23.4 Radar troubleshooting

No connection can be made to the scanner

Possible Causes
Radar powered down
Radar not transmitting
Missing or incorrect Wi-Fi
credentials
Damaged or disconnected
Power cable / RayNet cable
Open Array power in Off
position
Software mismatch between
equipment may prevent
communication

Poor image quality

Possible Causes
High network bandwidth
usage may interfere with a
Quantum Radar connected
wirelessly

Displayed bearing is different to the true bearing

Possible Causes
Bearing alignment adjustment
required
Radar will not initialize (Voltage control module (VCM) stuck in "sleep mode"
Possible Causes
Intermittent or poor power
connection
Troubleshooting
Possible Solution
• If the scanner product has shut down, power it up by opening
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.
• Select Transmit for the relevant Radar scanner from the Radar
app.
• 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.
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.
• Ensure Open Array power switch is in the On position.
• Ensure all Raymarine products contain the latest
available software, check the Raymarine website:

Possible Solution
• Disconnect Wireless display and close the Wireless display
page.
• Disconnect other devices connected wirelessly.
Possible Solution
• Carry out the Bearing Alignment procedure.
Possible Solution
Check power connection at VCM. (Voltage at input = 12 / 24 V,
Voltage at output = 40 V)
for software compatibility.
