Muting Circuit Test Mode
This mode is for confirming that the muting circuit operates properly.
Muting is activated only while the HOLD button is held pressed.
After a muting circuit test is started, the audio inputs/outputs are enabled and audio volume control using the INPUT LEVEL
and OUTPUT LEVEL controls is also enabled.
If the GAIN switch (CONNECTION selector switch) is switched in this mode, muting-ON is locked for about 2 seconds to
prevent GAIN switching noise.
For a complaint that noise is generated during switching of the GAIN switch (CONNECTION selector switch), perform
checking in this mode.
