•
The blue LED located to the upper-right of the VENTILATION ON/OFF key ( Figure 5-4 ,

5.4 Turning Off the Ventilator
Set the I/O switch to the O position to power off the ventilator.
•
The blue LED to the right of the VENTILATION ON/OFF key turns off.
•
The ventilator screen switches off.
WARNING
•
When ventilation is in progress: if the ventilator is stopped using the I/O switch without previously
stopping the ventilation, a continuous audible alarm is activated.
•
When the ventilator is switched back on, it will immediately begin ventilating—without the user first
having to press the VENTILATION ON/OFF
key.
Note:
When the ventilator is completely stopped, but is still connected to the AC power source (the green
AC POWER indicator is illuminated), the internal battery continues charging.
WARNING
Handle the ventilator with care after use, particularly when room temperatures are high. Some ventilator
surfaces may be very hot, even if safety specifications are not exceeded.
