Minus sign (“–”) in bottom
window.
Receiver is set on ground for depth
reading, particularly at shallow depths, and
the ultrasonics are not reset. Reset the
ultrasonics.
Receiver has gone out of calibration.
Recalibrate using either 1-point or 2-point
calibration.
“Ultrasonic Function” in
Receiver Section
“Calibrating the Receiver”
in Receiver Section
Roll positions sticking or not
accurate.
Interference (squiggle in top left window
will not blink regularly).
If squiggle is blinking regularly, there may
be a transmitter or receiver malfunction. If
possible substitute a different receiver.
If you have a Mark III Receiver, conduct a
self-test for error code and failure
determination.
Transmitter has been overheated (temp
dot is black).

Receivers” in Operational

Not getting a solid depth
reading.
Interference.
The approximate depth may be calculated
using the pitch information along with the
distance between the FNLP and RNLP.

Bottom window depth/
distance flashes (with trigger
released).
Transmitter is being exposed to tempera-
tures in excess of 60ºC (140ºF). Verify
that temp dot is not black before further
use of transmitter.
Transmitter Section
Flashing squiggle (“~”) in
bottom window.
Transmitter has been exposed to tempera-
tures in excess of 60ºC (140ºF). Verify
that temp dot is not black before further
use of transmitter.
Transmitter Section
Solid squiggle (“~”) in bottom
window.
With 5.0 and later series firmware, the
receiver will display the transmitter’s
predicted depth at the FNLP in the bottom
window, along with a solidly illuminated
squiggle, when the trigger is held in. Pre-
5.0 series firmware will not do this.
