Sound Level Meters – User Manual
4.12 Bluetooth
The instrument can be connected to a Bluetooth low-energy mobile device to allow control, live
view and overall measurement download. To connect to a device, download the dBactive
application from your smartphone’s app store. On the instrument, go to the ‘Advanced Options’
menu and select the ‘Bluetooth’ page. Enable Bluetooth.
The connection between the mobile device and the instrument requires pairing; this prevents
any unauthorised connections being made.
Run the app on the mobile device and scan for any devices. Select the instrument you wish to
connect to. A pair request will be asked for; the pair key is displayed on the Bluetooth page of
the instrument. Enter this into the mobile device.
The Bluetooth symbol in the information bar turns green when connected.
Please note: Bluetooth on the instrument is connected to Port 2, meaning that it cannot be
enabled at the same as the GPS function.
