Maintenance
Your Humminbird fish finder is designed to provide years of trouble free operation
with very little maintenance. Use the following procedures to ensure your
Humminbird continues to deliver top performance.
MEGA 360 Imaging Maintenance
Use the following information to maintain the installation of the MEGA 360 Imaging
Transducer.
• Check the stability of the universal mount after initial use and periodically
thereafter to ensure that the installation remains stable.
• If your boat will be in long-term storage, remove the MEGA 360 Imaging pod
shaft from the bracket and store it in –40°F to 158°F (–40°C to 70°C), dry
conditions.
If the MEGA 360 pod becomes clogged with debris, you may remove the guard ring
to clean around the pod.
1. Remove the 3 screws on the guard ring.
2. Pull the guard ring straight off the pod. The guard ring is keyed to fit over the
screw holes, so do not twist it off.
3. Gently clean the MEGA 360 pod of debris. You can use mild soap and warm
water.
4. Replace the guard ring and screws. Hand-tighten only.
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.
