What to do if the control panel of my Onwa KR-12X8 does not light?
If the control panel does not light, the battery may have discharged. Try adjusting the control panel backlighting on the Function menu. Also, check the fuse.
What to do if nothing appears on the display or the display contrast is poor on my Onwa KR-12X8?
If nothing appears on the display or the display contrast is poor, try adjusting the brilliance.
What to do if neither noise nor targets appear on my Onwa Marine Radar, but indications and markers do?
If neither noise nor targets appear, but indications and markers do, check the signal cable for damage.
Why is the sweep not synchronized with antenna rotation on my Onwa KR-12X8 Marine Radar?
If the sweep is not synchronized with antenna rotation, the problem may be in the antenna unit. Request service.
What to do if characters and indications are abnormal on my Onwa Marine Radar?
If characters and indications are abnormal, have a qualified technician check the set.
