Erratic depth. Interference.
Transmitter is off.
If possible, try another receiver or
transmitter to identify the problem. The
approximate depth may be calculated
using the pitch information and the
distance between the FNLP and RNLP.
Receiver or transmitter malfunction.

Transmitter exits further to
the left or right than receiver
indicated.
Receiver was not held level when locating
transmitter.
Transmitter is being located by sweeping
receiver over it, looking for peak signal
instead of using the FNLP and RNLP.
Receiver’s antennas are out of balance.
The antennas can be balanced by
performing a diagnostic procedure over the
phone with DCI customer service
personnel or by sending your receiver to
DCI for testing/repair.
Read Locating Section,
which describes the
DigiTrak method for
finding the transmitter
using the FNLP and
RNLP. The DigiTrak
provides better accuracy
using the locate points.
All windows are blank.
Receiver has shut off to conserve battery
life. This occurs when the receiver has not
received a signal for 15 minutes. Simply
click the button to turn the receiver on (all
calibration data will be preserved).
Receiver will automatically shut itself off if
the calibration procedure is attempted
before the receiver has completed its start-
up process.
If the receiver will not stay on, the battery
may be dead. Test the battery to see if it
is fully charged.
