Field Scan (Time Lapse) not working properly
1. Make sure that the stop and start times of Field Scan "A" and "B" do
not overlap (for example, do not set the start time of "B" to 8AM if the
stop time of "A" is 10AM).
Do not mix battery types-use ALL lithium or ALL alkaline.
Rechargeable batteries are not recommended.

CAUTION!: DO NOT USE the 1s Interval setting for Video at night
at a feeder or similar environment. It may cause the LEDs to
continue firing over a long period of time, which may overheat
and shorten the operating life of the internal electronic
components.
Do not mix old and new batteries.
