 Battery Installation and Replacement
Your monitor comes with batteries already installed.
When replacing, use ONLY 1.5V AA size alkaline batteries for best
performance and longest life.
Low Power Signal
The monitor will remind you when the power is getting low by displaying two
different messages:
1. Battery Symbol
appears while you perform tests. (Fig. 1)
This means it is about time to change the batteries although still
30 more measurements can be made.
2. Battery Symbol flashes by itself and the monitor cannot
perform any measurement.
(Fig. 2) This means you must change the batteries before
making any measurements.
