You must install 4 type AA (1.5 volt) batteries, 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:
1. Remove battery compartment cover by
gently pushing down on arrow and
sliding cover forward.
2. Put in top 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.
BEFORE YOU START
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.
