4.Press the cuff to make sure that it is
attached securely. The cuff should not be too
tight or too loose. Two fingers should be
easily put in between cuff and upper arm.
5.The mark <INDEX> on the cuff must point to
area <NORMAL> or <LARGE CUFF>. This
means the cuff size is correct. If mark
<INDEX> points to the area beyond area
<NORMAL> or <LARGE CUFF>, please
consult your dealer whether you need another
size cuff.
6.Sometimes it is difficult to make the cuff
regular owning to the shape of the user's
upper arm, the cone-shape assembly of cuff
is also acceptable.
7.If your clothes restrict blood circulation of
your upper arm, or you roll your sleeve up so
as to result in such restriction. Please take off
your clothes to get accurate measurement if
necessary.
