Auto Power Off Function

To prevent unnecessary power consumption, this
instrument features an Auto Power Off function that
automatically turns the power off if the instrument is
not operated for a specified period of time. The
amount of time that will elapse before the power is
automatically turned off is set by default to 30 min-
utes.
To disable the Auto Power Off function:
Turn off the power, then press the [
switch to turn on the power while holding down the
lowest key. Make sure to hold down lowest key until a
message appears at the top left of the display after
pressing the power switch.
CAUTION
• Do not use the instrument for a long period of time at a
high or uncomfortable volume level, since this can cause
permanent hearing loss. If you experience any hearing loss
or ringing in the ears, consult a physician.
Intelligent Acoustic Control (IAC)
IAC is a function which automatically adjusts and
controls the sound quality according to the overall
volume of the instrument. Even when the volume is
low, it permits both low sounds and high sounds to be
clearly heard. For details, refer to page 59.
To set the time that elapses before Auto Power Off
is executed:
Press the [FUNCTION] button, press the CATE-
GORY [r] or [f] button several times until "Auto
Power Off" appears, then select the desired value by
using the dial.
Settings: OFF, 5, 10, 15, 30, 60, 120 (min.)
Default value: 30 min.
