The origin is stored even when power is off, so it does not have to be reset every time
power is turned on. When the battery is replaced, the origin will have to be reset.
With “Set” flashing on LCD, a long press on the […SET ]button will move the
blinking to the readout digits in sequence. A short press on the […SET ]button will
