With the SoundEar 3 you also get flexible light settings, including day and night settings.

As a standard, the Noise Guide software can only show you LAeq1min in the measurement library but there is a small work around in order for you to view your measurements as LAeq1sec.
See this tutorial video on YouTube in order to find out how.
The internal memory of a SoundEar device is 16 MB.
The SoundEar USB drives have a memory of 8 GB.
To get an idea on the different functionalities of the SoundEar 3 software watch this demonstration video on YouTube
Make sure the USB drive is formatted (FAT 32) before using it, and make sure the USB drive is empty, before inserting it into your device.

The first time you connect your SoundEar 3 to your PC, Windows Update will try to find a driver for the software (this may take a while – around 5 minutes) – after this, Windows will “give up” and install a standard HID driver.
When the driver is installed, the device should connect to the software. You can check in your ‘Device manager’ in Windows to see if the ‘HID compliant system controller’ is installed – this would be your SoundEar 3 device.
