Is there a way to do a factory default reset?

SA UPB Quickstart guide
Factory Reset
All devices may be put into factory reset settings by doing a 5 tap, 10 tap and 2 tap. The 5 tap puts the device in set up mode, the LED will flash green. The 10 tap enters factory resets into the EPROM; the LED will flash red or blue, depending on the device. The2 tap puts the device back into operating mode. The usual next step is to 5 tap and attempt a set up from factory reset. Doubtful
