D value when the protection function was activated
A
t the same time that the protection history is indicated, the
A
D value when the protection function was activated is
indicated in binary code (
B
CD) using the
“
INPUT
”
indicators. (Fig. 9)
BASS:
A
D value for the most recent protection function
TREBLE:
A
D value for the 2nd most recent protection function
BALANCE:
A
D value for the 3rd most recent protection function
LOUDNESS:
A
D value for the 4th most recent protection function
* When checking the
A
D value when the protection function was activated, the
“
VOLUME
”
knob will automatically
move to the position when the protection function was activated. Do not operate any knob while this knob is moving.
* For functions If protection L/Rch or U
