Momentary Key
Function
DSP
This key selects an equalizer mode.
It is valid in the power-on status.
Each time this key is pressed, the equalizer mode is changed as follows:
FLAT
→
ROCK
→
CLASSIC
→
POP
On power application, the equalizer mode used when power was turned off last is restored.
The default equalizer mode is “FLAT”.
EJECT
This key is used to eject a disc.
It is valid when a disc is inserted.
Two EJECT keys are available. One is connected to the EJECT pin and the other is connected to
the momentary key matrix. These keys are the same in terms of function and can be used at the
same time. However, the EJECT key connected to the momentary key matrix is invalid in the
standby mode.
When the EJECT key is pressed, the disc is ejected.
If the disc is ejected in the CD mode, the radio mode is set.
However, the disc is not ejected if the front panel is closed.
If the CD mode is set at this time, playing is stopped and the radio mode is selected.
