the memory contents. However the auto swing stop position and timer mode are cancelled, but the weekly timer setting is
restored with the holiday setting through all weekdays.
By resetting the clock and cancelling the holiday setting for each weekday after recovery of power, weekly timer setting
becomes effective.

cancelled regardless of whether the power failure compensation setting is valid or invalid.
