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.
In addition, when the unit is operating and the battery is simultaneously being
charged through the AC or 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 remain on for approximately one hour 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 the specifications. The light
and audible alarm conditions are explained in detail below and summarised 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 (lights)
stop and green LEDs (lights) remain on.
•
Low Battery
Focus unit indicators: As the battery power approaches a low level,
the amber light on the Focus unit will flash on for half a second with a
5-second pause and simultaneously, a half 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
simultaneously, a half second alarm sounds 2 times with a 5 second
pause.
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
socket or to an AC power socket, 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.
