This device allows you to play an audio message previously stored in its memory by transmitting it via ultrasound using DSB-SC (Double Side Band – Suppressed Carrier) modulation on Channel 1 (32.768 kHz).

It is powered by a 12V battery. Two LEDs indicate the device status: the green LED shows activity, while the red LED lights up when the battery voltage drops below approximately 8V. The device will continue to operate down to voltages of about 7V, providing approximately one month of autonomy.

To store a new message, connect the device to a computer using the provided USB cable. It will appear as a standard external mass storage device. Please note that the drive letter assigned may vary and may not always be F:.
