?HOW 767 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. The cuff is first inflated until the artery is fully blocked. Then, the monitor takes measurements while the cuff deflates. Our monitors examine the pulsatile pressure generated by the arterial wall as it expands and contracts against the cuff with each heartbeat.
BEFORE YOU START
You must install 4 type AA (1.5 volt) batteries 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
3.Replace cover by sliding it into
the compartment and gently pressing into place.

SELECTING THE CORRECT CUFF
Using the correct cuff size is important for an accurate reading. A cuff that is too large will produce a reading that is lower than the correct blood pressure; a cuff that is too small yields a measurement that is higher. With your arm hanging at the side of your body, measure the circumference of your upper arm
at the midpoint between shoulder and elbow.

To attach cuff, insert air connector at end of cuff tube into air socket on left side of monitor. Should you need to change the cuff size, the preset exhaust velocity rate may have to be adjusted (see page 11).
