What to do if Furuno Marine Radar true motion presentation not working correctly?
If the true motion presentation is not working correctly: 1. If you have a full keyboard, try pressing the MODE key a little harder. 2. Press the MODE key or operate the PRESENTATION MODE box until TM appears. 3. Enter the correct own ship speed. 4. Ensure that the speed and compass inputs are accurate.
Why Furuno Marine Radar tuning adjusted but poor sensitivity?
If the tuning is adjusted but the Furuno Marine Radar has poor sensitivity: * Turn off the 2nd trace echo rejector. * Clean the radiator face.
What to do if Furuno FAR-28 tracked target not tracked correctly?
If a target is not being tracked correctly on the Furuno Marine Radar, it may be due to poor definition of targets in sea clutter. Adjust the A/C SEA and A/C RAIN controls.
Why Furuno Marine Radar is properly tuned but poor sensitivity?
If the radar is properly tuned but the sensitivity is poor, consider the following possibilities: 1. The magnetron may be deteriorated, so check the magnetron current while transmitting on the 48 nm range. If the current is below normal, replace the magnetron. 2. The MIC may be detuned, so check the MIC detecting current. If it is below the normal value, the MIC must be tuned. 3. There may be dirt on the radiator face, so clean the radiator surface. 4. There may be water ingress to the waveguide or other feeder line, so remove the water from the feeder line. 5. The second trace echo rejection may be ON, so disable the second-trace echo rejector.
Why Furuno FAR-28 Marine Radar marks, indications and noise appear but no echo?
If marks, indications, and noise appear but there is no echo, the Tx high voltage protection circuit may have activated. Reset the power to restore normal operation.
What to do if Furuno FAR-28 Marine Radar range changed but radar picture not changing?
If the range is changed but the radar picture is not changing, try pressing the RANGE [+] and [-] keys several times. If that doesn't work, try turning the radar off and on again. If the issue persists with a keyboard-type control unit, replacement of the keypad may be required. If that does not resolve the issue, the SPU board may need to be replaced.
What to do if Furuno Marine Radar picture not updated or picture freeze?
If the Furuno Marine Radar picture is not updating or freezes, turn the power off and on again to restore normal operation.
What to do if Furuno FAR-28 Marine Radar power is on but nothing appears on monitor?
If the power is on but nothing appears on the monitor, the brilliance may be too low. For keyboard-type control units, turn the BRILL control clockwise to increase the brilliance. If you have a trackball-type control unit, press any one of the F1-F4 keys for five seconds to increase the brilliance to '50'.
