You must install 4 type AA (1.5 volt) batteries not included (alkaline bat-
teries recommended) 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 for-
ward.
2. Put in bottom row of batteries first. 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.
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.
