Vive blood pressure monitor came with 4 batteries. The
monitor requires 4.
You do not need to read the instruction because getting the
monitor to work is just an easy 1 2 3 step.
Simply plug in the batteries on the back. Plug in the tub
that connects the armband to the monitor. The armband does not squeeze your arm
very tightly. Very slightly and it does or should not cause any pain or
discomfort. It was all very quick for me. The monitor showed the final SYS and
DIA for me with ease.
