Momentary Key
Function
This key selects an adjustment mode of the electronic volume or initializes the status of the
electronic volume.
It is valid in the power-on status.
However, this key is invalid if telephone mute is turned on by the PMUTE pin (pin 47).
This key has two functions, as the VOL SEL key and the VOL CLR key. Which function is
selected depends on how long the key is pressed.
Key Pressed for:
Operation
Less than 4
seconds
Functions as VOL SEL key.
4 seconds or longer
Functions as VOL CLR key.
(1) Operation of VOL SEL key
This key is used to select the adjustment mode of the electronic volume.
The electronic volume can be adjusted in the following modes:
Mode
Function
Volume
Adjusts the volume of the main volume.
Bass
Adjusts the volume of the bass (low-frequency region).
Treble
Adjusts the volume of the treble (high-frequency region).
Balance
Adjusts the volume balance between the left and the right.
Fader
Adjusts the volume balance between the front and the rear.
VOL SEL/VOL CLR
However, the fader adjustment mode cannot be used if it is specified that the fader adjustment
function is not used by using the initialization switch “FADSEL”.
To perform equalizer processing by electronic volume, the bass adjustment mode and treble
adjustment mode cannot be selected if the equalizer mode is other than FLAT.
For equalizer processing by electronic volume, refer to “11.1 Electronic Volume Functions.”
If this key is pressed and released within 4 seconds while the electronic volume is not displayed, the
main volume is displayed.
While the electronic volume is being displayed, the adjustment mode is changed as follows each
time this key is pressed and released within 4 seconds.
Volume
→
(Bass
→
Treble)
→
Balance
→
(Fader)
The modes in parentheses ( ) are skipped if they cannot be selected because of the setting, and the
next adjustment mode is selected.
If an operation other than that to adjust the volume is performed or if no key is pressed for 5 seconds
while the electronic volume is displayed, the electronic volume display terminates.
