Troubleshooting procedureUse the following table to identify problems and remedial actions.Symptom ActionNo connection can be made to thescanner.Ensure the data cable (if used) is connected at bothends and is in good condition.If using a Wi-Fi (wireless) connection to the scannerunit, check that you have entered the correct Wi-Fipasscode for the SSID that matches your scanner.Both the SSID and Wi-Fi passcode are provided onthe scanner packaging, and are also shown on theserial number label on the underside of the unit. Referto your multifunction display (MFD) documentation forfurther information.If the scanner unit has shut down, awaken it by usingthe Power Up Radar option in the Shortcut screen,accessible on your MFD by momentarily pressingthe MFD’s power key. The Radar unit will shut downwithin 30 minutes if a wireless (Wi-Fi) connection can’tbe made to a multifunction display unit (MFD).Ensure power supply thermal breaker has not trippedor fuse has not blown. If necessary, reset breaker orreplace fuse ONCE ONLY. If breaker keeps tripping orfuse keeps blowing, contact a Raymarine authorizeddealer for assistance.Ensure power supply maintains the correct voltagewhen the system is switched on.Ensure all products in the system have the correctsoftware. Refer to www.raymarine.com/software forthe latest software updates and the software updateprocedure for your product.If the Quantum™ Radome is connected to themultifunction display (MFD) via a SeaTalk hs or RayNetnetwork switch, ensure that:• All relevant equipment is correctly connected tothe network switch.• The network switch power supply is satisfactory.• The network switch is in good condition.• Network cables are securely connected and ingood condition.Displayed bearing is different to the truebearing.Carry out the bearing alignment procedure describedin the MFD Operations manual.Multiple Quantum Radars — more informationOnly 1 (one) Quantum™ Radar scanner can be powered at any one time, per networked system.• It is possible to have 1 Quantum™ + 1 NON-Quantum Raymarine Digital radar scanner powered atthe same time, on the same networked system.• It is NOT possible to have 2 Quantum™ Radar scanners connected via Wi-Fi powered at the sametime, on the same networked system, or a single standalone display. While it is technicallypossible to power up 2 Quantum™ radar scanners connected via Wi-Fi separately to 2 standalone(non-networked) displays, or 2 displays which each belong to a different RayNet network, thisconfiguration is NOT recommended. There may be Wi-Fi radio interference between 2 Quantum™radars operating at the same time.• It is NOT recommended to have 2 Quantum™ Radar scanners connected via RayNet powered atthe same time, on the same networked system. However, it is possible to have 2 Quantum™ radar70
