HOW UB-521 WORKS

LifeSource® Blood Pressure Monitors are easy to use, accurate and display clear digital measurements. Our technology is based on the “oscillometric method”. The term “oscillation” refers to the measure of vibrations caused by the arterial pulse and is a non-invasive method to determine blood pressure.

Our monitors examine the pulsatile pressure generated by the arterial wall as it expands and contracts with each heartbeat against the monitor’s cuff. This monitor measures your blood pressure while the cuff is inflating.

BEFORE YOU START

The UB-521 provides accurate readings on wrists with a circumference between 5.3" and 8.5" (13.5 cm and 21.5 cm).

The unit requires two "AAA" (1.5 volt) batteries to operate (alkaline batteries recommended). To install batteries (or to replace when "Low Battery" symbol appears), proceed as follows:

1..Slide the battery cover as shown to remove from the device.

2..Insert batteries into designated areas ensuring a correct match with positive (+) and negative (-) terminals.

3..Return battery cover by sliding back on to monitoring device.

NOTE: Rechargeable batteries will not work with this monitor.
