How to fix Furuno Marine Radar true motion presentation not working correctly?
If the true motion presentation on your Furuno Marine Radar is not working correctly, check that the setting of [Display Mode] in the [Display] menu is set to [True Motion]. Also, verify that the heading and position data are input and correct.
Why are the range rings not displayed on my Furuno 1945?
If the range rings are not displayed on your Furuno Marine Radar, adjust their brilliance on the [Brill/Color] menu. If this does not work, replace the associated circuit board or the SPU Board.
What to do if Furuno Marine Radar has no response when a key is pressed?
If your Furuno Marine Radar is not responding when a key is pressed, turn the power off and on. If you still do not get a response, the key may be damaged.
What causes Furuno Marine Radar antenna not rotating?
If the antenna on your Furuno Marine Radar is not rotating, the antenna drive mechanism may need to be replaced.
How to display range rings on Furuno 1945 Marine Radar?
If the range rings are not displayed, check that the setting of [Rings Brill] in the [Brill/Color] menu is set to other than [Off].
What causes brilliance adjusted but no picture on Furuno 1945 Marine Radar?

Why Furuno 1945 Marine Radar data and marks not displayed in transmit?
If data and marks are not displayed when transmitting on your Furuno Marine Radar, the SPU board may need to be replaced.
What to do if Furuno 1945 Marine Radar power is on, operated STBY/TX key to transmit, marks and letters appear, but no echo appears?
If the power is on, you've transmitted using the STBY/TX key, marks and letters appear but no echo is present on your Furuno Marine Radar, check that the antenna cable is securely fastened.
What to do if Furuno 1945 set GAIN to maximum with A/C SEA set at minimum, marks and indications appear but no noise or echo?
If the GAIN is at maximum and A/C SEA is at minimum, and marks/indications appear without noise or echo on your Furuno Marine Radar, check the continuity and isolation of the coaxial cable. If the issue persists, the IF amplifier may need replacement. Also, check the coax line for a fastened connection. If the connection is good, replace the SPU board.
What to do if Furuno Marine Radar marks, indications and noise appear but no echo?
If marks, indications, and noise appear but there's no echo (and the transmission leak representing your ship's position is absent) on your Furuno Marine Radar, check the magnetron current. Also, the modulator board or the SPU board may need to be replaced.
