Note
• Write command works only in audio modes 2 to 6!
• Read and write options of this command refer to the active audio
mode.
• The range of <inCalibrate> is up to 65535 but will be suppressed to
32767. Values above <inCalibrate> = 65535 will cause a failure
• Changed values have to be stored with ^SNFW.
• Attention! When you adjust audio parameters avoid exceeding the
maximum allowed level. Bear in mind that exposure to excessive lev-
els of noise can cause physical damage to users!
• The default values are customer specific.
