Troubleshooting—Continued
Symptom Possible cause Remedy
Tuner
Reception is noisy, inter-
mittent, and the FM STE-
REO indicator flashes?
Yo u’re too far away from the transmitter. Or,
your FM antenna is in the wrong position or
pointing in the wrong direction. Or, the sta-
tion’s signal strength is poor.
Use the [FM MODE] button to select mono mode
(page 31).
Adjust the position, height, and direction of your FM
antenna.
Install an outdoor FM antenna, preferably one with
many elements. Installing an outdoor antenna is a
specialist job, so contact your nearest dealer for advice
(page 23).
Reception is hindered by a
crackling noise?
Interference is being caused by fluorescent
lights being turned on or off or by passing cars.
Install an outdoor antenna as far away as possible
from nearby roads.
Adjust the position or direction of your outdoor
antenna.
Move your antenna as far away as possible from fluo-
rescent lights.
AM reception is hindered
by a buzzing noise, espe-
cially at night or with weak
signals?
Interference caused by electrical equipment,
including fluorescent lights.
Relocate your AM antenna.
Install an outdoor AM antenna (page 23).
AM reception is hindered
by a high-pitched noise?
Interference caused by your TV.
Move the AM loop antenna as far away as possible
from your TV.
Move the HT-R510 as far away as possible from your
TV.
FM reception and stereo
separation are poor even
though the TUNING and
FM STEREO indicators are
shown.
Ta ll buildings, mountains, or hills are causing
wave reflections that interfere with the main
signal.
Tr y an FM antenna with better directionality.
The tuner presets no longer
work?
The power cord has not been connected to a
wall outlet, or the power has been turned off for
an extended period.
Preset your favorite radio stations again (page 31).
The power cord must be plugged into a wall outlet a
few times each month in order to preserve the presets.
Recording
Sound can be heard from
the speakers, but it cannot
be recorded?
You cannot record from an AV component that
is connected digitally.
Connect the AV component using analog connections
(pages 10–19).
Yo u’re playing Dolby Digital or DTS source
material.
Although you cannot record Dolby Digital or DTS
surround channels, you can record the left and right
channels by connecting the source AV component’s
analog left and right outputs to a pair of analog inputs
on the HT-R510.
The wrong input source is selected on your
recorder.
Select the correct input source. See your recorder’s
manual for more information.
Others
The Late Night function
doesn’t work?
The Late Night function only works with Dolby
Digital.
“ DIGITAL” appears on the display when using a
Dolby Digital source (page 28).
The multi-channel inputs
don’t work?
The input signal format is set to Auto or Analog. Set the input signal format to Multich (page 29).
The AV component is not properly connected.
Connect the AV component’s 5.1 channel outputs to
the HT-R510’s DVD IN FRONT L and R, SURR L and
R, CENTER, and SUBWOOFER connectors
(page 13).
The listening mode changes
to Stereo when headphones
are connected?
This is normal. When you connect a pair of
headphones, the Stereo listening mode is
selected automatically.
• The HT-R510 contains a microcomputer for signal processing and control functions. In very rare situations, severe interference, noise
from an external source, or static electricity may cause it to lockup. In the unlikely even that this should happen, unplug the power cord
from the wall outlet, wait at least five seconds, and then plug it back in again. That should fix it.
•To reset the HT-R510 to its factory defaults, turn it on and, while holding down the [VIDEO 1] button, press the [STANDBY/ON] button.
“Clear” will appear on the display and the HT-R510 will enter Standby mode.
