1。 DESCRIPTION
The lvlodel WS‑9 10 is an Auto lnflation Wrist Digital Blood Pressureヽ /1onitor.
The readings in each function are di」 tal diSplayed on 13 digits LCD panel.
STATUS INDICATION shows Palpatolγ ヽVave and BattelyヽVeak.
ERROR MESSAGE CODE includes Batte17 Ⅵ/cak,it is impossible to measure
the blood pressure accurately.
BAttERY POWER is monitored alwtts the batte17 rernnantis sho、 〜
咀on the displaげ .
AUTOMATIC AIR INFLATION iniates the cuffpressure by an mtemal dr pump.
AUTOMATIC AIR DUMP VALVE dumps the pressure in the cuff automatically
、vhen the rneasurement is over or error has been occurred.
AUTOMATIC POWER SHUT OFF;
The unit win autOmaicalサ turl■ Offifit is not operated for
about 3 1ninutes or IInore.

and、vTap the cuff tightly to the、vTist,leaving no space bet、 veen the cuff cloth.
In case you、 vear a、vTist watch on your left wnst,please、 vTap cuff after you put offit.
The posi■ on of me individual v′ hen being measured llnay be either lメ ng dOヽヽ m Or sitting.
In the sitting position hoM′ever make sure that the location on the left、 vTist to be
measured is about at the salnc height as thc heart and that the forearrlll is extended
naturally on the table and does not rnove
