Function
SRS
This key controls the SRS status.
It is valid in the power-on status.
Each time this key is pressed, SRS is turned on or off.
When power is turned on, the SRS status when power was turned off last is restored.
The default SRS status is off on power application.
TOP
This key is used to play the first track on the disc in the CD mode.
It is valid in the CD mode.
When this key is pressed, the playback modes, “repeat”, “intro”, “random”, and “program” are cleared,
and the first track on the disc is played.
TUNER
This key selects the radio mode.
It is valid in the power-off status and in the CD mode.
If this key is pressed and released within 4 seconds, power is turned on and the radio mode is set.
When the radio mode is set, the reception band of the radio, reception frequency, received preset
memory number, forced monaural status, and the on/off status of the local mode are the same as
those selected when the radio mode was selected the last time.
If the radio mode is selected for the first time after power application, the lowest frequency of the FM1
band is received, and no preset memory is selected.
At this time, both the forced monaural status and local mode are turned off.
