Watch this short video to see how easy it is to set the date and time. Your meter comes with the batteries already installed and a preset time and date. You may need to change the time to match your time zone or, if you live in a state that observes daylight saving time, to reflect the time change. To change these settings: Press and release the On/Off button to turn the meter on. The flashing test strip symbol appears. NOTE: If this is the first time your meter has been turned on, it will automatically enter the set-up mode, and "Set-up" and the hour will flash on the display. Skip to Step 3 to change the time or, if the date and time are correct, press and hold the On/Off button to exit the set-up mode. To enter the set-up mode, press and hold the On/Off button for about four seconds. “Set-up” and the hour flash on the display. Press and release the arrows to decrease or increase the hour. Press and hold the arrows to scroll faster. Press and release the On/Off button to set the hour. The minutes flash. Repeat steps 3 and 4 to set the minutes, AM/PM, month, day and year. The flashing field is the one you are changing. Once you set the correct time and date, press and hold the On/Off button until the flashing test strip symbol appears.

Cleaning is simply removing dirt from the meter, while disinfecting refers to removal of most but not all, disease-causing and other types of microorganisms.

Clean and disinfect your meter once a week, or any time blood gets on the meter. You should also clean the meter before allowing anyone else to handle it.

The meter includes an additional internal battery that retains the time and date for up to 72 hours. So when the battery is changed, no memory is lost.

The meter uses 1 3-volt lithium coin cell battery (type CR 2032) found in many stores.

Make sure you have a new 3-volt, lithium battery, number CR2032, to insert. Open the battery door on the back of the meter, remove the old battery for at least 20 seconds, and press any button on the meter. Insert the new battery with the “+” sign facing out. Snap the battery door back into place. Press the on/off button, and the meter will beep. Setup and hour are flashing on the display. If the date and time are correct, press and hold the on/off button for about 4 seconds. Release the button, and you’re done.

Your battery should last for approximately 2,000 tests.
