You must install 4 type AA (1.5 volt) batteries (included), or use the optional
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:
1. 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 positive (+) and
negative (–) terminals matching those indicated in
the compartment. Be sure batteries make contact
with compartment terminals.
3. Replace cover by sliding it into the compartment and
gently pressing into place.
NOTE: Rechargeable batteries will not work with this monitor.
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.
