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). Change to monaural reception
(page 35).
• No stations have been preset or the preset
stations have been cleared (when tuning
by scanning preset stations). Preset the
stations (page 37).
