BEFORE USE
Battery Installation and Replacement
Use ONLY 1.5V AAA size alkaline batteries for best performance
and optimal lifespan.
When the power is getting low, the monitor will remind you by dis-
playing two different messages:
1. Battery Symbol “ ” appears with your
test result to indicate that only 30 more
measurements (either glucose tests or
blood pressure tests) can be made be-
fore power runs out.
2. Error message “E-b” shows together
with ashing “ ” and “low” to indicate
that you must change the batteries be-
fore making any measurements.
