1.DESCRIPTION
The ModelヽVS‑540‑15 is an Auto lnflationヽ Vst I)igital Blood Pressure Monitor.
The readings in each function are digital displεり
ed on 7 digits LCD panel.
STATUS INDICATION shows Deflation,Inflation,Palpatory Wave and Battely Weak.
ERROR MESSAGE CODE includes Battely Weak,itis impossible to measure the blood pressure
accurately when ERROR MESSAGE CODE appears.
BATERY POWER is monitored when the unitisturned on and a、 varning、、■u be displaり ed
ifit is too、 veak.
AUTOMATIC AIR INFLATION inflates the cur pressure by an intemal alr pump.
AUTOMATIC AIR DUMP VALVE dumps■ le pressure in the cuff automatically when
the rneasurementis over or error has becn occurred.
AUTOMATIC POWER SHUT OFF:
The unit、vill automatically turn offifit is not operated for about 180 seconds or lnore.

l)In Case using battew
Take off batte竃 ァ cOVer left side ofIInaln body and insert 2 pieces of LR03 type batteries
to flt pol〔 rity indication.
4‐ 2 Measurement Procedures
l)Wrap the cuff around the left、vTist.
Facc up、 vards the palrn ofthe hand,Inake the body position in the center of the palm,
and、、 Tap the cuff tightly to the、 、嘲st,leaving no space between the cu∬ cloth.
In case you v′ear aヽvnst、vatch on your left、 、
‐st,please、、
Tap cuff after you put offit.
The position of the individual、vhen being IIneasured may be cither lying do、 、咀 or sitting.
In the sitting position ho、vever make sure that the location on the left、 vTist to be
measured is about at the same height as the heart and that the foreann is extended
naturally on the table and does not move.
Push the"START‖ s、、
itch to automatically inflate cuff to the optimun■ pressure.
Pressure start to descend. Please do not inove your body as possible as you can later.
Further descending cuff pressure,indication rnark for‖ Hcart mark‖
