AirSep Focus Portable Patient Manual page 9

Care should be taken to prevent Focus from getting wet or allowing water to enter the unit. This can cause the unit to
malfunction or shut down.
Federal (USA) law restricts this device to sale or rental by order of a physician or other licensed health care provider.
In the event of an alarm or you observe that Focus is not working properly; consult the Troubleshooting section in this
manual. If you cannot resolve the problem, consult your Equipment Provider.
The Focus Portable Oxygen Concentrator may be used during sleep under the recommendation of a qualified clinician.
Operating the Focus unit outside of its normal operating temperature range can affect performance and decrease
battery run time and/or increase battery charge time. (Refer to the Specifications section in this manual.)
Do not allow either the air intake or the air outlet vents to become blocked. This can cause the Focus unit to overheat
and affect performance.
Do not operate unit in a restricted or confined space (i.e., a small case or handbag) where ventilation can be limited.
This can cause the Focus unit to overheat and affect performance.
Storing the Focus unit outside of its temperature specifications may affect performance. (Refer to the Specifications
section of this manual)
When using Focus in an automobile, boat, or on other DC sources with the DC power supply, make sure that the vehicle
is started and running before connecting the Focus unit. If the DC power supply does not illuminate and requires resetting,
disconnect the DC power supply from the DC outlet, restart your vehicle, and then reconnect your DC power supply into
the DC outlet. Failure to follow these instructions can result in the power supply not supplying power to Focus.
