Possible causes and solutions
The Topline bus does not detect the radio receiver.
The bus cable is not or is badly connected to the terminal box : check the
plugging and the connection inside the terminal box. Check the state of
the cables : they must not show any sign of wear or cut.
The radio receiver emits an intermittent audible signal every 5
seconds.
The radio receiver stopped receiving the Topline Bus signal for more
than 10 seconds : the bus cable is not or is badly connected to the
terminal box : check the plugging and the connection inside the terminal
box.
The Multifonction transmitter no longer acts on your displays.
The Gyropilot transmitter no longer controls the pilot. The radio
system is no longer operating.

alarm.
- The radio transmitter is powered by a battery. The life time of the battery
is 1 to 3 years. It may need to be replaced.
- The transmitter is not paired with the radio receiver : perform the
pairing of the transmitter ( see chapter on initialisation).
- The radio receiver and its antenna do not receive the messages from
the transmitter. Check that the offset antenna is properly connected to
the receiver. Check that the antenna is not located near an object made
with metal or carbon.
