2ARTZ-860AAction Camera

MAINTENANCE Underwater Usage Notes This camera are splash, water, and dust resistant and were tested under controlled laboratory conditions with a rating of IP68 under IEC standard 60529 (maximum depth of 10 meters up to 30 minutes). Splash, water, and dust resistance are not permanent conditions and resistance might decrease as a result of normal wear. In order to ensure the waterproof performance of the camera, please carefully refer to the operation and maintenance precautions as following. The machine is not waterproof due to improper operation and improper maintenance, which is not covered by the warranty. 1. Make sure to check whether the silicone pads on the waterproof cover is clean before using underwater. Otherwise it will affect the camera's waterproof ability, and a single hair or sand will cause leakage! 2. Make sure to check whether the silicone pad on the battery waterproof cover is intact,Damage to the silicone pad will cause water leakage! 3. Make sure that the battery waterproof cover is tightly closed before using underwater. If not,the camera will not be waterproof. 4. Avoid jumping into water a high speed with camera. Otherwise, the impact may result in water water leakage. 5. DO NOT use the camera in a hot spring or expose the product directly to high temperatures over 40°C. High temperature may cause deformation of the waterproof seal on the camera body and lose its waterproof function. 6. Keep it safe from falling and dropping. Falling and drop will cause damage to the watertight seal on the camera body and the camera is not waterproof. 7. The microphone and speaker's hole on the camera has built in waterproof material. DO NOT remove the waterproof material or poke the holes.Otherwise, the camera will no longer be waterproof. 8. Clean the camera with clean water after using underwater. Allow it to dry naturally before using again. 9. This camera is not waterproof unless the battery cover are closed. CAUTIONS  This is a 4K action camera, It is normal for the housing to exert heat under use.  Don’t expose the product directly to high temperatures over 45 °C.  Please properly protect well the lens and screen of camera after using.  Keep it safe from falling and dropping.  Keep it distance from any strong magnetic interference objects like electrical machine to avoid strong radio waves that might be damaging the product and affect the sound or image quality.  In case of overheating, unwanted smoke from the device, unplug it immediately from the power outlet to prevent hazardous fire.  Keep it safety from children while on charging.  Stored the device in a cool, dry and dust free location.  Do not modify the camera it in any way,if the camera has been detached,the warranty will be void. OVERVIEW OF CAMERA The camera is an all-weather action camera, equipped with 6-axis gyroscope EIS technology, which can take clear 20MP photos and capture stable videos at 4k/60fps. This camera adopting watertight seal and a hydrophobic coating on the camera body, which can reach IP68 waterproof level. This action camera is weatherproof and distinct to unlock all the filming scenarios and ease your vlogging experience.

FCC ID:2ARTZ-860A RF Exposure Evaluation According to KDB 447498 D01 General RF Exposure Guidance v06 and part 2.1093， Unless specifically required by the published RF exposure KDB procedures, standalone 1-g head or body and 10-g extremity SAR evaluation for general population exposure conditions, by measurement or numerical simulation, is not required when the corresponding SAR Test Exclusion Threshold condition(s), listed below, is (are) satisfied. For 100 MHz to 6 GHz and test separation distances ≤ 50 mm, the 1-g and 10-g SAR test exclusion thresholds are determined by the following: [(max. power of channel, including tune-up tolerance, mW) / (min. test separation distance, mm)] · [√f (GHz) ] ≤ 3.0 for 1-g SAR, and ≤ 7.5 for 10-g extremity SAR, where f (GHz) is the RF channel transmit frequency in GHz Power and distance are rounded to the nearest mW and mm before calculation The result is rounded to one decimal place for comparison Here, For 2.4G WIFI Mode Max Power(dBm) Max Power(mW) Frequency(MHz) Min. distance(mm) Calc. thresholds limit 802.11b 7.43 5.53 2462 5 1.74 3.0 802.11g 6.52 4.49 2462 5 1.41 3.0 802.11n20 5.33 3.41 2462 5 1.07 3.0 802.11n40 4.30 2.69 2452 5 0.84 3.0 For BT Mode Max Power(dBm) Max Power(mW) Frequency(MHz) Min. distance(mm) Calc. thresholds limit GFSK 3.074 2.03 2441 5 0.63 3.0 π/4-DQPSK 3.855 2.43 2441 5 0.76 3.0 8-DPSK 4.411 2.76 2441 5 0.86 3.0 Note: The 2.4G WIFI and BT are can not transmitting at the same time.
