Using the correct cu size is important for an accurate reading. A cu that is
too large will produce a reading that is lower than the correct blood pressure;
a cu 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.
Cuff Size Indicator On The Cuff
Our cu has an indicator which tells you whether you are using the correct
cu size or not. Place the cu on your arm (see Page E-6 to learn how to put
the cu on correctly) and if the Index Mark points within the Proper Fit
Range, you are using the correct cu size. If the Index points outside of the
Proper Fit Range, contact A&D Medical at 1-888-726-9966 (in Canada, call
Auto Control Medical at 1-800-461-0991) for more information on where to
obtain a cu replacement.
You must install 4 type AA (1.5 volt) batteries (alkaline batteries recommended),
or use the AC Adapter (see page E-11 for using the Monitor with AC Adapter)
and attach the cu 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 rst. Place the
batteries in compartment with positive (+) and
negative (–) terminals matching those indicat-
ed in the compartment. Be sure batteries make
contact with compartment terminals.
3. Replace cover by sliding it into the compart-
ment and gently pressing into place.
NOTE: Rechargeable batteries will not work
with this monitor.

blood pressure monitors are easy to use, accurate and digitally
display full measurement readouts. Our technology is based on the “oscil-
lometric 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 cu with each heartbeat.
The cu is inated until the artery is fully blocked. The ination speed is
maximized and the pressure level is optimized by the device. The monitor
takes measurements while the cu is both inating and deating. This results
in a faster measurement providing greater comfort to the user.
