Press the power button more than one second. 2. Bluetooth LED will turn to blue and blink, turning into standby pairing mode. 3. When running the air check application, you can ac- tivate the smartphone’s Bluetooth simply by following the instructions. 4. In the application settings menu, choose the available pairing device. Then, press the ‘pair’ button. It is paired up when the message ‘connected with the Air cube’ is displayed. 5. When it’s paired up, Bluetooth LED will turn to blue. When running the Air Cube application, you won’t need to pair up your Air Cube and the smartphone again if you have paired it up once before. (Bluetooth 4.0 or above / Coverage: maximum 11 meters) 89 [Charging] You can charge the device with a micro 5-pin smartphone charger or micro USB cable. The power LED will turn red while charging and it turns green when it is complete. If the battery LED flashes, it means that the battery has less than 10% power. Please charge the device immediately then. Smartphone Charger Micro USB cable 89 [Safety Instructions] ※ These safety precautions is to prevent any damage, malfunction or injuries. Failure to follow these instructions could result in fire, electric shock, injury or even death Do not place the Air Cube on an unstable surface. The product may be damaged if dropped. Do not disassemble, crush, puncture or shred the Air Cube. Please contact the service center when it needs to be repaired. (If you dis- assemble the product yourself, warranty will not apply.) Keep the Air Cube dry. Wipe the device with clean dry cloth. (Using oil washing detergent, paint thinner or wet wipes may cause exte- rior damages, electric shock, breakdown or even a fire.) Please ensure that no substances gets inside the product, such as drinks or water. Also, please avoid from flooding. (This may cause a breakdown or electric shock.) If the product is wet when charging, disconnect the product right away with caution. (This product is made for indoor use and is not water proof.) Do not use the Air Cube in a damp place. (This may cause a fire or electrical shock.) 1011 Please do not place the device in a vehicle under direct sunlight, on an electric blanket or on a rug. Also, avoid placing it in hot and humid environment such as sauna for a long time. (Panel disfigu- ration or it may cause malfunction.) Caution : Failure to follow these instructions may result in injury or product damage. Measurements are reliable data but it is for reference purposes. Therefore, the manufacturer and seller will not be held legally re- sponsible. Do not let the device be placed in a cold environment such as out- doors during winter or in a cold storage. It may not work properly. (Recommended operating environment: 0 ~ 45°C) Do not place the Air Cube close to objects with magnets or mag- netic components. This can cause damage or malfunction. Avoid dropping or knocking it down on hard surface. It may damage the board inside as well as increase the risk of injury by breakdown. Unplug charging accessories and store the device in a safe place when not being used for a long time. Do not connect the unit to other devices in a manner that is not described in the manual. 1011 [When Air Cube doesn’t work properly] Please refer to the following actions for different symptoms that may occur and also refer to the user manual enclosed before reporting a device failure. SymptomsAction Power is not turned on Make sure to press the power button more than one second. Check whether the battery is charged..

TEST METHODOLOGY Generally the tests were performed according to the KDB558074 v03r02. And ANSI C63.10-2013 was used to reference appropriate EUT setup and maximizing procedures of radiated spurious emission and AC line conducted emission testing. 4.1 EUT CONFIGURATION The EUT configuration for testing is installed on RF field strength measurement to meet the Commissions requirement and operating in a manner that intends to maximize its emission characteristics in a continuous normal application. 4.2 EUT EXERCISE The EUT was operated in the test mode to fix the TX frequency that was for the purpose of the measurements. According to its specifications, the EUT must comply with the requirements of the Section 15.207, 15.209 and 15.247 under the FCC Rules Part 15 Subpart C. 4.3 GENERAL TEST PROCEDURES Conducted Emissions According to the requirements in Section 6.2 of ANSI C63.10, the EUT is placed on the wooden table, which is 0.8 m above ground plane and the conducted emissions from the EUT are measured in the frequency range between 0.15 MHz and 30MHz using CISPR Quasi-peak and Average det…
