distance, or confidence. It displays units, if applicable.)

Whenever a loss of echo occurs, LOE flashes and the Reliable Echo indicator is replaced by
the Unreliable indicator. Before the Failsafe Timer expires, the letters LOE (Loss of Echo)
alternate with the reading every two seconds. Once the Failsafe condition is established, LOE
is displayed permanently. When a valid reading is received, the level reading display returns to
normal operation.
