If the instrument didn’t successfully level, there are several things you can try.

from the client’s head.
• Make sure the microphone set is securely plugged into the remote module.
• Check the calibration of the loudspeaker and microphones. See Appendix B.
• Check the noise level in the room. It may be necessary to change or correct
the sound field environment.
• Make sure the remote module and speaker cable are securely plugged into
the main electronic module.
See Section 2.8 for details on the leveling status and troubleshooting the leveling
