F.2.4 Learn false echo
The transmitter can be manually told the live Distance (on page 153) is being calculated from a
false target echo and that echo can therefore be ignored. If there is another false target echo,
repeat the learning process again. A maximum of four false echoes can be learnt.
Field Communicator
To ignore a false target echo:
1. From the Home screen, select 2: Configure.
2. Select 2: Manual Setup.
3. Select 6: False Echoes (MSP900GH)
or 7: False Echoes (MSP400RH).
4. Select 6: Learn False Echo.
5. Wait three seconds while the transmitter learns to ignore the false echo.
Note
When messages appear, take appropriate action if needed and press “OK”.
Mobrey MCU900 Series control unit
