REMOTE CONTROL FUNCTIONS

The HK 3485 remote is capable of controlling six devices, including the
HK 3485 itself. The remote is preprogrammed at the factory to operate
most Harman Kardon DVD, CD and CDR players. Each time you wish 
to use the codes for any component, you will need to first press the
Selector Button for that component. This changes the button functions
to the appropriate codes for that product.

Phono:

Controls only the HK 3485 when a turntable is in use.

Video 1, 2 and 3:

Controls DVD players.

Tape:

Controls CD recorders.

CD:

Controls CD players.

AM/FM:

Controls the HK 3485 and its internal tuner only.

The functions specific to the HK 3485 are always available: Main Power
On and Off, Speaker 1/2, source selection, Mute, Sleep, Dimmer and
the Volume Controls.

Any given button may have different functions, depending on which
component is being controlled. Some buttons are labeled with these
functions. For example, the Track Skip and Fast Search Buttons are
labeled with the transport control icons printed on the buttons them-
selves, and these functions are active when a CD or DVD player is in
use. The Preset and Tuning indications appear above these buttons,
and those commands are active when the HK 3485’s tuner is in use.
See the Appendix for listings of the different functions for each type 
of component.

IR Transmitter Lens:

As buttons are pressed on the remote,

infrared codes are emitted through this lens. Make sure it is pointing
toward the component being operated.

Power Off Button:

Press this button to turn off the HK 3485 or

another device.

Power On Button:

Press this button to turn on the HK 3485 or

another device.

Speaker 1/2:

Press the Speaker 1 Button to enable the HK 3485 to

output audio to the speakers connected to the Speaker 1 Outputs, and
press the Speaker 2 Button to enable the Speaker 2 Outputs. You may
enable or disable both sets of speaker outputs simultaneously. This 
feature is a convenient way of hearing audio in more than one room at 
a time, although the same source material will be played through both
sets of speakers.

Source Selectors:

Press one of these buttons to select a source

device, which is a component where a playback signal originates, e.g.,
DVD, CD or the tuner. This will also turn on the receiver and switch the
remote to the codes that operate the source device.

NOTE:

The Video 3 source device may be connected to either

the front- or rear-panel connectors. To select the desired device,
press the Video 3 Source Selector repeatedly until the dot to
the left of the Video 3 Indicator in the Message Display lights
steadily (rear-panel connections selected) or flashes (front-panel
connections selected).

Preset Stations Selectors/Track Skip:

Press these buttons 

to select a preset radio station, or to change tracks or chapters on 
compatible Harman Kardon DVD and CD players.

Tuning/Fast Search:

Press these buttons to tune a radio station.

Tap the button briefly to tune one frequency step at a time, or press 
and hold the button to seek the next frequency with an acceptably
strong signal. The Fast Search function is available with compatible
Harman Kardon DVD and CD players.

Stop, Record/Pause and Play:

These transport controls have no

effect on the receiver, but are used to control compatible Harman Kardon
DVD and CD players.

Enter:

This button has no effect on the HK 3485, but is used as the

Enter key for compatible Harman Kardon DVD players, or the Random
Play Button for compatible Harman Kardon CD players.

Disc Skip:

These buttons have no effect on the receiver, but are used

with compatible Harman Kardon optical disc changers to skip to the
next disc.

FM Mode:

This button toggles between Stereo and Mono modes

when an FM station is tuned.

Preset Scan:

Press this button once to scan through the stations you

have previously programmed as presets. Each station will play for five 
seconds before the tuner skips to the next preset station. Press the button
a second time to select the current station. If no presets have been 
programmed, the 0 PRESET message will be displayed.

Mute Button:

Press this button to mute the HK 3485’s speaker and

headphone outputs temporarily. To end the muting, press this button 
or adjust the volume. Muting is also canceled when the receiver is
turned off.

Sleep Button:

Press this button to activate the sleep timer, which

shuts off the receiver after a programmed period of time up to 
90 minutes.

Dimmer:

Press this button to partially or fully dim the front-panel display.

Tuning:

The HK 3485 has two sets of Tuning Buttons for your conven-

ience. Press these buttons to tune a radio station. Tap the button briefly to
tune one frequency step at a time, or press and hold the button to seek
the next frequency with an acceptably strong signal.

Volume Controls:

Press these buttons to raise or lower the volume,

which will be shown in decibels (dB) in the Message Display.

Direct:

Press this button before using the Numeric Keys to directly

enter a radio station frequency.

Memory:

After you have tuned a particular radio station, press this

button, then the Numeric Keys, to save that station as a radio preset.

Numeric Keys:

Use these buttons to enter radio station frequencies

when using the tuner (after pressing the Direct Button), or to select station
presets.
