Battery Life
Settings such as Auto Shutoff, Logging Interval, and Backlight Shutoff greatly vary battery life.
Standard . . . . . . . . . . . . . . . . . . . . . . . . 200 hours (typical) (1 reading per second recording, auto shutoff 20 minutes).
Ultra Low Power . . . . . . . . . . . . . . . . . 60 Days (typical) (2 installed modules, 1 reading per 5 minute recording interval with Auto Shutoff enabled
and 23° C ambient temperature).
USB POWER
The USB connected/powered icon
(
)
will become active when connected. The mini USB connection will power the nVision with and without the battery
pack installed. Since the power module consists of alkaline AA batteries, they will not be recharged by the USB device.
IP67 rating will be void if nVision is operated without 4AA power module in place. Therefore, if you desire to power the nVision with USB it is recommended to
install the 4AA power module (with or without batteries) to protect the reference recorder from the elements.
nVision under USB power consumes less than 100mA.
RESET
If for some reason the nVision needs to be reset, remove the battery pack and USB power for at least one minute, then reinstall. If the reset is
successful, the nVision will start operating without pressing the power button when the power pack is reinstalled.

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