the JR 347 has a Fuse near the module, verify if it's ok.

The backup battery only serves to retain the models if you remove the main battery or if the main battery is dead. You always want to keep the main battery charged for this reason. If the backup battery dies, you can still program and use the transmitter, but you may have to reprogram the plane every time you turn the radio back on. I used to send my radio in every 5 years to get the lithium battery replaced, but several years ago I decided to only have it replaced if it dies. I always store the radio with a charged battery in it and my x-347 has had the same lithium battery since 1999. Also my 10X has never had the battery replaced.

He says the screen lites up, so the fuse is fine.

Is the module seated correctly and are all the pins between the radio and the module in tact? Are the module and the receivers on the same frequency?

Thanks very much guys. I will check the pins on the module next. Best Regards, Captn
