Note: This unit is equipped with an anti-volume-blast circuit which serves as an automatic
volume level adjuster so that you will not be deafened with sudden loud volume.
This system operates as follows. When [PWR] is switched on, the volume level is low. After that,
the volume level gradually returns to the level as the same as the one before turning off.
Anti-volume-blast circuit is not effective when volume level is lower than position 20 at the display.
