Troubleshooting

Before contacting Humminbird Customer Service, please read the following section. Taking the time to
review these troubleshooting guidelines may allow you to solve a performance problem yourself, and
therefore avoid sending your unit back for repair.
No Connection to the Radar Scanner
• Check the cable connections. Confirm the adapter cable (if used) is connected at both ends and is
in good condition.
• Ensure the power supply thermal breaker has not tripped or fuse has not blown. If necessary, reset
breaker or replace fuse (one time only). If breaker keeps tripping or fuse keeps blowing, contact a
Humminbird authorized dealer for assistance.
• Ensure power supply maintains the correct voltage when the system is switched on.
• If the Radar scanner is connected to the control head via an Ethernet Switch, ensure that:
• All relevant equipment is correctly connected to the Ethernet Switch.
• The Ethernet Switch power supply is satisfactory.
• The Ethernet Switch is in good condition.

and then power on all equipment.
