Lifetime Meters are displayed at the bottom of the screen. This is a resettable function. All PM3 and PM4 monitors may have their Lifetime Meters reset by performing a hard factory reset (see below). Depending on the age of the monitor (firmware version < 300) the Lifetime Meters can also be reset by removing the batteries for more than a few minutes. While Lifetime Meters may be an indicator of the amount of use or wear on a particular machine, it may be misleading if the Lifetime Meters are reset or if the monitor has been replaced during the life of the machine.
Hard Factory Reset
Hold down the UNITS and DISPLAY button and use a paperclip to depress and release the “Reset” button in the back of the monitor. Keep holding the buttons down for at least 7 seconds or until the display flashes “Setting Factory Defaults” shows briefly. Release the buttons.
Remove battery and USB cable if attached. Hold down the UNITS and DISPLAY buttons. Install battery. Keep holding the buttons down for at least 7 seconds or until the display flashes “Setting Factory Defaults” shows briefly. Release the buttons.
