Huh? Are you saying it is normal to reprogram all the memories every 3

It's quite possible, even likely, if the tuner is not turned on during that
time. Depends on how the power switch works, but consider this:

If the internal power is on all the time, then it couldn't lose the memory
at all, the only backup needed would be in the event of momentary power
glitches.

I hope this is not the case and there is a provision to keep the memory
powered independent of the power switch state.
