Alarm Indicators
If the Portable Oxygen Concentrator detects an alarm condition, it will indicate the alarm visually and audibly within 10 seconds. There are four levels of alarms: critical high priority, high priority, medium priority, and low priority. Each is indicated differently by the backlit display; green, yellow, and red LEDs; and buzzer, as indicated below. In each case, the alarm message and power status will override the current display.
Note: All alarm conditions and parameters are factory preset; conditions and parameters cannot be changed or adjusted by the user.
| Alarm Status | Audible Tone | Visual Indicator | Mute Time |
| Critical high | Ten beeps per burst, burst | Solid red LED | 20 minutes |
| priority | repeats every 3 seconds | (and device shuts |
|
|
|
| off automatically) |

Note: If two alarm conditions exist at the same time, the highest priority alarm is indicated. If two or more alarm conditions of equal priority exist at the same time, the most recent one will be displayed.
Note: The most recent alarms indicated by the device are logged for reference by service personnel. This log is maintained even if the device is powered down or if power is lost for any other reason.
Note: If the mute key is pressed prior to an alarm condition (for example, to mute the device in a movie theater), critical high priority and high priority alarms will override the mute function; medium and low priority alarms will be muted for eight hours from the time the key was pressed. Press the mute key off to display the last highest priority alarm. Press the mute key on again to reset the eight- hour timer.
