Self-Test for Mark III Receivers

Mark III Receivers have the capability of completing a diagnostic self-test to confirm proper operation. This test must be conducted without a transmitter and in an interference-free environment. The self-test procedure is conducted at start-up by clicking the trigger in a specific sequence.

1.Place a fully charged DigiTrak battery into the receiver and click the trigger once.

2.At the tone, quickly click the trigger 3 times (observe the number 3 in the bottom window). The test takes approximately 15 seconds to complete.

3.If no problem is detected, the receiver will sound 3 tones, and turn itself off.

4.If the receiver detects a problem, it will display an error code in the top left window accompanied by 2 long tones.

5.An error code of “001” indicates high background noise; move to an interference-free area and con- duct the self-test again.

For assistance with troubleshooting an error code call DCI.

Receiver Balance Check

If the receiver appears to be exhibiting a consistent left or right error, it is possible that the antennas in the receiver are out of balance. It is also possible to find the transmitter further to the left or right if you use only signal strength to locate the transmitter or if there is an interference source within proximity. The transmitter’s location (depth and left/right position) should always be determined using the front and rear negative locate points, not relying solely on peak signal.

To determine if the receiver’s antennas are in balance, com- plete the following test:

1.Place the transmitter on the ground and step out in front (or behind) about 10 to 12 ft (3 to 3.7 m) away and a little to the left or right side of the axis line that extends from both ends of the transmitter, as shown in the drawing.

2.Hold the receiver perpen- dicular to the transmitter with the trigger held in.
