Sony STR-DG720 - Manual (Page 88)

88 US
Tuner
The FM reception is poor.
• Use a 75-ohm coaxial cable (not supplied)
to connect the receiver to an outdoor FM
antenna (aerial) as shown below. If you
connect the receiver to an outdoor antenna
(aerial), ground it against lightning. To
prevent a gas explosion, do not connect the
ground wire to a gas pipe.
Radio stations cannot be tuned in.
• Check that the antennas (aerials) are
connected securely. Adjust the antennas
(aerials) and connect an external antenna
(aerial), if necessary.
• The signal strength of the stations is too
weak (when tuning in with automatic
tuning). Use direct tuning.
• Make sure you set the tuning interval
correctly (when tuning in AM stations
with direct tuning).
• No stations have been preset or the preset
stations have been cleared (when tuning by
scanning preset stations). Preset the
stations (page 58).
• Press DISPLAY repeatedly on the receiver
so that the frequency appears on the
display.

new ones, if they are weak.
• Make sure you select the correct input on
the remote.
