Why is my Furuno 1835 Marine Radar power not turning on?
If your Furuno Marine Radar is not powering on, check the following: a blown fuse, the power connector to ensure it's fastened, the power cable connector for corrosion, the power cable for damage, and the battery for correct voltage output.
What to do if Furuno 1835 Marine Radar range is changed but radar picture does not change?
If you change the range on your Furuno Marine Radar and the picture doesn't change, try operating the RANGE key again. If that doesn't work and you cannot operate the RANGE key, replace the keypad. Alternatively, the SPU board may need replacing, or try turning the radar off and on.
What to do if Furuno 1835 Marine Radar picture not updated or picture freeze-up?
If your Furuno Marine Radar picture isn't updating or the picture freezes, check that the signal cables are fastened. If that doesn't solve the issue, the SPU board may need replacement. You can also try turning the radar off and on.
What to check if Furuno 1835 set GAIN to maximum with A/C SEA set at minimum shows marks and indications appear but no noise or echo?
If you set GAIN to maximum with A/C SEA set at minimum, and marks and indications appear but no noise or echo: 1. Check continuity and isolation of coaxial cable. 2. Replace IF amplifier. 3. Check coax line for fasten connection. If connection is good, replace SPU board.
Why is the sensitivity poor on my Furuno Marine Radar?
To address poor sensitivity on your correctly tuned Furuno Marine Radar, turn off the [2nd Echo Rejector] from the [Echo] menu. Also, clean the radiator. If the issue persists, check the magnetron current while transmitting on the 48 nm range; if it's below normal, the magnetron may be defective and require replacement. Finally, check the MIC detecting current; if it's below normal, the MIC may be detuned.
What to do if my Furuno 1835 Marine Radar range is changed, but the radar picture does not change?
If the range is changed but the radar picture does not change, try hitting the RANGE key again, or turn the display unit off and on.
What to do if Furuno 1835 Marine Radar range changed but radar picture does not change?
If the range is changed, but the radar picture does not change it may be that the RANGE key has faults, the SPU board needs replacing or there is a video freeze-up. Try to operate the RANGE key. If you cannot operate the RANGE key, replace the keypad. You can also replace the SPU board or turn off and on the radar.
Why Furuno Marine Radar power cannot be turned on?
If the power cannot be turned on for your Furuno Marine Radar, the issue may be with the mains voltage/polarity. Correct the wiring and input voltage. Alternatively, the power supply board may need to be replaced.
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.
