The automatic audio tuning function automatically measures acoustic features of the location the product is installed in
as well as acoustic conditions such as positions to place the microphone and speaker, and tunes the acoustic settings to
the optimal level to suit the environment the product is used in.
If you have changed the installation location or installation position of the product, or if you have changed the number of
microphones or connected an external speaker, be sure to carry out automatic audio tuning before using the product.
The result of automatic audio tuning continues to be saved even after the power has been turned off.
■ Preparation
Make the following preparation to normally carry out the automatic audio tuning.
• Place the Control Unit, microphones, and external speakers (if used) as used actually, and make connections.
• Adjust the speaker volume so that four or more lamps light up on the level indicator.

While automatic audio tuning is active, the voice guidance is replayed to explain the procedure for carrying out automatic
audio tuning.
1 Hold down the tuning fork button

external speakers will not be enabled.
