Basic operations
Note: The lighting condition for the STANDBY lamp and for the
display differs depending on the power source.
* If no source is playing and no operation is done for about 4
minutes, “DC OFF” starts flashing on the display for about one
minute before the system turns off automatically (except when
the source is FM/AM or AUX, or when the microphone/guitar is
used).
Turning on the system
Press ON/STANDBY.
• When the system is operated on batteries or car battery (DC12V),
press ON/STANDBY on the system.
The STANDBY lamp goes off when the system is operated on AC
power.
The display comes on and the system is ready to continue in the
mode it was in when the power was last turned off.
Turning off the system
Press ON/STANDBY again.
The STANDBY lamp lights up when the system is operated on AC
power.
• When the AC power is used, the CLOCK indicator and the time
are displayed without backlighting.
Some power is always consumed even though power is turned
off (called standby mode).
To disconnect the system from mains (AC) supply completely,
unplug the AC power cord from the AC outlet. When you
unplug the AC power cord, the clock will be reset to “0:00” if
no memory backup batteries are installed.
You can adjust the volume level between 0 and 50.
Turn the VOLUME +/– control clockwise to
increase the volume or turn it
counterclockwise to decrease the volume.
Press VOLUME + to increase the volume or
press VOLUME – to decrease it.
When you press and hold VOLUME + or –, the volume changes
rapidly.
CAUTION:
DO NOT start playing any source without setting
the volume to minimum first, as a sudden blast of
sound can damage your hearing, speakers and/or
headphones.
For private listening
Connect a pair of headphones to the PHONES jack on the rear of
the system (see page 5). No sound comes out of the speakers.
Be sure to turn down the volume before connecting or putting on
the headphones.
