About the Aranet4 device

The Aranet4 sensor is a battery powered CO² meter with additional measurements of

temperature, relative humidity and atmospheric pressure. * The device is suitable for

monitoring the CO² level at home, in school, office or any other indoor environment.

Measurement data is displayed on a power-efficient e-ink screen allowing for long battery life.

Additionally the device can provide visual and sound notifications in case of the CO²

concentration becomes unhealthy. The high concentration level of 1400 ppm (parts per

million) – level typically associated with complaints of drowsiness and poor air quality.

Data transmission interval: 1, 2, 5 or 10 minutes.

Default measurement interval is set to 5 minutes.

Aranet4 uses the nondispersive infrared (NDIR) sensor to measure the concentration of CO².

The CO² gas in the chamber absorbs infrared light and this absorption is measured by the

sensor. The less light passes through – the higher the CO² concentration. The CO² gas absorbs

only a specific wavelength of the light therefore an optical filter is used.

By using the Aranet4 app on your smart device it is possible to wirelessly access real-time

data and up to one week of historical measurement data. The app also allows you to

configure the Aranet4 device. The Aranet4 app supports connection of several Aranet4

sensors to monitor their parameters remotely from a single smart device.

Additionally up to 100 Aranet4 PRO devices can be connected to the Aranet PRO base station.

Refer to the chapter Using Aranet4 device with the Aranet PRO base station.

* Atmospheric pressure data measurements are available only on the Aranet4 app.

CO² calibration

The Aranet4 device is calibrated at the factory. However, the user can perform CO²

calibration manually when needed. During the manual calibration the Aranet4 device

must be exposed to fresh air (about 420 ppm of CO²) and the environment should be

stable (not changing). Maintain a distance of at least 1 meter from the device during

the calibration process.

To start the manual CO² calibration, change the position of the switch (see next

chapter Switch positions explained) from MANUAL to AUTO and then back to

MANUAL (maintain maximum of 1 second between each movement).

The calibration progress will be displayed on the screen of the device. In case of a

calibration failure message, make sure that the environment requirements are met

and repeat the process from the beginning.

Manual calibration can be done using the Aranet4 app as well.

In case of automatic calibration mode, the Aranet4 device needs to be exposed to a

fresh air at around 420 ppm (for instance, outdoors or room with good air exchange)

at least 8 hours each month.

SAF Tehnika AS 24a, Ganibu dambis, Riga Latvia LV-1005 FCC ID: W9Z-A4MK2HOME FCC Rules: 15.247 Digital Transmission System Dear Sirs:

SAF Tehnika AS requests that the material in the Schematics, Block Diagram, Operational Descriptions, and Tune Up Procedure be withheld from public disclosure pursuant to Sections 0.457 and 0.459 of the Commissions Rules following grant of the application. In support of this request, SAF Tehnika AS submits the following:

Long Term Confidential Files Include File Exhibit A4MK2HOME Conf Schem.pdf Schematics A4MK2HOME Conf BlkDia.pdf Block Diagram Operational Description A4MK2HOME Conf OpDes.pdf Tune Up Procedure A4MK2HOME Conf TunPro.pdf 1. Identification of the specific information for which confidential treatment is sought:

The materials set forth in the Schematics, Block Diagram, Operational Descriptions, and Tune Up Procedure, which are segregated from the non-confidential exhibits of the application, are those for which confidentiality is sought. 2. Identification of the Commission proceeding in which the information was submitted or a description of the circumstances giving rise to the submission:

The proceeding is that involving the application for equipment authorization (certification) under FCC ID: W9Z-A4MK2HOME File: A4MK2HOME Conf Request Letter Page 1 of 2 3. Explanation of the degree to which the information is commercial or financial, or contains a trade secret or is privileged:

This material includes a detailed theory of operation, circuit diagrams, (schematic diagrams) and any detail Parts List. As such, this material is treated as highly confidential business information. 4. Explanation of the degree to which the information concerns a service that is subject to competition:

The material for which confidentiality is sought is employed in the design and manufacture of this transmitting equipment that is offered on a highly competitive basis. Customers for this equipment have a variety of competing sources. 5. Explanation of how disclosure of the information could result in substantial competitive harm:

Disclosure would, in effect, give away the fruits of the labors of SAF Tehnika AS engineering personnel, who have designed the equipment and the manufacturing process. Disclosure would also offer competitors additional unwarranted insight into the state of the product development, thereby allowing competitors an advantage, not available to SAF Tehnika AS. 6. Identification of any measures taken by the submitting party to prevent unauthorized disclosure:

The information for which confidential treatment is sought is kept confidential by SAF Tehnika AS and not made available to third parties except pursuant to non-disclosure agreements. 7. Identification of whether the information is available to the public and the extent of any previous disclosure of the information to third parties:

To the knowledge of those preparing this application, the information has not been disclosed publicly heretofore. While the general theory of operation of this equipment has been the subject of numerous disclosures in industry and standards groups as well as in rule making proceedings of the FCC, the protection sought is narrowly drawn and pertains to certain specific implementations of this radio technology. 8. Justification of the period during which the submitting party asserts that the material should not be available for public disclosure:

This material should not be disclosed for at least 25 years. While improvements in design are made relatively frequently, disclosure of the design information would lead to insights into both design and manufacturing techniques that could have an adverse competitive effect for many years to come. As such, it is important that the design not be made available to unauthorized persons who might attempt to use knowledge of the design to compromise the applications for which the equipment will be employed. Should you require any further information, please contact the undersigned. Thank you for your consideration in this matter.
