3.0 Operating Instructions
3.1 General Instructions
It is important that patients thoroughly understand how to operate AirSep’s Focus unit.
 This enables proper treatment as prescribed by a qualified, licensed physician. You must explain 
 that the purpose of this therapy is to alleviate symptoms. If patients experience any discomfort or if 
 the unit alarms, they must notify their Equipment Provider
and/or
physician immediately.
 You, as the Equipment Provider, are responsible to ensure that each patient receives the Focus 
Patient Manual. Explain each step in the operation of the unit to the patient with reference to the patient 
manual. 
Instruct patients that AirSep recommends that Focus should be used while sleeping only under the 
direction of their clinician. In addition, some patients who tend to be mouth-breathers may benefit from 
the use of a chin strap. 
3.1.1 Connecting to Focus’s Power Inlet
Locate the arrow marking at the top of the connector. Insert connector (Figure 1) into the Focus 
power inlet (Figure 2) with the arrow on the side of the connector facing outward. Do not force 
the connector into the power inlet, as it can be inserted only one way. This ensures that neither 
the unit nor the power accessories are damaged. 
Turn the Focus unit on by pressing the power switch to the on position (l).

NOTE: Always connect to the Focus power inlet first before connecting to a power 
supply. 
1) Connecting Focus to AC electrical power
When you are near an AC outlet, you may choose to operate Focus with the universal power 
supply rather than the battery.Connect the cord on the power supply labeled as DC OUT To 
Focus into the Focus unit’s power inlet,as shown in Figure 3. Do not force the plug, as it should 
be inserted only one way. Plug the 3-prong AC cord from the power supply into any standard 
outlet. 
Turn the Focus unit on by pressing the power switch to the on position (
