Electromagnetic Interference (EMI)

EMI can disrupt or overload the communication circuits of the monitor system causing erratic display activity, and in severe cases a complete system shut down.

Phantom displays, such as meter RPM or ground speed when the machine is stationary, can be the result of system “noise” or EMI.

Common causes of EMI are:

• Operating close to “high tension” wires and broadcast towers.
• “Noisy” power supply.
• Monitor too close to radio antenna.
• Old radio cables used.
• Poor system ground.
• Monitor power not directly connected to battery.
• Radio power not directly connected to battery.
• Monitor wiring too close to radio wiring.
• Console not connected to controller with standard system cables.

Check causes of EMI and take corrective measures to overcome problems.
