INTRODUCTION
All bats in the suborder Yangochiroptera, and many in Yinpterochiroptera, use
echolocation to avoid obstacles and locate prey in conjunction with their eyesight.
Evolutionary history and differing ecological requirements mean echolocation calls tend to
differ between species, so they are often useful for identification. Echolocation calls vary
greatly depending on what a bat is doing, especially in response to how close the bat is to
clutter. Bat detectors detect the echolocation calls emitted by bats and produce audible
and/or visible images which reveal the presence of bats, their activity and useful features
of their calls. his gives us the opportunity to observe, identify, and study bats without
catching them.
he Anabat Walkabout is equipped with a broad-band microphone. he detector displays
and saves the recordings in both full spectrum and zero crossings analysis (ZCA) to make
them visible as sonograms (time vs frequency graphs). his manual contains the operating
instructions for the Anabat Walkabout, including advice for successful recording of bat
calls. Furthermore, this manual includes testing and troubleshooting procedures.
FEATURES OF THE ANABAT WALKABOUT
he Anabat Walkabout is designed for active bat detection with many advanced features
to aid in bat surveying. It is an all-in-one detector with a built in omnidirectional
microphone, detachable directional cone and colour touchscreen display. he Anabat
Walkabout utilises the Android operating system. Some of the key features of the Anabat
Walkabout include:

o save files, you can choose either Manual or Auto mode at the bottom of the display in
the Swipe Menu . Press your selection and it will be highlighted in yellow. In either mode,
when a file is saved, the last filename will be shown below the spectrogram. A red
recording circle will appear briefly near the top right corner of the display while the file is
being written to the SD card. You can save files in full spectrum (.wav) and/or zero
crossing (.zc) formats. o choose which format you would like to use, see SAVE AS .
Manual Mode
At any time while the microphone is on, you can press the Record button directly above
the scroll wheel on the side of the detector or the Save button in the swipe menu, and a
recording will be saved. o indicate a file has been saved, the detector will beep. In default
Manual Mode when the Record Button is pressed, the previous 10 seconds of data will be
saved to the SD card. For example, once a bat has flown past, you can press the record
button if you want to save the recording to a file. You can adjust this save time up to a
maximum of 20 seconds in Manual Record Length . You may choose to change this
default manual mode to Continuous Manual Recording Mode in Capture Settings. his

transferred to other detectors. o select a profile, press the Con iguration Pro ile button,
then choose your preferred profile or create a new one.
De ault Pro iles
he default profiles that come with the detector are locked. his means any changes you
make to these profiles will not be saved. In all the default profiles, the default sensitivity is
19, with manual recording mode selected, and compressed mode on.
Full Spectrum
he full spectrum profile will make the Anabat Walkabout operate as a full spectrum bat
detector. his profile will display a full colour spectrogram, based off a zero crossing
trigger, and will save files as .wav. he default audio mode will be auto-heterodyne, but
you can change this to another audio mode (however your change will not be
remembered once the detector is turned off).
Zero Crossing
he zero crossing profile will make the Anabat Walkabout operate as a zero crossing bat
detector. his profile will display in zero crossing, based off a zero crossing trigger, and will
save files as .zc. he default audio mode will be auto-heterodyne, but you can change this
to another audio mode (however your change will not be remembered once the detector
is turned off).
Basic
he basic profile will make the Anabat Walkabout operate as a heterodyne bat detector.
his profile will only show the basic mode display (no spectrogram), recordings will be
based off a zero crossing trigger, and will save files as .wav. he default audio mode will

his will split the display, with full spectrum at the top and zero crossing displayed below.
Basic Mode
Basic mode will not display a live spectrogram, only current tuned heterodyne frequency
and the peak energy frequency, as well as other measurements including temperature,
humidity and GPS status. his mode is useful for times where a live spectrogram could be
considered distracting. he Play TE button will play that last 10 seconds as time expansion
audio. he Auto Tune button, when checked, will automatically tune the heterodyne audio
to the peak energy frequency. This view can only be selected i you are saving iles as
.wav.

20
AUDIO
Please note: If you are unable to change the Audio, it may be because the profile is
locked. You will need to Creating a New Profile to unlock Audio in ENU SETTINGS.
Pitch Shifting
This mode compresses the ultrasonic spectrum down into an audible band by shifting the
pitch of the sound. Harmonic components and amplitude of the bat calls are kept in this
process. This is the recommended audio mode for listening to bats over the full frequency
spectrum as constant adjustments are not required for tuning or sensitivity. This audio
mode cannot be selected if viewing in zero crossing or basic mode.
Heterodyne
This mode shifts down a portion of the ultrasonic band into the human hearing range by
mixing the signal with an internal reference frequency. This reference frequency is adjusted
by the user to suit the frequency of bat calls of interest. The bandwidth of the heterodyne
mixing is about 5 kHz, so bats calling at a significantly different frequency to the reference
frequency will not be heard.
