Product does not turn on or keeps turning off
Possible causes Possible solutions
Blown fuse / tripped breaker 1. Check condition of relevant fuses and breakers and connections, replace
if necessary (Refer to the Technical Specication section of your product’s
installation instructions for fuse ratings.)
2. 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 exing 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, using a multi-meter, check for high voltage drop
across all connectors/fuses etc, replace if necessary.
Incorrect power connection The power supply may be wired incorrectly, ensure the installation instructions have
been followed.
Power source insufcient
With the product under load, using a multi-meter, check the power supply voltage as
close to the unit as possible to establish actual voltage when the current is owing.
(Refer to the Technical Specication section of your product’s installation instructions
for power supply requirements.)

Software corruption 1. In the unlikely event that the products software has become corrupted please
try re-ashing the latest software from the Raymarine website.

however this will delete all settings/presets and user data (such as waypoints
and tracks) and revert the unit back to factory defaults.
