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
control panel blinks each time a breath is detected.
Additionally, when the unit is operating and the battery is simultaneously being charged through the Universal AC / DC power
supply, the battery for the Focus unit will display the charge level of the battery (25% to 100% state of charge) on the battery
gauge/indicator(s) and when at 100%, LEDs (lights) remain on for approximately 15 minutes after reaching a full charge.
An audible alarm sounds if Focus has a low battery, if the cannula is disconnected, or if performance of the unit is outside of
specifications. The light and audible alarm conditions are explained in detail below and summarized on the chart later in this
section of the manual.
• Start-Up
A brief alarm sounds and the green and red LEDs (lights) will alternate at start-up. Focus begins to operate when the
alternating LEDs (light) stop and green LED (lights) remains on.
• Low Battery
ê Focus unit indicators: As the battery power approaches a low level, the amber light on the Focus unit will flash on for
½ second with a 5-second pause and simultaneously, a ½ second alarm sounds with a 5-second pause. Following the
battery warning indicators, if action is not taken, the unit will shut down. This will be indicated when the amber light
flashes 2 times with a 5-second pause and simultaneously, a ½ second alarm sounds 2 times with a 5 second pause.
ê Battery indicator: The green light indicator on the battery gauge (Figure 9) light illuminates intermittently.
When either of these conditions occurs, connect Focus to a DC power outlet or to an AC power outlet, or change to
another source of oxygen within two minutes. The level of battery charge is indicated by the battery gauge/indicator(s).
You can also check the state of charge at any time by pressing the button.
As noted above, when the unit is connected to AC or DC power outlet, you may simultaneously charge the Focus battery
supplied with the unit while using the unit.
In the event of an alarm or you observe Focus is not working properly; consult the Troubleshooting section in this
manual. If you cannot resolve the problem, consult your Equipment Provider.
