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 back-
ground noise and other factors.
2. The test results were obtained from an anechoic room.
NOTE
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.
