Missing or
incorrect Wi-Fi
credentials
• If using a wireless (Wi-Fi) connection, check that you have entered the correct

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