16.5 Sonar troubleshooting

Problems that can be encountered with your sonar module and possible
causes and solutions are described here.

Note:

Your product requires an external sonar module to be connected to enable
use of the Fishfinder app.

This troubleshooting guide assumes that you have a compatible transducer
connected to your external sonar module, which is correctly networked
to your display.

Possible causes

Possible solutions

Sonar disabled

Select

[Ping Enable]

from the Sonar app’s Sounder

menu.

Incorrect transducer
selected

Check that the correct transducer is selected in the
Sonar app’s Transducer menu.

Damaged cables

Check that the transducer cable connector is
fully inserted and locked in position.

2. Check the power supply cable and connectors

for signs of damage or corrosion, replace if
necessary.

With the unit turned on, try flexing the cable
near to the display connector to see if this
causes the unit to re-boot/loose power, replace
if necessary.

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 (this can cause the
Sonar applications to stop scrolling or the unit
to reset/turn off), replace if necessary.

Possible causes

Possible solutions

Damaged or fouled
transducer

Check the condition of the transducer ensuring it is
not damaged and is free from debris/fouling, clean
or replace as necessary.

Wrong transducer
fitted

Ensure the transducer is compatible with your
system.

External sonar
module: / RayNet
network problem.

• Check that the unit is correctly connected to

the multifunction display or Raymarine network
switch. If a crossover coupler or other coupler
cable / adapter is used, check all connections
ensuring connections are secure, clean and free
from corrosion, replace if necessary.

External sonar
module: Software
mismatch between
equipment
may prevent
communication.

Ensure all Raymarine products contain the
latest available software, check the Raymarine
website:

www.raymarine.com/software

for software

compatibility.

No depth reading / lost bottom lock:

Possible causes

Possible solutions

Transducer location

Check that the transducer has been installed in
accordance with the instructions provided with the
transducer.

Transducer angle

If the transducer angle is too great the beam can
miss the bottom, adjust transducer angle and
recheck.

Transducer
kicked-up

If the transducer has a kick-up mechanism, check
that it has not kicked up due to hitting an object.

Power source
insufficient

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 flowing. (Check your product’s Technical
specification for power supply requirements.)

Damaged or fouled
transducer

Check the condition of the transducer ensuring it is
not damaged and is free from debris / fouling.
