2. There is no transducer detected.
If, at power up, there is no depth display and only a line is made from
top right to left your 128 may not be getting a signal from the
transducer. First turn the 128 on in S
IMULATOR MODE
to check for power
and processing ability. Then, ensure that an appropriate transducer con-
nector is positioned correctly in the collector plug is properly seated into
the 128. The 128 will work with the standard single beam transducer.
Finally, inspect the transducer cable from end to end for breaks, kinks, or
cuts in the outer casing of the cable. Also ensure the transducer is fully
submerged in water. If the transducer is connected to the unit through a
switch, temporarily connect it directly to the unit and try again. If none of
these items identifies an obvious problem, the transducer itself is
probably the problem. Be sure to include the transducer if returning the
unit for repair.
3. There is no bottom reading visible on the display.
There are a number of possible causes for this condition. If the loss of
bottom information occurs only at high boat speeds, the transducer
needs adjusting. If the digital depth readout is working but there is no
bottom visible on-screen, it is possible the depth range has been adjusted
manually to a range shallower than what is needed to display the
bottom. Also, in very deep water, it may be necessary to increase the
GAIN setting to maintain a graphic depiction of the bottom.
If you are using a transducer switch to connect two transducers to the
128 , ensure the switch is in the correct position to connect a transducer
that is in water. (If a trolling motor transducer is selected and the trolling
motor is out of water, no sonar information appears.)
If none of the above solve the problem, inspect the transducer cable from
end to end for breaks, kinks, or cuts in the outer casing of the cable. If
the transducer is connected to the unit through a switch, temporarily
connect it directly to the unit and try again. If none of these items
identifies an obvious problem, the transducer itself may be the problem.
Be sure to include the transducer if returning the unit for repair.
