SOLUTION
Contact the Technical Assistance service or reprogram all of the data.
Check the connection to the antenna.
Check that if there is only one antenna it is connected to the lower
terminal (H1) on the interface.
Check the connection to antenna 1.
Check the connection to antenna 2.
Check the connection to the PROBE 1 output.
Check the connection to the PROBE 2 output.
Check the connection to the ERROR output.
Check the connection to the LOW_BAT output.
Check the connection to the AUX output.
Check for voltage at the ends of terminals 16 and 17 on
the interface unit terminal board.
Wait several minutes with the interface powered down.
""tuning"" LED on the receiver remains lit.
Change the battery
Give a start signal to reactivate the system.
Check the receiver cable and the relative connections
to the interface.
Move the cable from the antenna away from any power
cables. Change the operating channel.
Check the connection between the probe and the
transmitter.
Remove the probe from the transmitter, connect the
sprung contacts to one another and interrupt the
contact. If despite this the LED does not change status,
the transmitter is faulty. If it changes status, the probe is
faulty.
Check that the finger and crash protection pin (if used)
are tightened on the probe.
Tighten all of the screws.
Substitute the probe.
