9. ALARM INDICATORS
If the Zen-Olite™ Portable Oxygen Concentrator detects an alarm condition, it will indi-
cate 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 diff erently by the backlit display; yellow, and red LEDs; and buzzer, as
indicated below. In each case, the alarm message and power status will override the cur-
rent display.
IMPORTANT: All alarm conditions and parameters are factory preset; conditions and
parameters cannot be changed or adjusted by the user.
IMPORTANT: The alarm system is tested during the startup sequence. You should see
all alarm lights briefl y turn on and the audible alarm indicator chirp.
