The
icon will appear when the batteries are exhausted and will need to be changed to ensure full functionality of the nVision. Continued use will fur-
ther drain the batteries to a non-operational state where the message “Replace Batteries” will appear across the display. From this state, the only operational
parameter will be the power button . After “Replace Batteries” appears, no measurements will be possible until the batteries are replaced, however, the
recorded data will be preserved.

CAUTION:
Never remove battery or USB power when Recording.

Do not remove or change the batteries in a hazardous atmosphere.
