The D240X is also a backlit sensor, with large numbers and a digital display précisLes frequency and volume controls are on the side of the device, which makes it easy and quick to adjust. By using stereo headphones, the superposition signal is heard on the left channel and the time expansion signal on the right channel. When the built-in speaker is used, a switch selects either the time expansion signal or the heterodyne signal.
A digital recorder can be connected to D240X record calls for extended time to study the computer. If the recorder has a recording mode "voice activated", we get a fully automatic bat registration system, which can be left on the ground for unattended recording of bat calls .
