Denis Watkins Posted February 5, 2018 Share Posted February 5, 2018 yes, all transmitters have onboard power enough for quite some time Quote Link to comment Share on other sites More sharing options...
DeeBee1 Posted March 18, 2018 Share Posted March 18, 2018 From the Futaba website FAQ: If I remove my transmitter battery will I lose all my data? Does my radio have a lithium battery to store all my programming, or how is this data stored? Do I need to service this memory in any way? For memory storage the 7C uses permanent EEPROM memory and does not have a lithium battery. Your transmitter battery may be removed safely for storage, cycling, or other reasons without loss of data. ----- In case you aren't aware, EEPROM memory is a type of memory that retains its contents when the power is removed and can be programmed and erased many times. It is basically the same sort of memory you'd find in an SD card in a phone or camera. I have a 7C and have changed the battery without problem, although I've noted down all the settings for the planes I have 'just in case'.
