IMPORTANT SAFEGUARDS
SAVE THESE INSTRUCTIONS
READ ALL INSTRUCTIONS BEFORE USING
WARNING –
1. THIS DEVICE IS NOT INTENDED FOR LIFE SUPPORT. It may stop operating due to power
interruption without hazard to patient.
2. If oxygen is used with the device, the oxygen flow must be turned off when the device is not in use.
Explanation of the Warning: When the device is not in operation and the oxygen flow is left on,
oxygen delivered into the tubing may accumulate within the device and create a risk of fire.
3. Oxygen is inflammable. Oxygen should not be used while smoking or in the presence of an open
flame.
4. Always ensure the device is generating airflow before the oxygen supply is turned on. Always turn
off the oxygen supply before stopping the airflow from the device.
5. This device should not be used in the vicinity of a flammable anaesthetic mixture in combination
with oxygen or air and nitrous oxide.
6. The airflow for breathing generated by this device may be as much as 7°C (12.6°F) higher than the
room temperature. This device should not be used if the room temperature is warmer than 35°C
(95°F) to prevent the airflow temperature from exceeding 40°C (104°F) and causing irritation to
your airway.
7. If this device overheats, it will stop operating and show message “Error 002” on the display. After
cooling down to the proper temperature, the device can be restarted.
8. This machine should be used only with masks (and connectors) recommended by the
manufacturer, or by your doctor or respiratory therapist. A mask should not be used unless the
CPAP machine is turned on and operating properly. The vent holes for the mask should never be
blocked, to allow for proper exhaling. If the vent hole is blocked, the CPAP machine will stop and
show message “Error 002”. After the machine cools down, please re-connect the power cord to
reset the machine.
9. At low CPAP pressure, some exhaled gas may remain in the mask and be breathed in again.
CAUTION –
1. Make sure the area around the machine is dry and clean. Dust and foreign particles may affect the
treatment. Keep the air inlet on the back of the machine clear to prevent overheating and damage
of the device. Do not place the machine near a source of hot or cold air. An extremely cold or hot
environment may damage the user's respiratory airway.
2. If there is a possibility of electro-magnetic interference with mobile phones, please increase the
distance between devices or turn off the mobile phone.
3. Do not connect the device to the personal computer for data downloading during the treatment.
This may cause a failure in the CPAP system.
4. To prevent from potential allergic reactions to mask used in the device, This machine shall be used
only with masks (and connectors) recommended by the manufacturer.

Recommended separation distances between portable and mobile RF
communications equipment and this device
This device is intended for use in an electromagnetic environment in which radiated RF disturbances
are controlled. The customer or the user of this device can help prevent electromagnetic interference
by maintaining a minimum distance between portable and mobile RF communications equipment (transmitters) and
this device as recommended below, according to the maximum output power of the communications equipment

For transmitters rated at a maximum output power not listed above, the recommended separation distance d in meters
(m) can be estimated using the equation applicable to the frequency of the transmitter, where P is the maximum output
power rating of the transmitter in watts (W) according to the transmitter manufacturer.
Note 1: At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
Note 2: These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and
reflection from structures, objects, and people.

b) The compliance levels in the ISM frequency bands between 150 kHz and 80 MHz and in the frequency range 80
MHz to 2,5 GHz are intended to decrease the likelihood that mobile/portable communications equipment could
cause interference if it is inadvertently brought into patient areas. For this reason, an additional factor of 10/3 is
used in calculating the recommended separation distance for transmitters in these frequency ranges.
c
) Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land
mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically with
accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey
should be considered. If the measured field strength in the location in which the device is used exceeds the
applicable RF compliance level above, the device should be observed to verify normal operation. If abnormal
performance is observed, additional measures may be necessary, such as reorienting or relocating the device.

1. Introduction
This manual should be used for initial set up of the system and saved for reference purpose.
1.1 General Information
Obstructive Sleep Apnea (OSA) is a condition that an intermitted and repetitive obstruction of the
upper respiratory tract causes a complete (apnea) or partial (hypopnea) block of breathing airflow
during sleep. The syndrome varies depending on the degree of relaxation of the tongue and soft
palate.
The most common treatment for OSA is Continuous Positive Airway Pressure (CPAP). CPAP
devices can deliver a constant air pressure into your upper airway via a nasal mask. This constant
air pressure can keep your airway open during sleep, therefore prevents the OSA.
This device is a micro-processor controlled continuous positive airway pressure device. It features
the illuminated, menu-driven LCD display, universal power supply and ramp time adjustment. The
ramp time adjustment and ultra quiet operation ensure you to fall asleep comfortably while air
pressure slowly builds up to treatment level. The user compliance meter records the total
system’s operating time for physician’s reference.
The system has been tested and successfully approved to the following standards:
IEC/EN 60601-1
