friendly, easy-to-follow format. Follow the steps and you will find it to be simple to use.

button and hold it for a second. The green or red light will come on.
• Green indicates your instrument is powered by 110V.

power back-up. If the power is interrupted, the DMII will continue recording using its
internal batteries.
The LCD screen will briefly display an information screen, then will finally switch to a SET-UP
screen.
