HOW UA-789 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 (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:

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 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.

NOTE: Rechargeable batteries will not work with this monitor.
