Changing values in memory
Perform steps 1 through 5 in “Setting and storing data in memory” on p. 7.
Replacing the batteries
When the batteries run low, the “Lo” message will appear on the display window.
When this message appears, be sure to replace the batteries immediately, since weak
batteries will affect the accuracy of your measurements.
Your settings will not be erased from the memory when you remove the batteries.
Fresh batteries will last for about one year if a family of four uses the unit once every
day. The unit comes with 4 trial batteries. Their service life will be short.
