Audible Alarm and Indicator Lights

When the Focus unit senses inhalation, a pulse of oxygen is delivered through the nasal cannula. The green light on the unit's

Additionally, when the unit is ope rating and the battery is simultaneously being charged through the AC or DC power s upply,
the battery for the Focus unit will displa
gauge/indicator(s) and remain on for approximately one hour after reaching a full charge.
An audible alarm sounds if Focus has a low battery, if the cannul a is disconnected, or if perfor mance of the unit is outside of
specifications. The light and audi ble alarm conditions are explaine d in detail below and summ arized on the chart later in this
