REMARKS: 1. Value obtained in the actual place
where the unit is installed may be
slightly higher than the values shown in
this graph because of the conditions of
operation, the structure of the building,
the background noise and other factors.
2. The test results were obtained from an
anechoic room.

To evaluate the noise level, the maximum value of the
measured sound pressure level is used. Read the value
at each frequency level (on horizontal axis, center of the
sound pressure band) from 63 Hz to 8000 Hz, and
select the corresponding maximum value indicated on
the vertical axis.
