Basic Troubleshooting

The troubleshooting table below presents common problems and the means to restore normal
operation. If normal operation cannot be restored do not attempt to check inside the equipment.

Basic troubleshooting

If…

Then

neither echo nor fixed range scale appears

 

check battery voltage.

 

check fuse.

 

check battery terminal for corrosion.

 

check that power cable is securely

plugged.

no echo but range scale shows

 

check if display speed is set to "0."

 

check if transducer plug is firmly

connected.

echo appears but no zero line

 

check if range shifting is set to "0."

the equipment shows signs of low sensitivity

 

check if gain setting is suitable.

 

check for air bubbles or marine life

attached to transducer.

 

check if water is dirty.

 

bottom may be too soft to return proper

echo.

no water depth readout is shown

 

check if bottom echo is painted red or

reddish-brown.

 

check if bottom is displayed.

much noise or interference is present

 

check if transducer/transducer cable is too

close to engine.

 

check unit ground.

 

check if there are other echo sounders of

the same frequency nearby.

speed/water temperature indication* is absent or
unrealistic

 

check that sensor plug is securely

fastened.

position indication* is absent or unrealistic

 

check that sensor plug is securely

fastened.

 

check position-fixing equipment.

* Requires appropriate sensor.
