11.2 Power up troubleshooting
Problems at power up and their possible causes and solutions are described here.
Product does not turn on or keeps turning off
Possible causes Possible solutions
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.
