To program different recording schedules for the BAR you'll need to download and install the Scheduler program.
Recordings can be programmed to start and stop at any date and can be scheduled to begin relative to sunrise or sunset thanks to the built in GPS in every BAR unit. You can easily configure the schedule to repeat certain recordings over a period of time to sub-sample a large block of time. Any number of specific recording patters can be created in a schedule file so you can have a different recording pattern, sample rate or channels for different times of the day or year.
Click the link above to download the installer. The user manuals for the Scheduler Software and the BAR are also included in the installation.
