battery backup for sony fs5

Is there an internal battery that keeps settings when the camera battery is detached?
My settings are being lost if I don't use the camera for a time and I have to assign again.
I don't see it in the manual and can't find where it might be on the camera.

yes there is, see manual Tip:

If you do not use your camcorder for about
2 months, the built-in rechargeable battery
gets discharged and the date and time settings
may be cleared from the memory. In that case,
charge the rechargeable battery and then set the
date and time again (p. 162).

On other Sony cameras they refer to "battery backup" but on the FS5 it is the "built-in rechargeable battery" probably why you couldn't find it.
