Thank you for choosing a Harman
Kardon Audio/Video Receiver.

Your new Unit is an exceptionally
well-engineered product that will give
you years of superb performance.

It is essential for shipping should you
move, or in the event the unit ever
needs repair.

This reminder is provided to call the CATV system installer’s
attention to Article 820-40 of the NEC that provides guidelines
for proper grounding and, in particular, specifies that the cable
ground shall be connected to the grounding system of the
building, as close to the point of cable entry as practical.

receiver stops at each preset location
from 1-30 that has been entered in
memory. Hold the button down to skip
through the presets quickly. In the
TUNE mode press these buttons to
change selected frequencies.

Use this button to store an AM or FM

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
