Radar troubleshooting

Radar powered down:

If the scanner unit has shut down, awaken it by using the Power Up Radar option on the Shortcuts page, accessible on your multifunction display / chartplotter by momentarily pressing the power button.

Radar not transmitting:

Select Tx for the relevant Radar scanner from the Shortcuts page.

Damaged or disconnected Power cable / RayNet cable:

1. Check that the cable connectors are fully inserted and locked in position.

2. Check the power supply cable and connectors for signs of damage or corrosion; replace if necessary.

3. With the unit turned on, try flexing the cable near to the display connector to see if this causes the unit to re-boot/lose power; replace if necessary.

4. Check the vessel’s battery voltage, the condition of the battery terminals and power supply cables, ensuring connections are secure, clean and free from corrosion; replace if necessary.

5. With the product under load, using a multi-meter, check for high voltage drop across all connectors/fuses etc (this can cause the unit to reset/turn off), replace if necessary.

6. Check condition of relevant breakers and fuses, replace if necessary. If breaker keeps tripping or fuses keep blowing, contact a Raymarine authorized dealer for assistance.

Open Array power switch in OFF position:

Ensure Open Array power switch is in ON position.

Software mismatch between equipment may prevent communication:

Ensure all Raymarine products contain the latest available software, check the Raymarine website for software compatibility: www.raymarine.com/software

Bearing alignment adjustment required:

Carry out the Bearing Alignment procedure described in the latest version of the relevant LightHouse Operations manual.

Intermittent or poor power connection:

Check power connection at VCM-Series. (Voltage at input = 12 / 24 V, Voltage at output = 42 V)
