CONTROLS AND POWER UP
THE FRONT PANEL
Located above and to the right of the ventilator outlet, is the rotational Control
Knob, which allows control of and access to all the ventilator functions via the
LCD screen. Turn the knob to change a value, or navigate through a menu screen
or through a list of choices. Press the knob and the iVent
TM
201 responds with a
tactile click and with audible feedback – to select or confirm a choice, or to
access another menu.
Where a numeric value is required, selection is done by rotating the dial to move
a virtual slider bar, spin button, or counter, in increments calibrated precisely
along the full range of values. In some settings menus, one press of the knob is
enough to instantly select or confirm a value, which thereafter immediately
returns you to the previous screen.
Five dedicated keys are positioned below the LCD (Figure 24):

Silence
Silence is used to immediately mute the audible alarm and minimize the
corresponding red message pop-up window. A two-minute timer is activated and
displayed in the lower right corner of the display instead of the time-date field,
alongside the silenced alarm icon (Figure 25).
One short press on the Silence key resets the time to 2 minutes. Press the Silence
key for one second and it re-activates pending alarms.
