through the presets quickly. In the
TUNE mode press these buttons to

TUNE/PRESET buttons while the
MEM indicator blinks, press MEMORY

again to store preset station. 
NOTE: When you store a frequency in
a memory location that already
contains a frequency, you replace the
previous frequency. If your receiver is
disconnected from AC power for more
than about 2 weeks, it loses all stored
frequencies.

Press this button, “Auto” will illuminate
in the display. Then press the
TUNE/PRESET button. The tuner will
automatically seek out stations in your
area that have enough signal strength
to be listenable. The tuner will stop on
stations until the SEEK/STEREO
button is pressed again.

Turn the VOLUME clockwise to
increase the volume and
counterclockwise to decrease it.

This window shows the state of
operation for easier control of the
receiver. It also contains the IR
Remote Sensor.
