the  incoming  signal  passes  the  trigger  criteria.  Be  sure  to  have  your  trigger  settings 

properly adjusted when using compressed mode. Also try using Wrap viewing mode, this 

keeps the calls static on the display making it easier to see them. 

 

I have a lot of background noise or insects that are triggering auto recordings and 

messing up the compressed view. 

If  there  is  a  large  amount  of  low  frequency  noise  present  you  can  adjust  the  trigger 

frequency range to exclude signals below a certain frequency. For example, if there are a 

lot of insects below 10 kHz, you can set the minimum trigger frequency to 10 kHz and the 

auto record or compressed view will then ignore any signals outside that range. You can 

also try using the clip on directional cone attachment.

ve given a file a species label.  

To check if a file has a species label, open the File Directory. If a species label has been 

applied to the file, it will be displayed next to the file name.  

 

I want to watch the display in full spectrum, but record only zero crossing files. 

If  your  sensitivity  is  incorrectly  set,  you  may  see  bat  calls  live  on  the  full  spectrum 

spectrogram but not record them in zero crossing. For this reason, if you are viewing in full 

spectrum  you  need  to  record  in  full  spectrum.  However  you  can  easily  convert  the  full 

spectrum files to zero crossing in the free version of Anabat Insight.  

 

I know there are bats (can hear them) but I can
