Specific Absorption Rate (SAR) information
Your phone has been designed to comply with applicable safety requirements for exposure to radio
waves. These requirements are based on scientific organizations through periodic and thorough
evaluation of scientific studies. These guidelines include safety margins designed to assure the safety of
all persons, regardless of age and health.
The radio wave exposure guidelines employ a unit of measurement known as the Specific Absorption
Rate, or SAR. Tests for SAR are conducted by using standardized method with the phone transmitting at
its highest certified power level in all used frequency bands.
Your phone are designed to meet the relevant guidelines for exposure to radio waves.
Cleaning and Maintenance
The cellular phone, the battery and the charger are not waterproof. Do not use them in places with high
humidity like a bathroom and also avoid spilling any liquids on them.
30
Use a soft cloth to clean the cellular phone, the battery and the charger.
Do not use alcohol, diluted liquid or benzene to clean the cellular phone.
If dust gets in the sockets the phone can be damaged, short-circuit or even lose the ability to be
re-charged. Be sure to clean the socket regularly.
SAR Information
The SAR limit of USA (FCC) is 1.6W/kg Averaged over one gram of tissue. Device types C3001 (FCC ID :
WVBAVVIO105A) has also been tested against this SAR limit. This device was tested for typical
body-worn operations with the back of the handset kept 1.5cm from the body. To maintain compliance
with FCC RF exposure requirements, use accessories that maintain a 1.5cm separation distance
between the user’s body and the back of the handset. The use of belt clips, holsters and similar
accessories should not contain metallic components in its assembly. The use of accessories that do not
satisfy these requirements may not comply with FCC RF exposure requirements, and should be avoided.
Specific Absorption Rate Data
This Model wireless phone meets the government’s requirements for exposure to radio waves.
Your Mobile phone is a radio transmitter and receiver. It is designed and manufactured to exceed limits
for exposure to radio frequency (RF) energy set by the Federal Communication Commission (FCC) of the
U.S Government. These limits are part of comprehensive guidelines and establish permitted levels of RF
energy for the general population. The guidelines are based on standards that were developed by
independent scientific organizations through periodic and thorough evaluation of scientific studies. The
31
standards include a substantial safety margin designed to assure the safety of all persons regardless of
age or health.
The exposure standard for wireless mobile phones employs a unit of measurement known as the Specific
Absorption Rate, or SAR, The SAR limit set by the FCC is 1.6 W/Kg. Tests for SAR are conducted
using standard operating positions accepted by the FCC with the phone transmitting at its highest
certified power level in all tested frequency bands. Although the SAR is determined at the highest
certified power level, the actual SAR level of the phone while operating can be well below the maximum
value. This is because the phone is designed to operate at multiple power levels so as to use only the
power required to reach the network. In general, the closer you are to a wireless base station, the lower
the power output.
Before a phone model is available for sale to the public in the U.S, it must be tested and certified to the
FCC that it does not exceed the limit establish for safe exposure. The tests are performed in positions
and locations (e.g, at the ear and worn on the body) reported to the FCC.
While there may be differences between the SAR levels of various phones and at various positions, they
all meet the governmental requirements for safe exposure. Please note that improvements to this
product model could cause differences in the SAR value for later products, in all cases, products are
designed to be within the guidelines.
Additional information on Specific Absorption Rates (SAR) can be found on the Cellular
Telecommunications & Internet Association (CTIA) Web site:
32
http://www.phonefacts.net
In the United States and Canada, the SAR limit for mobile phones used by the public is 1.6 W/Kg
averaged over one gram of tissue. The standard incorporates a substantial margin of safety to give
additional protection for the public and to account for any variations in measurements.
