OPERATION

• The HK 3490 does not switch the last-selected video source

when an audio-only source, such as Phono, CD or Tape/CDR,
is selected subsequently. It is not possible to view video while
listening to an audio-only source.

Using the Tuner (AM, FM and XM Modes)

The HK 3490’s built-in tuner may be selected in one of two ways
(see Figure 37):

1. Press the front-panel AM or FM Button. The front-panel FM Button

toggles between the FM and XM bands.

2. Press the AM, FM or XM Button on the remote.

Figure 37 – Tuner Input Selection

Radio stations may be selected in one of five ways (see Figures 38– 40):

1. If you know the frequency number, enter it directly by first pressing

the Direct Button on the remote, and then using the Numeric Keys. It
is not necessary to press the Direct Button when XM Radio is in use.

2. After you have programmed preset stations (see below), either enter

the preset number (1 through 30) using the remote or use the front-
panel Preset Stations Button to scroll through the list of presets.
When XM Radio is in use, first press the FM Mode Button repeatedly
to select Preset Search mode. Then use the

‹

›

Buttons to select

a lettered bank of presets. To select a numbered preset within a
bank, make sure the HK 3490 is in Preset Search mode, then use
the Numeric Keys, the

⁄

Buttons or the Preset Stations Buttons.

3. In Auto Tuning mode, press and hold the Tuning Buttons (front-panel

or remote) to scan in the chosen direction until a station with
acceptable signal strength is detected.

4. In Manual Tuning mode, with each press of the Tuning Buttons the

HK 3490 will tune the next frequency increment (0.1MHz for FM,
or 10kHz for AM) in the selected direction.

NOTE:

When XM Radio is in use, there are no auto or manual

tuning modes. Use the Tuning Button or

⁄

Buttons (only

when in All Channel Search mode) to select a channel. Press
and hold the button to search faster.

5. Press the Preset Scan Button on the front panel or remote to scan

through the previously programmed preset stations. The tuner will
pause for five seconds at each frequency before tuning to the next
preset. Press the Preset Scan Button again to select the current
station and stop scanning. When XM Radio is in use, this button is
used to change the display as follows: channel name and number,
category, artist and song title.

Figure 38 – Tuning a Station

When an FM station has been tuned, pressing the FM Mode Button will
switch between stereo and mono tuning, which may improve reception
of weaker stations. See Figure 39.
