Frequently Asked Questions  
How will it feel when I am breathing with the S8 Series II?  
When you first use your S8 Series II device, you may feel uncomfortable breathing  
against the airflow. This is normal. You will continue to breathe normally while you  
sleep. The EPR setting may also improve comfort. Take time to adjust to this new  
sensation.  
What do I do when I want to get up in the night?  
If you need to get up during the night, remove your mask and stop therapy. Always  
remember to restart therapy and put your mask on when you return to bed.  
What do I do if I feel air leaking out of the mask?  
The S8 Series II delivers the most effective treatment when the mask is well fitted and  
comfortable. Treatment can be affected by leaks, so it is important to eliminate any  
leaks that may arise. For example, try repositioning the mask and adjusting the straps.  
If you are using a nasal mask, try to keep your mouth closed during treatment. Air leaks  
from your mouth can decrease the effectiveness of your treatment. If mouth leaks are  
a problem, a full face mask or chin strap may help. Contact your clinician or equipment  
supplier for further details.  
If you are using a full face mask and you have problems trying to get a comfortable  
mask fit, contact your clinician or equipment supplier. You may benefit from a different  
size or style of mask.  
Anything special I should do before putting the mask on?  
Before wearing your mask, wash your face to remove excess facial oils. This will allow  
a better fit and prolong the life of the mask cushion.  
Do not use moisturiser when wearing a mask.  
My mouth feels dry during treatment—what can I do?  
You may experience dryness of the nose, mouth, and/or throat during the course of  
treatment, especially during winter. In many cases, a humidifier may resolve this  
discomfort. Contact your clinician for advice.  
My nose is irritated during treatment—what can I do?  
You may experience sneezing and/or a runny or blocked nose during the first few  
weeks of treatment. In many cases, nasal irritation can be resolved with a humidifier.  
Consult your clinician or equipment supplier for advice.  
Can I travel with the S8 Series II?  
Your S8 Series II has an internal power supply that enables it to operate in other  
countries. It will operate on power supplies of 100–240V and 50/60Hz. No special  
adjustment is necessary, but you will require an approved power cord for the region in  
which you are using the device.  
Your S8 Series II device automatically adjusts to changes in altitude up to 2,591 m.  
Frequently Asked Questions

S8 Series II on an aircraft. The S8 Series II complies with US FCC Part 15, Class B  
requirements.  
Note: Do not use your S8 Series II while the aircraft is taking off or landing.  
Can I use my S8 Series II if mains (AC) power is not available?  
A DC-12 converter is available to connect the S8 Series II to a 12V or 24V DC power  
source. Contact your clinician for details.

Environmental information WEEE 2002/96/EC is a European Directive  
that requires the proper disposal of electrical and electronic equipment. This device should be  
disposed of separately, not as unsorted municipal waste. To dispose of your device, you should  
use appropriate collection, reuse and recycling systems available in your region. The use of these  
collection, reuse and recycling systems is designed to reduce pressure on natural resources and  
prevent hazardous substances from damaging the environment. If you need information on these  
disposal systems, please contact your local waste administration. The crossed-bin symbol invites  
you to use these disposal systems. If you require information on collection and disposal of your

General Warnings and Cautions  
WARNINGS  
!
Read the entire guide before using the S8 Series II.  
Advice contained in this guide should not supersede instructions given by the  
prescribing physician.  
A patient should not connect a device to the data communication port unless  
instructed to do so by their health care provider or physician. Only ResMed  
products are designed to be connected to the data communication port.  
Connecting other devices could result in injury, or damage to the S8 Series II  
device.  
The S8 Series II should be used with masks (and connectors)* recommended  
by ResMed, or by a physician or respiratory therapist. A mask should not be  
used unless the S8 Series II device is turned on and operating properly. The  
vent hole or holes associated with the mask should never be blocked.  
Explanation: The S8 Series II is intended to be used with special masks (or  
*
connectors) which have vent holes to allow continuous flow of air out of the  
mask. When the device is turned on and functioning properly, new air from  
the device flushes the exhaled air out through the mask vent holes. However,  
when the device is not operating, insufficient fresh air will be provided  
through the mask, and the exhaled air may be rebreathed. Rebreathing of  
exhaled air for longer than several minutes can, in some circumstances, lead  
to suffocation. This applies to most models of PAP devices.  
In the event of power failure or machine malfunction, remove the mask.  
The S8 Series II can be set to deliver pressures up to 20 cm H O. In the  
2
unlikely event of certain fault conditions, pressures up to 30 cm H O are  
2
possible.  
*
Ports may be incorporated into the mask or in connectors that are near the mask.  
General Warnings and Cautions

If oxygen is used with this device, the oxygen flow must be turned off when  
the device is not operating.  
If the oxygen has been left on, turn off the device, then wait 30 minutes  
before turning on the device again.  
Explanation: When the PAP device is not in operation and the oxygen flow is  
left on, oxygen delivered into the air delivery tubing may accumulate within  
the PAP machine enclosure and create a risk of fire. This applies to most  
types of PAP machines.  
Oxygen supports combustion. Oxygen should not be used while you are  
smoking or in the presence of an open flame.  
Always ensure airflow is being generated by the device before the oxygen  
supply is turned on.  
Always turn the oxygen supply off before stopping the airflow from the  
device.  
Note: At a fixed rate of supplemental oxygen flow, the inhaled oxygen  
concentration will vary, depending on where the oxygen is introduced, the  
pressure settings, patient breathing pattern, mask selection, and leak rate.  
Do not use the S8 Series II if there are obvious external defects or  
unexplained changes in performance.  
Do not open the S8 Series II case. There are no user serviceable parts inside.  
Repairs and internal servicing should only be performed by an authorised  
service agent.  
Explosion hazard—do not use in the vicinity of flammable anesthetics.  
CAUTIONS  
!
At low pressures, the flow through the exhalation ports of your mask may not  
clear all exhaled gas from the tubing. Some rebreathing may occur.  
The airflow for breathing produced by this device can be as much as 11ºF  
(6ºC) higher than the temperature of the room. Caution should be exercised if  
the room temperature is warmer than 90ºF (32ºC).  
When AC mains power (100–240V AC) is not available, always use a ResMed  
DC-12 converter. (The DC-12 converter is available as an optional accessory. It  
is not supplied with all models.)  
Note: The above are general warnings and cautions. Specific warnings,  
cautions, and notes appear with the relevant instructions in the manual.
