 When no noise appears on the sonar unit after all of the 

above tests, then the noise source is probably cavitation. 

Many people make sonar installations which function per-

fectly in shallow water, or when the boat is at rest. In most 

cases, the cause of the malfunction is the location and/or 

angle of the transducer. The face of the transducer must be 

placed in a location that has a smooth flow of water at all 

boat speeds. Read your transducer owner’s manual or the 

Installation instructions in this manual for the best mounting 

position.

Make sure your unit has the latest software version. Go to the Software 

Update page on Lowrance.com. You can download updates for free.

Sometimes resetting your unit can solve unusual issues. Go to Lowrance.

com to access a list of reset procedures for Lowrance products. Locate the 

one that applies to the model you own. Try a Soft Reset first, this will return 

your settings to factory defaults. If you decide to try a Hard Reset, save 

any important stored data to an MMC or SD card or write the information 

down. The data will be deleted during this process.

If the radar, does not start up, try the following steps:

1. 

Verify head unit has the latest code that supports radar. 

2. 

Verify that the communication port is set to RADAR

3. 

 Turn the unit, radar and network off, then turn everything 

back on.  On power up the Radar should start initializing.  

Change over to the Radar Page and see if the unit is initial-

izing or giving the count down indication.  

   

a.  If you are getting a countdown: allow it to complete and 

then try to power on the  Radar.  If the Radar does not 

start rotating then the Radar will need to be sent in for 

service.
