LifeSource ® blood pressure monitors are easy to use, accurate and digitally display
full measurement readouts. Our technology is based on the “oscillometric meth-
od” – a noninvasive blood pressure determination. The term “oscillation” refers
to any measure of vibrations caused by the arterial pulse. Our monitor examines
the pulsatile pressure generated by the arterial wall as it expands and contracts
against the cuff with each heartbeat.
The cuff is inflated until the artery is fully blocked. The inflation speed is maxi-
mized and the pressure level is optimized by the device. The monitor takes mea-
surements while the cuff is both inflating and deflating. This results in a faster
measurement providing greater comfort to the user.

You must install 4 type AA (1.5 volt) batteries (alkaline batteries recommended),
or use the AC Adapter (see page E-11 for using the Monitor with AC Adapter)
and attach the cuff to the monitor before using it. To install batteries (or replace
them if the “Low Battery” symbol appears on display), proceed as follows:
