For your safety

Don’t use a hand-held phone while driving.

Stop and park your vehicle safely before using your phone.

Switch off in aircraft

Wireless devices can cause interference in aircraft. The use of mobile telephones in an aircraft is illegal. Please switch off your mobile before taking off the plane and please ensure the alarm clock should be closed when the mobile is turned off.

Switch off near blasting

To avoid interference in the process of blasting, don’t use the phone where you may read the sign of “Blasting Spot” or “Turn off your wireless”. Observe restrictions and follow any regulations or rules.

Switch off near dangerous stuff.

Don’t use the phone at a refueling point. Don’t use near fuels or chemicals.

Switch the phone off in hospitals.

Switch the phone off near medical equipment. There may be a hazard associated with the operation of phones close to inadequately protected personal medical devices such as hearing aids and pace makers. Don’t put your phone on pacemakers which means not to put it in the pocket of clothes.

Use your phone promptly

The antenna is straight over your shoulder when you are talking to the phone. Don’t touch the antenna if not necessary.

Emergency calls

Ensure the phone is switched on and in service. Enter the emergency number

Radio frequency (RF) exposure and SAR

This phone meets European Union (EU) requirements concerning exposure to radio waves. Your mobile phone is a radio transmitter and receiver. It is designed and manufactured to not exceed the limits for exposure to radiofrequency (RF) energy, as recommended by the EU Council. These limits are part of comprehensive guidelines and establish permitted levels of RF energy for the general population. The guidelines were developed by independent scientific organizations through the periodic and thorough evaluation of scientific studies. The limits include a substantial safety margin designed to ensure the safety of all persons, regardless of age and health. The exposure standard for mobile phones employs a unit of measurement known as Specific Absorption Rate (SAR).
Specific Absorption Rate (SAR) is the unit of measurement for the amount of radio frequency energy absorbed by the body when using a mobile phone. The SAR value is determined at the highest certified power level in laboratory conditions, but the actual SAR level of the mobile phone while it is operating can be well below this value. This is because the mobile phone is designed to use the minimum power required to reach the network. Variations in SAR below the radio frequency exposure guidelines do not mean that there are variations in safety. While there may be differences in SAR levels among mobile phones, all mobile phone models are designed to meet radio frequency exposure guidelines. Before a phone model is available for sale to the public, it must be tested and certified by the Federal Communications Commission (FCC) that it does not exceed the limit established by the government-adopted requirement for safe exposure. The tests are performed in positions and locations (that is, at the ear and worn on the body) as required by the FCC for each model. For body-worn operation, this phone has been tested and meets FCC RF exposure guidelines when the handset is positioned a minimum of 15 mm from the body without any metal parts in the vicinity of the phone or when used with the original accessory intended for this phone and worn on the body.
Use of other accessories may not ensure compliance with FCC RF exposure guidelines.

The SAR limit recommended by the EU Council is 2.0W/kgA The highest SAR value for this model phone was 0.587W/Kg for 900MHz and 0.062W/Kg for 1800MHz .

SAR tests are conducted using standard operating positions with the phone transmitting at its highest certified power level in all tested frequency bands.

A. The SAR limit for mobile phones used by the public is 2.0 watts/kilogram (W/kg) averaged over ten grams of body tissue. The limit incorporates a substantial margin of safety to give additional protection for the public and to account for any variations in measurements. The SAR values may vary, depending on national reporting requirements and the network band.
