Momentary Key
Function
BAND
This key selects the reception band of the radio.
It is valid in the radio mode.
Each time this key is pressed, the reception band is changed as follows:
FM1
FM2
FM3
AM1 (MW1, MW)
AM2 (MW2, LW)
When the radio mode is selected for the first time after power application, the FM1 band is received.
The MW or LW band is assigned to the AM2 band depending on the region for which the set is
intended.
For assignment of the reception band, refer to “3.1 Reception Bands”.
CD
This key selects the CD mode.
It is valid if a disc is inserted in the power-off status and radio mode.
If this key is pressed when no disc is inserted in the radio mode, a message indicating that no disc is
inserted is displayed for 3 seconds.
When this key is pressed, power is turned on, the CD mode is selected, and the CD is played from the
position on the disc that was played last.
The “repeat”, “intro”, “random”, and “program” playback modes are all off when the CD mode is
selected.
If the CD mode is selected for the first time after power application, the first track of the disc is played.
