TEST TONE

You can emit the test tone to adjust the speaker output level.

CAUTION:

• The test tone will be heard for about three seconds after you

select “AUTO” or “MANUAL.”

the activated speakers in the following sequence:

the meter to C-weighting and slow averaging. Use the

a 75 decibel sound pressure level at the listening point.
