Maintenance & Trouble Shooting Tips - Interphase Sonar Engine SE-200 Operation Manual

Maintenance
Below are some helpful tips for keeping your SE-200 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 Ext: 16.
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.
