This past weekend I went out to replace memory cards and batteries for my devices. Arriving at the song station, I flipped the switch from "Custom" to "Off", replaced SD card and batteries, and flipped switch back to "Custom" to return to the recording schedule. However, I received error messages (green + red blinking lights). I understand this error while switched on "Custom" signifies there is no time set or recording or no recording periods set, but this can't be correct. Three weeks ago I tested out each AudioMoth at my office to ensure it followed the desired schedule. Check. The following day when I deployed my devices I only deployed an AudioMoth if it blinked red OR green, indicating that the device was following my custom schedule. Check. But this past weekend I received this green + red error message during my first attempts to replace SD cards and batteries. This is evidently a user error, so I ask of guidance from the community.
Mahalo for the help.
