Detailed instructions can also be found in the device in the form of electronic files. Please read the Manual stored in the device. The contents of the Manual are based on the status of the device upon the time of manufacture. Certain functions depend on the local situation and service providers. Please use the device according to the actual local situations. This device and associated software and accessories may vary from region to region. Please consult your local vivo dealer for more details. Do not use while you are driving For body-worn operation maintain a separation of 5mm This device is not intended for use by young children. If you allow a child to use it ensure the child is strictly supervised. This device contains small parts which are a choking hazard Read this Product Safety Information before using this device. Failure to comply with safety warnings can result in serious injury. This device may produce a loud sound 2 Switch off when instructed in hospitals and medical facilities Switch off when instructed in aircrafts and airports Switch off in explosive environments Do not use this device whilst walking across a road or cycling Keep away from pacemakers and other personal medical devices Do not use while refuelling or near gas or flammable liquids This device may produce a bright or flashing light Do not dispose of this device or its battery in a fire. 3 Avoid contact with magnetic media Avoid Extreme Temperatures Avoid contact with liquid, keep dry Do not try and disassemble Do not rely on this device for emergency communications Only use approved accessories 4 RF Exposure Your phone contains a radio transmitter and a receiver. When it is ON, it receives and transmits RF energy. When you communicate with your phone, the system handling your call controls the power level at which your phone transmits. -Specific Absorption Rate (SAR) Your mobile device is a radio transmitter and receiver. It is designed not to exceed the limits for exposure to radio waves recommended by international guidelines. These guidelines were developed by the independent scientific organisation ICNIRP and include safety margins designed to assure the protection of all persons, regardless of age and health. The guidelines use a unit of measurement known as the Specific Absorption Rate, or SAR. The SAR limit for mobile devices is 2 W/kg. Please refer to the Quick Start Guide or visit vivo's official website for the actual SAR value of the product. SAR is measured utilising the device’s highest transmitting power and where supported with multiple simultaneous transmitters. The actual SAR of this device while operating is typically well below that indicated above. This is due to automatic changes to the power level of the device to ensure it only uses the minimum power required to communicate with the network. *The tests are carried out in accordance with [CENELEC EN50360] [IEC 62209-1] -Body worn operation To ensure compliance with RF exposure guidelines the phone must be used with a minimum of 0.5 cm separation from the body. 5 Failure to observe these instructions could result in your RF exposure exceeding the relevant guideline limits and may use more power than necessary. -Limiting exposure to radio frequency (RF) fields For individuals concerned about limiting their exposure to RF fields, the World Health Organisation (WHO) provides the following advice in Fact Sheet 193 Electromagnetic fields and public health: mobile phones (October 2014): Precautionary measures: Present scientific information does not indicate the need for any special precautions for the use of mobile phones. If individuals are concerned, they might choose to limit their own or their children’s RF exposure by limiting the length of calls, or using ‘hands-free’ devices to keep mobile phones away from the head and body. Further information on exposure to radio waves can be obtained from the WHO http://www.who.int/mediacentre/factsheets/fs193/en/ >>Precautions for use of the device (for France) Measures affecting the safety of users and non-users *Do not use mobile phones in certain situations (while driving) and places (planes, hospitals, schools, gas stations and professional garages). *Precautions to be taken by wearers of electronic implants (pacemakers, insulin pumps, neurostimulators, etc.), particularly with regard to the distance between the mobile phone and the implant (15 centimeters) and the position of the phone - when making a call, put the phone on the side opposite the implant. Advice for use to reduce the consumer's level of exposure to radiation (it should be noted that this advice is given purely as a precautionary measure, as no danger associated with the use of a mobile phone has been identified) 6 *It is recommended to use mobile phones in good reception conditions to reduce the amount of radiation received (especially in an underground car park, when travelling by train or car...). *Indication of good signal reception (e.g. four or five bars displayed on the phone screen). *It is recommended to use a hands-free kit and, in this situation, precautions should be taken during a call: keep the phone away from the stomach for pregnant women or the lower abdomen for adolescents. *Use a hands-free kit or speakerphone, if suitable for radio equipment. *Make sensible use of radio equipment such as mobile phones when used by children and adolescents, for example by avoiding night- time calls and limiting the frequency and duration of calls.<< -Regulatory information The following safety approvals and notices apply in specific regions as noted.
