button for approximately 2 seconds.

SLEEP
mode.
Releasing the

The instrument contains protection circuitry to prevent it from being turned
on when the battery voltage is below 1.7V.
There are two thresholds for the battery voltage:
•
The first is used to indicate low battery.
The low battery indicator will
blink when the battery voltage drops below 1.8V.
•
The second is used to determine when to terminate recording and
turn the unit off.
The shutdown threshold is when the battery voltage
drops below 1.7V.
