NoiseMeters SoundEar II Noise Activated Warning Sign
Setting the Noise Limit
You can set the SoundEar II to provide a visual warning, consisting of a
flashing read light, to one of 16 different noise limits ranging from 45 to
115 dB(A).
Use the red wheel at the bottom of the device to select the desired noise
limit. 
Mounting and Powering
The microphone is located at the bottom of the sign, ensure that it is not
covered up. Also avoid mounting close to absorbing materials.
With a power outlet nearby, mount the sign on the wall using an 8-9mm screw at
a height of 150-200cm. Ensure it is securely mounted. A VESA mount is also
available for more secure or corner mounting.
