Battery Life & Replacement
If the battery low symbol ( 
) appears on the display, replace all four batteries at the same time.
-When the battery low symbol ( 
) starts to blink, you will still be able to use the unit for a short while. You should replace the batteries with new ones ahead of time.
-When the symbol ( 
) remains lit, the batteries are exhausted. You should replace the batteries with new ones at once.Turn the unit off before replacing the batteries.
•Remove the batteries if the unit will not be used for three months or more.
•If the batteries are removed for 30 seconds, the Date/Time setting will need to be reset. See “2.2 Setting the Date and Time” for details.
•Dispose of batteries according to applicable local regulations.
Four new “AAA” alkaline batteries will last for approximately 1500 measurements, when used to take two measurements a day.
Since the supplied batteries are for monitoring use only, they may have a shorter life and not last for 1500 measurements.
