Cause
• Mains cord’s plug is not plugged into
wall outlet.
• Antenna cable is not properly
connected.
• Antenna is not pointing in the right
direction.
• Radio waves are weak.
• Noise from a TV or interference in
the signals sent from the broadcast
station.
• Signals transmitted over the main
cord are modulated by the power
source frequency.
• Rear Panel EXTERNAL/INTERNAL
switch is set EXTERNAL position.
• Power connected amplifier not turned
on.
• Ensure that DAB coverage exists in
your area.
• At the time of publishing this manual
not many secondary services are
available, this will increase as more
DAB stations start broadcasting.
• DAB like other digital media is good
at producing quality audio from a low
level signal, however if this signal,
level is too low a “burbling” sound
can sometimes be heard.
Measures
• Plug the mains cord in properly.
• Connect the leads properly.
• Point the antenna in the right direction.
• Install an outdoor antenna.
• Turn off the TV.
• Change the position of the loop
antenna.
• Install an outdoor antenna.
• Insert the plug in the opposite direction.
• Install an outdoor antenna.
• Set the EXTERNAL/INTERNAL
switch to INTERNAL position.
• Connection leads to amplifier not
made correctly.
• Check that antenna is connected.
• If a secondary service station is
available, the secondary indicator “<<
>>” will be displayed next to the
station name.
• Use the ST-15S1’s “Tuning aid” while
repositioning your antenna to get the
maximum signal strength and reduce
this noise.
