the Radar app and selecting the Power icon.
• A Quantum Radar will shut down after 30 minutes if neither a
wired (RayNet) , nor a wireless (Wi-Fi) connection can be made
to a MFD.
Radar not transmitting • Select Transmit for the relevant Radar scanner from the Radar
app.
Missing or incorrect Wi-Fi
credentials
• If using a wireless (Wi-Fi) connection, check that you have
entered the correct SSID and passcode for your Radar. Both
the SSID and passcode are provided on the Radar scanner’s
packaging, and are also shown on the serial number label on
the underside of the product.
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 product turned on, try flexing the cable near to
the display connector to see if this causes the product to
re-boot/loose 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 product to reset/turn off), replace if necessary.

if necessary. If the breaker keeps tripping or fuses keep
blowing, contact a Raymarine authorized dealer for assistance.
