2. Select the transmitter (e.g. “Tx1: 3102”).
3. Select DUTY.
4. Select Present Depth.
5. Follow the on-screen instructions to input the present depth, which will then change

(If prompted to change the mode to “off-line”, use the Enter key).
6. Select “Quit” to exit to the previous menu.
F.2.4 Learn false echo
The transmitter can be manually told the live Distance (on page 199) 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 or AMS Device Manager

7: False Echoes (3102).
4. Select 6: Learn False Echo.
5. Wait three seconds while the transmitter learns to ignore the false echo.
