automatically go into the Standby mode, as shown in
the 

Sleep Timer

C

, in the following order:

˙

front-panel displays and indicators. The first press of
the button will dim the displays to one-half normal
brightness and turn off the blue light inside the

î

Tuning:

Press these buttons to tune up or 

down through a selected frequency band. A brief 
(1⁄2-second) press of the button will manually tune 
to the next frequency increment, while pressing and 
holding the button for a longer period will automatically
tune to the next station with a signal strong enough 
for acceptable reception.

Direct Button:

Press this button to select a radio

station by entering its frequency using the 

Numeric

Keys

K

. (See page 14 for more information.)

˚

Numeric Keys:

These buttons serve as a 10-

button numeric keypad to enter tuner preset positions
or to tune stations directly.

¬

Auto Preset:

When the tuner and FM band have

been selected, this button may be used to automatically
program the tuner presets for all active stations. To start
the auto preset scan, press and hold the button. Note
that the 

Memory 

G

and 

Preset 

F

indicators will

flash. After a few seconds, the tuner will start to “look”
for active stations, as shown by increasing frequency
numbers in the 

Main Information Display 

B

.

Release the button and note that the tuner will briefly
stop at each active station and add a preset number to
the memory. If the FM tuner finds fewer than 30 FM
stations with acceptable signal strength, the Auto Preset
tuning will scan two more cycles or until the remaining
vacant preset memory spaces have been filled with
those found in the first scan. The scan will stop when
all 30 preset memory spaces have been filled or when
three scans through the band have been completed.

µ

Secondary Control Cover:

This sliding cover 

normally is in the “up” position so that it hides the 
secondary controls. To access these controls, place
your thumb on the small recessed area at the top
center of the control, and gently press the cover down
and toward you.

Ñ

This button is used to clear preset

memory information for the HK 3480’s tuner. (See
page 15 for more information on tuner presets.)

ø

memory position that stores a preset location for the
HK 3480’s tuner. (See page 15 for more information
on tuner presets.)

π

lower the HK 3480’s volume.

œ

Preset Scan Button:

Press this button to auto-

matically scan through the list of stations that are 
programmed into the HK 3480’s tuner memory. When
the button is pressed, each preset station will play 

for five seconds before the next station is selected.
Press the button again when the desired station is
heard, to stop the preset scan.

®

Mute Button:

Press this button to momentarily

silence the HK 3480.

ß

FM Mode Button:

Press this button when the

tuner is in use in the FM band to switch to monaural
reception if the station is weak and noisy. (See page 14
for more information.)

VMAx Selector:

Press this button to engage

VMAx processing of a stereo input. The 

VMAx Mode

Indicator 

A

will light, and you will notice a wider,

more spacious sound field. In order to obtain maxi-
mum benefit, you should be seated midway between
the two loudspeakers, and the same distance from 
the speakers as the speakers are from each other.
The speakers must be placed facing parallel and
evenly with each other so that their baffles are in 
the same plane. Press the button again to return to 
Stereo mode.

Ü

Enter Button:

This button has no function on the

HK 3480, but may be used as the Enter key for a
compatible Harman Kardon DVD Player or as the
Random Play button for a compatible CD Player. See
page 16 for more information on using the remote to
control other devices.

Tuning Up/Down:

When the tuner is in use, these

buttons will tune up or down through the selected fre-
quency band. A brief (1⁄2-second) press of the button
will manually tune to the next frequency increment, while
pressing and holding the button for a longer period will
automatically tune to the next station with a signal strong
enough for acceptable reception. These buttons will
also control Fast Forward and Fast Reverse (or Rewind)
for compatible Harman Kardon compact disc players/
changers.
