When you switch the power on the PartyQ will show and then it shows the current version number, e.g, to test the display
Important Note: The low battery indicator will be displayed every time the unit it powered on and booting-up. This does not mean you have a low battery, it’s just the LCD screen booting-up and displaying all of the characters for a second or two. If during the cook the low battery indicator comes on please change your batteries.
7.1.Power Interruption Recovery Feature with Internal Memory
Because of the internal memory, if there is a brief or sustained power interruption, such as a dead battery at any time while cooking with the PartyQ, the unit will automatically restart and continue to control your cooker at the same settings you originally set once the batteries are replaced.
