Control Head Maintenance

It is important to consider the following precautions when using your Humminbird® control head:

Chemicals, such as those found in bug spray and sunscreen, may cause permanent damage to the control head screen. Such damage is not covered by the warranty.

NEVER leave the control head in a closed car or trunk. The high temperatures generated in hot weather can damage the electronics.

Use the following information to keep the control head and screen clean.

Screen: To clean the control head screen, use a mild soap (such as a non-abrasive liquid hand soap) and warm water. Wipe the screen dry with a soft cloth. Be careful to avoid scratching the screen. If water spots remain, use a solution of water and vinegar.

WARNING! Do not use a chemical glass cleaner on the screen. Chemicals in the solution may cause cracking in the lens of the unit.

NOTE: Do not wipe the screen while dirt or grease is on the screen.

Control Head: If the control head comes into contact with salt spray, wipe the affected surfaces with a cloth dampened with fresh water.
