7. My unit loses power at high speeds.
Your Tracker unit has over-voltage protection that turns the unit off when input
voltage exceeds 20 VDC. Some outboard motors do not effectively regulate the
power output of the engine’s alternator and can produce voltage in excess of 20
volts when running at high RPMs. The Tracker unit displays input voltage in the
Diagnostic screen. Use this readout to determine if the voltage exceeds 20 VDC.
8. The screen begins to fade out. Images are not as sharp as normal.
Check the input voltage using Diagnostic. The Tracker unit will not operate on
input voltages below 10 VDC.
9. The display shows many black dots at high speeds and high sensi-
tivity settings.
You are seeing noise or interference caused by one of several sources.
Noise can be caused by other electronic devices. Turn off any nearby elec-
tronics and see if the problem goes away. Noise can also be caused by the
engine. If engine noise is causing the interference, the problem will inten-
sify at higher RPMs. Increase the engine speed with the boat stationary to
isolate this cause. Propeller cavitation can appear as noise on-screen. If the
transducer is mounted too close to the propeller, the turbulence generated
can interfere with the sonar signal. Ensure that the transducer is mounted
at least 15" (38cm) from the prop.
