  Having trouble with Wi-Fi on your Raymarine Marine GPS System? Here's what to check: * **Wi-Fi not enabled:** Make sure Wi-Fi is enabled on both devices and rescan for available networks. * **Wi-Fi automatically turning off:** Power cycle/reboot devices and rescan for available networks, as some devices may turn off Wi-Fi to save power. * **Device not broadcasting:** Try enabling broadcasting of the device’s network in the Wi-Fi settings. If that doesn't work, manually enter the device’s Wi-Fi Name/SSID and passphrase in the connection settings. * **Devices out of range/signal blocked:** Move devices closer together or remove obstructions and rescan for available networks.

Why is my Raymarine E70481 connection so slow?

  wmurphyAug 18, 2025
  If your Raymarine Marine GPS System connection is slow or keeps dropping, consider the following: * **Distance:** Move devices closer together, as Wi-Fi performance degrades over distance. For fixed installations like a Quantum Radar, enable the Wi-Fi connection on an MFD closer to the device. * **Interference:** Change the Wi-Fi Channel of the device you are trying to connect to and retry the connection. Temporarily switch off each device in turn until you have identified the device causing the interference.

What causes no depth reading on my Raymarine Marine GPS System?
- J
  James FrankAug 27, 2025
  If your Raymarine Marine GPS System shows no depth reading or has lost bottom lock, check these potential issues: * **Transducer location:** Ensure the transducer is installed according to its instructions. * **Transducer angle:** Adjust the transducer angle if it's too great, as the beam might be missing the bottom. * **Transducer kicked-up:** If the transducer has a kick-up mechanism, ensure it hasn't kicked up due to hitting an object. * **Insufficient power source:** Check the power supply voltage as close to the unit as possible under load. * **Damaged or fouled transducer:** Check the transducer for damage and ensure it's free from debris/fouling.

How to troubleshoot a Raymarine E70481 that won't turn on?
- J
  James WilsonNov 4, 2025
  If your Raymarine Marine GPS System isn't turning on or keeps turning off, there are several potential causes: * **Blown fuse/tripped breaker:** Check the condition of the fuses and breakers, replacing them if necessary. If the fuse keeps blowing, inspect for cable damage, broken connector pins, or incorrect wiring. * **Poor power supply cable/connections:** Ensure the power cable connector is fully inserted and locked. Look for damage or corrosion on the cable and connectors, replacing if needed. Flex the power cable near the display connector to see if it causes the unit to restart or lose power. Also, check the vessel's battery voltage and the condition of the battery terminals and power supply cables, ensuring they are secure, clean, and free from corrosion. * **Incorrect power ...
