update several Chorus recorders.

RECORDING MODES
You can choose between 5 different recording modes, outlined below. The LEDs on the inside
of the case will indicate which mode is selected, if no LEDs are lit, the recorder is in
Inactive
Mode
and will not record. Inactive mode is useful while configuring your recorder to avoid
creating unwanted recordings.
Most modes require a GPS fix on the deployment day, as the recorder automatically calculates
the sunset and sunrise times based on the current longitude and latitude.
If the recorder is left on, it will continue to record in the selected mode until the batteries run
out or the SD card becomes full.
Night-Only Recording Mode
The night-only mode is designed for efficient bat survey deployment, but may also be suitable
for other nocturnal animals. This recording mode will turn the recorder on 30 minutes before
sunset and off 30 minutes after sunrise. Night-only mode requires a GPS fix.
Dusk & Dawn Recording Mode
The dusk & dawn mode is designed for peak bird recording times and may be useful for other
crepuscular animals. This recording mode will turn the recorder on 90 minutes before sunset
