Power up troubleshooting

Operation.

1. Ensure that the radio is fully powered on, by holding the Power button for at least 3 seconds.

2. If your system includes a handset, it has its own independent power button, located on the top edge of the handset. Press and hold the button for at least 3 seconds, until the display lights up.

Blown fuse / tripped breaker.

1. Check the fuse, located inline with the power cable. Ensure that it has the correct rating (10 A), as an under-rated fuse can affect the power supplied to the radio. If the fuse has blown, replace with a new 10 A fuse.

2. Check the condition of relevant / additional fuses and breakers and connections, replace if necessary.

3. If fuse keeps blowing check for cable damage, broken connector pins or incorrect wiring.

Poor / damaged / insecure power supply cable / connections.

1. Check that the power cable connector is fully inserted into the unit and locked in position.

2. Check the power supply cable and connectors for signs of damage or corrosion, replace if necessary.

3. With the unit turned on, try flexing the power cable near to the display connector to see if this causes the unit 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 (when transmitting at 25 W), using a multi-meter, check for a high voltage drop across all connectors /fuses etc, and replace if necessary.

Incorrect power connection.

The power supply may be wired incorrectly, ensure the installation instructions have been followed.

Power source insufficient.

Check that your power supply (battery or distribution panel) is providing a minimum of 10.2 V to the radio when in standby, and also when transmitting at 25W.

Power supply and connection.

See possible solutions from ‘Products does not turn on or keeps turning off’ above.

Software corruption.

In the unlikely event that the product’s software has become corrupted, please try re-flashing the radio and the handsets with the latest software from the Raymarine website: www.raymarine.com/software

If you have a handset in your system (Ray63 / 73 / 90 / 91 only) with old software, you might need to put it into programming mode in order to update the software along with the radio. To do this, connect it and then press and hold the DISTRESS and PTT buttons together. While holding these buttons, press the Power button on the handset for 3 seconds. The handset backlight will start flashing. This means that the handset is now in programming mode. Follow the update instructions provided on the software download web page.
