AirSep Focus Patient Manual page 11

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.
When using Focus in an automobile, boat, or on other DC sources with the Universal AC/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.
When the automobile in which you are using the Focus unit is turned off, disconnect and remove the unit from the
automobile with you. Do not store Focus in a very hot automobile or in other similar, high-or low-temperature
environments. Operating or storing the unit outside the normal temperature range can affect the performance of the
Focus. (Refer to the Specifications section in this manual.)
If the Focus has been stored for an extended period of time outside its normal operating temperature range, the unit
should be allowed to return to normal operating temperature before being turned on. (Refer to the Specifications
section in this manual.)
Replace the disposable cannula as recommended by the manufacturer or your equipment provider. Additional supplies
are available from your Equipment Provider.
Do not position the Concentrator so that it is difficult to access the power cord.
The concentrator should be located as to avoid pollutants or fumes.
