactivated via an IR communication with MSA Link or with the MSA Galaxy GX2 automated test stand.

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

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.

NOTE: When Sleep Mode is enabled, it is not possible to enable Motion Alert.
