LifeSource UA-767 - Manual (Page 4)

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).

SELECTING THE CORRECT CUFF
TUBE
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 (–) 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. 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.
