Installing the Battery
Your BFQ-470 is powered by one CR2032, 3-volt battery. Before using the device, gently pull the
battery insulation tab to remove it. Use a paper clip to gently press the RESET button on the back of
the device. See “Resetting Your BFQ-470” for details.
Warning! Pressing the reset button with more than light pressure may permanently disable your BFQ-
470. In addition, resetting the BFQ-470 erases settings and user-entered information.
Replace the battery when the display dims.
Warning!! If the battery wears out completely, or if you take more than several seconds while
changing the battery, any user-entered information will be erased. You should always keep written
copies of your important information.
