USER GUIDE
Charateristics
A keyholder frequency division bat detector with
amplitude control.
SIDE VIEW
FRONT VIEW
The Batango is a frequency division (FD) bat detector.
This device captures ultrasounds and divides the incoming
frequency, to allow it to be audible to human ears.
This is done by detecting the zero crossing signal and
synthesizing a digital wave, with the same amplitude but a
lower frequency.
In contrast to the majority of other frequency division bat
detectors, The Batango can be programmed for three
different dividing factors: 8, 10 or 16.
Moreover, it's possible to change the volume; all of these
functions are accomplished using a single button!

POWER
The device is turned on, with a single
short click.
Keeping the button pressed for a
few Seconds, the device (and LED)
turn off.
VOLUME CONTROL
There are four volume levels. By pressing a
short click, the number of blinks indicates
the volume level. So that a single short
blink represents the lowest volume, and
four blinks indicates the max. When the
max is reached, a further click will go
back to the lowest volume level.

DIVISION FACTOR
A double click will change the division factor. By default the
division factor is 10; so an incoming 50 khz ultrasound will
be converted to 5 khz. With a double click, the division
factor is changed to 16; and a single long led blink is visible.
A further double click, will change the factor
to 8; indicated by two long blinks. Another
double click reverts the setting back to 10,
followed by three blinks.
The Batango is completely digital, and
allows great flexibility due to the low
power and high frequency
microcontroller. All the incoming sounds, below 9 khz are
effectively blocked.
Due to the fact that it's a digital device, the sounds heard
with your headphones are against a silent background
(without noise or hiss).
This is a low power device, that uses less 3.5 mA, utilizing a
single coin cell battery. when in action.
If no ultrasound is captured, then the Batango enters a
Sleep mode, reducing current consumption.
When unused for 30 minutes, it enters into a deep sleep
mode, and power consumption is further reduced to only 10
µA.

HEADPHONES
Every headphones with a
standard 3.5mm jack connector
can be used with Batango.
There’s no internal loudspeacker.
CONSIDERATIONS
Heterodyne detectors and frequency division bat Detectors,
are not recommended for sound recordings; because the
original ultrasound has been modified and what we are
hearing, is not an accurate representation!
For good recordings, it's better to use a USB microphone
such as Ultramic200K or Ultramic250K.
