This model [nubia Flip 3] mobile phone complies with the technical standards set by the government regarding the absorption of radio waves by the human body.
This mobile phone is designed to comply with the government's technical standards (*1) regarding human absorption of radio waves. These standards were established by the government while taking into consideration consistency with the radio wave protection limits established by the International Commission on Non-Ionizing Radiation Protection (ICNIRP), which is in collaboration with the World Health Organization (WHO), and the International Committee on Electromagnetic Safety (ICES) of the Institute of Electrical and Electronics Engineers (IEEE), and the limits include a sufficient safety margin regardless of the user's age or health condition.
The national technical standards stipulate the permissible values for radio wave protection in terms of the Specific Absorption Rate (SAR, for frequencies below 6 GHz), which indicates the average amount of radio wave energy absorbed by the human body, and the Power Density (PD, for frequencies above 6 GHz). The permissible SAR and PD values for mobile phones are 2.0 W/kg and 2 mW/cm2, respectively. Furthermore, the standards stipulate that when wireless functions that should be evaluated using each index are operating simultaneously, the total exposure ratio should be used. A total exposure ratio of 1 or less satisfies the permissible values.
The total exposure ratio for this mobile phone is a maximum of 1.984 (*2) at the side of the head and 1.980 (*2) when worn on the body (*3). Mobile phones are designed to have the minimum transmission power required for communication with mobile phone base stations, so the SAR and PD values are usually lower when actually making a call. These values may vary slightly depending on the individual product, but all meet the allowable values.
This mobile phone can be used in positions other than at the temple. Please use an accessory such as a carrying case to keep the phone at least 0 cm away from your body, and make sure there are no metal parts between the phone and your body. This has confirmed that this mobile phone complies with the national technical standards.
The World Health Organization has stated that "numerous studies have been conducted over the past 20 years to assess whether mobile phones pose a potential health risk. To date, no adverse health effects have been established as being caused by mobile phone use."

- *1 Technical standards are stipulated in the Radio Law-related Ministerial Ordinance (Article 14-2 of the Radio Equipment Regulations).
- *2 Includes/does not include wireless functions that can be used simultaneously with mobile phone service.
- *3 The values used to calculate the total exposure ratio for this mobile phone are: temporal: SAR 1.984W/kg, PD (absorbed power density) 0mW/cm2; when worn on the body: SAR 1.980W/kg, PD (absorbed power density) 0.255mW/cm2.
