Maintenance

Your 300TX is designed to provide years of trouble free operation with virtually no maintenance. Follow these simple procedures to ensure your 300TX continues to deliver top performance.

∙If the unit comes into contact with salt spray, simply wipe the affected surfaces with a cloth dampened in fresh water. Do not use a chemical glass cleaner on the lens. Chemicals in the solution may cause cracking in the lens of the unit.

∙When cleaning the LCD protective lens, use a chamois and non-abrasive, mild cleaner. Do not wipe while dirt or grease is on the lens. Be careful to avoid scratching the lens.

∙If your boat remains out of the water for a long period of time, algae and other marine growth an reduce the effectiveness of the transducer. Periodically, clean the face of the transducer with liquid detergent. Pivoting the transducer up the bracket may allow better access for inspection or cleaning.

∙If your boat remains out of water for a long period of time, it may take some time to wet the transducer when returned to the water. Small air bubbles can cling to the surface of the transducer and interfere with proper operation. These bubbles dissipate with time, or you can wipe the face of the transducer with your fingers after the transducer is in the water.

∙Never leave the 300TX in a closed car or trunk- the extremely high temperatures generated in hot weather can damage the electronics.
