      If your Onwa Marine Radio cannot be switched on, there could be a few reasons. The power cable might be broken, in which case you should replace or reconnect it. There might be a power supply problem, so you should check the power supply. Alternatively, the fuse may have blown, so replace it with a suitable rating fuse. If the fuse blows again after replacement, call for service.

      If you are unable to see AIS vessels around you on your Onwa Marine Radio, it might be because the KS200A/B is not switched on; in that case, switch it on. Another reason could be that the VHF antenna is not connected properly; try reconnecting it. Finally, there might simply be no AIS vessels in your vicinity; check again in a harbor.
