What to do if the operation panel is not connected on Koden Marine Radar?
If the operation panel is not connected on your Koden Marine Radar, reconnect the operation panel connector.
What to do if speed over ground input failed on Koden MDC-2240 Marine Radar?
If the speed over ground input failed under use of ground stabilization on your Koden Marine Radar, confirm sensor operation for speed over ground and GPS conditioning.
What causes 'No video signal' on Koden MDC-2240?
A 'No video signal' error on your Koden Marine Radar may be caused by a front-end malfunction or IF Amp malfunction. Check and repair the front-end circuit and IF amplifier.
Why did my Koden Marine Radar change to relative vector?
Your Koden Marine Radar changed to relative vector because heading related signals cannot be input in EPA/ATA [True] vector mode. Verify the availability of required heading signals.
Why did my Koden Marine Radar change to relative bearing?
Your Koden Marine Radar changed to relative bearing because heading related signals cannot be input in EBL true bearing mode. Make sure all required heading signals are available.
What happens if I attempt to input marks exceeding the allowed limit on Koden MDC-2240 Marine Radar?
If you attempt to input marks exceeding 50 on the chart of your Koden Marine Radar, limit the number of marks being input to 50 or fewer.
Why does Koden MDC-2240 display 'No own ship information'?
The 'No own ship information' message on your Koden Marine Radar appears because heading, speed, and latitude/longitude signal cannot be input during chart display. Ensure that heading, speed, and position data are correctly input.
What to do if Koden MDC-2240 Marine Radar shows 'No signal on Speed'?
If your Koden Marine Radar indicates 'No signal on Speed', ensure VHV, VHW, VBW, VTG, RMC, or RMA signals are being received.
How to fix 'No signal on Heading' on Koden MDC-2240?
If you are getting a 'No signal on Heading' message on your Koden Marine Radar, confirm the reception of HDT, HDG, HDM, VTG, RMC, or RMA signals.
What happens if there is no speed input on Koden Marine Radar?
If you attempt to acquire ATA without speed input on your Koden Marine Radar, ensure you input speed to acquire ATA.
