This device may only be used for the purposes described in these instructions. The manufacturer cannot be held liable for damage caused by incorrect application.
Prior to using the device for the first time, we recommend cleaning it as described in the section «Cleaning and Disinfecting»
Do not use this device if you think it is damaged or notice anything unusual.
Never open this device.
This device comprises sensitive components and must be treated with caution. Observe the storage and operating conditions described in the «Technical Specifications» section.
Protect it from
– water and moisture

The function of this device may be compromised when used close to strong electromagnetic fields such as mobile phones or radio installations and we recommend a distance of at least 1 m (according to 60601-1-2 table 5).
In cases where you suspect this to be unavoidable, please verify if the device is working properly before use. If the device is not going to be used for a prolonged period the batteries should be removed.
**** Ensure that children do not use this device unsupervised; some parts are small enough to be swallowed. Be aware of the risk of strangulation in case this device is supplied with cables or tubes.
This device is not a toy! Keep out of reach of children and do not leave children alone during treatment.

Directions for Use

Choose the suitable silicone tip 6 based on the size of the patient’s nostrils.
Be sure to place the silicone tip 6 securely on the mucus cup.
Gently insert the silicone tip into the patient’s nostril. Do not insert it too deeply.
Press the ON/OFF button 1 for a few seconds to collect mucus. Stop pressing the ON/OFF button when finished using the device and then the power will be stopped.
**** If the accumulated volume of mucus is nearly over the safe capacity of the mucus cup 2 (about 4 ml), follow the section of «5. Cleaning and Disinfecting» to clean the device first.
Do not use the device if the mucus level is nearly over the opening channel (where the arrow points to on the right 13 a).

Inserting the batteries

After you have unpacked your device, first insert the batteries. Remove the battery cover by separating the upper cover 4 away from the lower cover 5 in a straight direction. Do not bend the covers by brute force as it can be slid open easily. Insert the batteries (2 x 1.5 V, size AA), thereby observing the indicated polarity. Check to make sure that the two silicone rings 7 are properly seated on the grooves. Close the covers until the “click” sound is heard.
**** Replace the batteries when the suction power becomes m weak during use.
Always replace both batteries at the same time.

Cleaning and Disinfecting

Be sure that the upper 4 and lower 5 covers are closed firmly before cleaning the device AT-a.
Remove the silicone tip AT-b.
Hold the mucus cup 2 with the part between the thumb and index finger AT-c.
Bend the mucus cup 2 downwards gently to remove it from the collar AT-d.
Remove the silicone rings 7 from the collar 3 for cleaning after several uses of the device AT-e. The silicone rings do not need to be cleaned every time.
Wash the parts thoroughly with clean water and soap AK-a. Rinse the collar 3 under the tap AK-b. Dry the parts before assembling them.
Reassemble all parts AL. Properly align the positioning hole on the mucus cup AL-b.
Be sure that all parts fit tightly together on the device.

When the accumulated volume of mucus is over the safe capacity of the mucus cup during use of the device, if you see mucus dripping out of the air vent on the back side of the collar AM-a, please follow the instructions below:

Be sure that the upper 4 and lower 5 covers are closed firmly AM-b.
Remove the silicone tip 6 and mucus cup 2.
Have the collar 3 immersed in clean water? Press the ON/OFF button 1 for 15 seconds and the inner pump will be cleaned AM-c.
The water flows in and out of the inner pump in the direction as shown AM-d.
Remove the device from water once the cleaning is completed. Keep pressing the ON/OFF button 1 for approximately 30 seconds until the inner pump is dried.
Dry the collar 3 and reassemble the parts AL.

Guidance and manufacturer’s declaration

Electromagnetic immunity
The BC 50 is intended for use in the electromagnetic environment specified below. The customer or the user of the BC 50 should assure that it is used in such an environment.

Emissions	Compliance	Electromagnetic environment – guidance
RF emissions CISPR 11	Group 1	The BC 50 uses RF energy only for its internal

function. Therefore, its RF emissions are very low and are not likely to cause any interference in nearby electronic equipment.
RF emissions CISPR 11| Class B| The BC 50 is suitable for use in all establishments, including domestic establishments and those directly connected to the public low-voltage power supply network that supplies buildings used for domestic purposes.

The power frequency magnetic field should be measured in the intended installation location to assure that it is sufficiently low.

Electromagnetic immunity
The BC 50 is intended for use in the electromagnetic environment specified below. The customer or the user of the BC 50 should assure that it is used in such an environment.

---|---|---|---
Conducted RF IEC 61000-4-6| 3 Vrms
150 kHz to 80 MHz| Not applicable| Portable and mobile RF communications equipment should be used no closer to any part of the BC 50, including cables, than the recommended separation distance calculated from the equation applicable to the frequency of the transmitter.
Radiated RF IEC 61000-4-3| 3 V/m

d=2.3,/P 800 MHz to 2.5 GHz
where P is the maximum output power rating of the transmitter in watts (VV) according to the transmitter manufacturer and d is the recommended separation distance in meters (m).
Field strengths from fixed RF transmitters, as determined by an electromagnetic site survey,, should be less than the compliance level in each frequency range Interference may occur in the vicinity of equipment marked with the following symbol:
NOTE 1 At 80 MHz and 800 MHz, 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.
a. Field strengths from fixed transmitters, such as base stations for radio (cellular/ cordless) telephones and land mobile radios, amateur radio, AM and FM radio broadcasts, and TV broadcasts 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 BC 50 is used exceeds the applicable RF compliance level above, the BC 50 should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as re-orienting or relocating the BC 50.
