The FM reception is poor.
Use a 75-ohm coaxial cable (not supplied) to
connect the receiver to an outdoor FM antenna as
shown below. If you connect the receiver to an
outdoor antenna, 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 are connected securely.
Adjust the antennas and connect an external
antenna 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 32).
• Press DISPLAY so that the frequency appears in
the display.
