INDEX
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 will produce a reading
that is higher than the correct blood pressure. With your arm
hanging at the side of your body, measure the circumference of your
upper arm at the midpoint between the shoulder and elbow.
To attach cuff, insert air connector at end of cuff tube into the air
socket on the left side of the monitor.
Cuff Size Indicator On The Cuff
Our cuff has an indicator which tells you whether you are using the
correct cuff size or not. Place the cuff on your arm (see Page E-7 to
learn how to put the cuff on correctly) and if the Index Mark ▲
points within the Proper Fit Range, you are using the correct cuff
size. If the Index points outside of the Proper Fit Range, contact
A&D Medical at 1-888-726-9966 (in Canada - 1-800-463-5414) for
a cuff replacement at an additional cost.
SELECTING THE CORRECT CUFF SIZE
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
LifeSour ce™ 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.
