Open the medication cover and fill the medication cup with liquid medication.
Please see the Figure 4 Filling Procedure for reference.

Step Three:
Connect mask or mouthpiece as in Figure 5 below, and click ON/OFF switch to power on.

Please hold the nebulizer to keep liquid medication in contact with the vibrating mesh, and the stream of inhalation, Please see Figure 6 below.

Step Four:
When finishing nebulization, press ON/OFF switch to power off. Pour out the residual liquid medication from the medication cup. Please see Figure 7 below.

Step Five:
Clean after use:
Clean and disinfect the main unit, medication cover, medication cup and mask or mouthpiece by the method detailed in Section 7 (Please refer to the Section 7 Cleaning & Disinfection).
Note:
a.Please keep the device vertical and do not shake during the operation.
b.Holding inhaled breath for a short while can enhance the effectiveness of nebulization therapy.
c.The medication liquid will sometimes congeal on spray connector and mesh disc, which will influence the nebulization rate. We recommended stopping nebulization, removing mask or mouthpiece, and using clean medical gauze to clean the residue.
d. Please contact manufacturer with any additional questions for use.

Cleaning & Disinfection

Before and after use, be sure to clean and disinfect the main unit, medication cover, medication cup and mask or mouthpiece. We recommend one device be used and reused for a single person. The device is not provided sterile.
7.1 Cleaning
a. Remove the mask or mouthpiece from the main unit.
b. Pour a small amount of clean water into the medication cup and close the medication cover. Soak the medication cup for 5 minutes.
c.Turn on the device to nebulize the clean water for 1 to 2 minutes to remove residual medication from the mesh.
d.Turn off the device and disassemble the medication cover and medication cup from the main unit.
e. Please clean the casing of the main unit by moistening a clean medical gauze with clean water and immediately drying using clean medical gauze. Also clean the electrodes with clean medical gauze.

EMC Information
With the increased number of electronic devices such as PC’s and mobile (cellular) telephones, medical devices in use may be susceptible to electromagnetic interference from other devices. Electromagnetic interference may result in incorrect operation of the medical device and create a potentially unsafe situation.
Medical devices should also not interfere with other devices.
In order to regulate the requirements for EMC (Electro Magnetic Compatibility) with the aim to prevent unsafe product situations, the IEC60601-1-2 standard has been implemented. This standard defines the levels of immunity to electromagnetic interferences as well as maximum levels of electromagnetic emissions for medical devices.
Medical devices manufactured by Sunset Healthcare Solutions (Sunset) conform to this IEC60601-1-2 standard for both immunity and emissions.

Nevertheless, special precautions need to be observed:

1. NOTE The EMISSIONS characteristics of this equipment make it suitable for use in a residential environment (for which CISPR 11 class B is normally required).
2. WARNING: The use of accessories and cables other than those specified by Sunset, with the exception of cables sold by Sunset as replacement parts for internal components, may result in increased emission or decreased immunity of the device.
3. WARNING: The medical devices should not be used adjacent to or stacked with other equipment. In case adjacent or stacked use is necessary, the medical device should be observed to verify normal operation in the configuration in which it will be used.
4. WARNING: PORTABLE RF communications equipment (including peripherals such as antenna cables and external antennas) should be used no closer than 30cm (12 inches) to any part of [ME QUIPMENT or ME SYSTEM], including cables specified by the MANUFACTURER. Otherwise,degradation of the performance of this equipment could result.
5. WARNING: Do not use mobile (cellular) telephones and other devices(such as MRI,diathermy,electrocautery,RFID and electromagnetic security systems) which generate strong electrical or electromagnetic fields, near the medical device. This may result in incorrect operation of the unit and create a potentially unsafe situation. ecommendation is to keep a minimum distance of 7m. Verify correct operation of the device in case the distance is shorter.

Electromagnetic propagation is affected by absorption and reflection from structures, objects and people.

• 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 this device.
• Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
