Using Quha Sento for Zono X
Place the puff switch on your head and
adjust the headband so that it fits firmly
and comfortably over your head. The
magnetic holder is worn on the right side
of the head with the flat end of the
holder pointing directly forward.
The puff switch detects the air flow
(puff) coming from the user
’
s mouth.
The puff sensor is located at the end of
the sensor arm. The more air flow there
is to the sensor, the more accurately the
switch can be controlled. Therefore, it is
necessary to place the sensor to a
position that the air flow can reach.
The flexible sensor arm should be adjusted so that the sensor is
located in front of the user
’
s mouth at a comfortable distance. A
typical distance is 1
-
5 cm (½
-
2 inch). The user is suggested to
try different positions because the air flow strength varies
greatly. With some experimenting, a good position is found in a
few minutes.
Testing the switch is simple. Puff into the sensor and a left click
is performed. Puff and keep puffing into the sensor and a long
click (dragging) is performed as long as the puff continues.
