Maintenance

 

Below are some helpful tips for keeping your

 iScan V90 in top condition: 

 

1)  Keep your display clean and dry.  Occasionally wipe unit off with a damp cloth, but be careful not to scratch the 

lens covering the LCD screen.  For stubborn dirt, use a mild soap and a damp cloth.  NEVER USE SOLVENTS 

SUCH AS PAINT THINNER, ACETONE, OR GASOLINE TO CLEAN YOUR UNIT. 

 

2)  Occasionally clean the face of the depth transducer (sensing surface) and carefully remove any marine growth.  

Use a mild detergent, or 220 grit sandpaper, or crocus cloth to remove stubborn growth. 

 

3)  If the in-line fuse is blown, replace it with a 2 amp fuse.  NEVER REPLACE WITH A HIGHER AMP 

RATING !  If the fuse continues to blow, check the polarity of your 12 VDC power source.  If the polarity is correct, 

check with the 

Technical Service Department  at (831) 477-4944

 

4)  In order to protect your transducer from water damage, paint it with one of the following brands:  Interlux-

UltraCoat, Fiberglass Bottom Coat, Super Bottom Coat; Pettit-UniPoxy; Rule-Super KL, Gloss Dura Poxy.  

DO 

NOT use a solvent based paint. 

 

5)  DO NOT allow any solvents, i.e. gasoline, acetone, to come in contact with the transducer or head unit as 

these may dissolve the material. 

 

Troubleshooting Tips

 

PROBLEM 

POSSIBLE SOLUTION 

Unit will not turn on, or unit beeps but no picture appears.
 

 

 

Check fuse, battery voltage and power connections. 

Check your connections to the battery.   

Unit blows fuses.

 

Wiring is reversed or there is excessive current from the 

battery.  2 amp fuse required. 

Loses picture at speed.

 

Adjust the transducer angle or placement.  Make sure 

that  the transducer is installed in the area which has the 

least amount of water turbulence.  

Screen is full of noise, or has dots running through.
 

 

 

Reduce gain setting.  Review the section on interference.  

Check to see if other 200khz sounders are nearby. 

LCD darkens in sunlight after prolonged use.

 

Overexposed to sunlight - provide shading for display. 

Bottom slopes up/down.

 

Adjust the transducer angle or adjust the level setting. 

Digital water depth not working.

 

Increase your gain, and check that you can see the 

bottom in the DOWN mode. 

Controls do not respond. 

Unit will not change operating modes. 

Perform 

FACTORY RESET: Start with the unit off. 

Press and hold down the POWER and CURSOR keys. 

One the unit powers up, it is reset to the factory settings.
