The Noise Limit
The noise limit is selectable to suit the function of
the room. It can be set in 5 dB steps to a level between
40 and 115 dB(A) using the control on the back.
The yellow lights come on just before the limit is reached.
As soon as the limit is exceeded the red center lights up
and the word WARNING is displayed.
For most hospital and medical center applications, the
level will be set to between 50 and 65 dB, depending on
the type of room being monitored. |
