OPERATION
The DOLBY H:BYPASS message indicates that Dolby Headphone
surround processing is in the default bypass mode, which delivers a
conventional 2-channel signal to the headphones.
Figure 54 – Headphone Jack
Press the Surround Modes Button on the front panel or the remote, to
switch to Dolby Headphone virtual surround processing, indicated by the
DOLBY H:DH message. Dolby Headphone delivers an enhanced sound
field that emulates a 5.1-channel speaker system. No other surround
modes are available for the headphones.
Source Selection
Press the front-panel Source List Button to scroll through the sources.
Each press of the button scrolls down the list that appears in the display
and on screen. See Figure 55.
Figure 55 – Source List Button
For direct access to any source, press its Source Selector on the remote.
The AVR 254 will switch to the audio and video inputs assigned to the
source.
The source name will appear in the upper line of the front-panel display.
If you retitled the source, the new title will appear. The audio and video
inputs assigned to the source will also appear briefly. The surround
mode will be displayed on the lower line.
Any other settings you adjusted in the Setup Source menu will also be
selected. You may view these settings in the Source Info menu at any
time by pressing the Info Settings Button.
VIDEO TROUBLESHOOTING TIPS:
If a video source is playing and there is no picture:
• Check that you have selected the source to which the
video input was assigned.
• Check the wires for a loose or incorrect connection.
• Check that you have selected the correct video input on
the display device (TV).
• Try pressing the Resolution Button on the front panel repeat-
edly until the correct video output resolution is selected and
a picture appears. You will be prompted to accept or cancel
the resolution change, as the CANCEL message will appear
on the front panel. Press the
¤
Button to view the ACCEPT
option, and then press the OK Button to complete the change
to the output resolution.
Additional tips for systems using HDMI:
• Turn off all devices (including the TV, AVR and any source
components).
• Unplug the HDMI cables starting with the cable between the
TV and AVR, and continuing with the cables between the AVR
and each source device.
• Carefully reconnect the cables from the source devices to
the AVR, and connect the cable from the AVR to the TV last.
• Turn on the devices in this order: TV, then AVR, then source
devices.
Using the Tuner
To select the AVR 254’s built-in tuner:
1. Press the Source List Button on the front panel repeatedly until the
desired tuner band is selected, or use the
⁄
/
¤
Buttons to scroll
through the source list.
2. Press the Radio Source Selector on the remote. Press this button
again to switch bands (AM, FM or XM).
A screen similar to the one shown in Figure 56 will appear, with the
band indicated in the middle of the screen. (The XM band uses a slightly
different screen.)
Figure 56 – FM Radio
Use the
⁄
/
¤
Buttons to tune a station (or channel for XM Radio).
The frequencies will be displayed in the front panel and graphically on
screen.
The AVR defaults to automatic tuning, meaning each press of the
⁄
/
¤
Buttons scans through all frequencies until a station with accept-
able signal strength is found. To switch to manual tuning, in which each
press of the
⁄
/
¤
Buttons steps through a single frequency increment
(0.1MHz for FM, or 10kHz for AM), press the Menu Button. The Radio
Modes line will be highlighted, and each press of the OK Button toggles
between automatic and manual tuning modes.
When an FM station has been tuned, toggling the radio mode switches
between stereo and monaural play, which may improve reception of
weaker stations.
A total of 30 stations (AM and FM together) may be stored as presets.
When the desired station has been tuned, press the OK Button, and two
dashes will flash in the front-panel display. Use the Alphanumeric Keys
to enter the desired preset number.
