HOW UA-851 WORKS

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.

BEFORE YOU START

You must install 4 type AA (1.5 volt) batteries (included), or use the optional
AC Adapter (see page E-11 for instruction on using the monitor with the
optional 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.
