You must install 4 type AA (1.5 volt) batteries (alkaline batteries recom-
mended), or use the AC Adapter (see page E-14 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:

Remove battery compartment cover by gently pushing down on
arrow and sliding cover forward.
2. Put in bottom row of batteries first. Place
the batteries in compartment with posi-
tive (+) and negative (–) terminals match-
ing those indicated in the compartment.
Be sure batteries make contact with com-
partment terminals.
3. Replace cover by sliding it into the com-
partment and gently pressing into place.

LifeSource® blood pressure monitors are easy to use, accurate and
digitally display full measurement readouts. Our technology is
based on the “oscillometric method” – 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 maximized and the pressure level is optimized by the device.
The monitor takes measurements while the cuff is both inflating and
deflating. This results in a faster measurement providing greater
comfort to the user.
