To perform a test, insert a test strip as far as it will go. The meter will briefly perform system checks, then the display will turn on.
To access MAIN MENU, with the meter turned off, press and hold OK for two seconds.
Check that the screen shows solid black for two seconds. If it does, the display is working properly.
If the meter does not power on, try changing the meter battery.
CAUTION: If you see any light areas within the black start-up screen, there may be a problem with the meter. Contact Customer Care at 1-800-663-5521.
