I received an error message on my radio it said BU ERROR. I'm thinking it is the back up battery. Anyone have any idea wear it is located in the radio.

The Futuba manual page 105 states the below, I beileve it is back up data not battery the post the error.


If the data is lost for an unknown reason, an audible alarm will sound and “BUERROR”
will be displayed on the LCD screen.
LCD screen:
Blink
Audible alarm:
Tone will sound (9 times), then
repeat.
Warning
When a backup error is generated,
immediately stop using the system
and request repair from the Futaba
Service Center.
If you continue to use the system, the transmitter
may malfunction and cause loss of control.
