Troubleshooting

We hope you’ll never get to this step. We all know bad things happen but do not despair! Cybermax FM+ is protected with a
fuse, SWR and TEMP protection. Fuse is the first thing to check. Make sure your coaxial cable leading to the transmitter or
antenna is not shorted or open. Next check the troubleshooting table on the next page. If you have problems you cannot
solve yourself, please see our website for contact information and support resources in our forum.

Fig 18: So, do you think you can handle it? We think you sure can!
