switch, one of the indicator lights is lit. Green light indicates the
battery condition is good for use, red light indicates the battery

Vento can be used as a switch for various purposes such as
environment control, nurse calls and computer mouse clicks.
Using Quha Vento
Quha Vento 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 position
the sensor so that the air flow can reach it.
The flexible sensor arm is 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 (0.4-2 inch). Try different positions to find the
one most suitable for you. Because the air flow strength varies
greatly between users, it is possible to find a good position with
some experimenting in a few minutes.
Testing the switch is simple. Puff into the sensor and the switch
is activated. Puff and keep puffing into the sensor and the switch
remains active as long as the puff continues.
Compatibility
Quha Vento is compatible with devices with a 3.5 mm switch
connector.
