Radar has a big center spot in the middle of the screen

General

Question

​My radar has a big center spot in the middle of the screen when on the lower ranges. What does this mean?

Solution

​This typically means that the radar's timing may need to be adjusted. Please refer to the radar installation manual which explains the procedure for "SWEEP TIMING ADJUSTMENT". If the "SWEEP TIMING ADJUSTMENT" does not help, please contact your local authorized Furuno dealer.
