mobile device. Avoid dropping the battery or 
mobile device, especially on a hard surface. If 
your battery or mobile device has been subjected 
to such damage, take it to a Motorola Authorized 
Service Center before using. Do not attempt to 
dry it with an appliance or heat source, such as a 
hair dryer or microwave oven.

battery—particularly when placing it inside a 
pocket, purse, or other container with metal 
objects. Contact with metal objects (such as 
jewelry, keys, beaded chains) could complete an 
electrical circuit (short circuit), causing the 
battery to become very hot, which could cause 
damage or injury.

Promptly dispose of used batteries in 
accordance with local regulations. Contact your 
local recycling center for proper battery 
disposal.

Warning: Never dispose of batteries in a fire because 
they may explode.

New batteries are not fully charged.

Tip: Motorola batteries have circuitry that protects the 
battery from damage from overcharging.

Specific Absorption Rate Data

SAR Data

This model wireless phone meets the 
government’s requirements for exposure to 
radio waves.

Your wireless phone is a radio transmitter and receiver. It 
is designed and manufactured not to exceed limits for 
exposure to radio frequency (RF) energy set by the Federal 
Communications Commission (FCC) of the U.S. 
Government and by the Canadian regulatory authorities. 
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 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 and 
by the Canadian regulatory authorities is 1.6 W/kg.

 Tests 

for SAR are conducted using standard operating positions 
accepted by the FCC and by Industry Canada 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. and Canada, it must be tested and certified to the 
FCC and Industry Canada that it does not exceed the limit 
established by each government 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 and 
available for review by Industry Canada. The highest SAR 
value for this model phone when tested for use at the ear 
is 1.26 W/kg, and when worn on the body, as described in 
this user guide, is 1.58 W/kg. The SAR value for this 
product in its data transmission mode (body-worn use) is 
0.7 W/kg. (Body-worn measurements differ among phone 
models, depending upon available accessories and 
regulatory requirements).

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.
