3.1 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.
Product will not boot up (re-boot loop)

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:
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
DSC
and
TRANSMIT
buttons together. While holding these buttons, press
the
Power
button on the handset for 3 seconds. The handset
