13 Warnings and Precautions  
This section contains important information pertaining to the 
operating instructions of your device. It also contains 
information about how to use the device safely. Read this 
information carefully before using your device.  
Electronic Device 
Power off your device if using the device is prohibited. Do not 
use the device when using the device causes danger or 
interference with electronic devices.   
						

							22 
Medical Device 
 Follow rules and regulations set forth by hospitals and health 
care facilities. Do not use your device when using the device 
is prohibited.  

 Pacemaker manufacturers recommend that a minimum 
distance of 15 cm be maintained between a device and a 
pacemaker to prevent potential interference with th e 
pacemaker. If you are using a pacemaker, use the device on 
the opposite side of the pacemaker and do not carry the 
device in your front pocket.  

 Some wireless devices may affect the performance of hearing 
aids. For any such problems, consult your service provider.  

 To ensure that the Hearing Aid Compatibility rating for your 
device is maintained, secondary transmitters such as 
Bluetooth components must be disabled during a call.  
Potentially Explosive Atmosphere 
Power off your device in any area with a poten tially explosive 
atmosphere, and comply with all signs and instructions. Areas 
that may have potentially explosive atmospheres include the 
areas where you would normally be advised to turn off your 
vehicle engine. Triggering of sparks in such areas could c ause an 
explosion or a fire, resulting in bodily injuries or even deaths. Do 
not power on your device at refueling points such as service 
stations. Comply with restrictions on the use of radio equipment 
in fuel depots, storage, and distribution areas, and chemical 
plants. In addition, adhere to restrictions in areas where blasting 
operations are in progress. Before using the device, watch out 
for areas that have potentially explosive atmospheres that are  
						

							23 
often, but not always, clearly marked. Such locations include 
areas below the deck on boats, chemical transfer or storage 
facilities, and areas where the air contains chemicals or particles 
such as grain, dust, or metal powders. Ask the manufacturers of 
vehicles using liquefied petroleum gas (such as propane  or 
butane) whether this device can be safely used in their vicinity.  
Traffic Security 
Observe local laws and regulations while using the device. In 
addition, if using the device while driving a vehicle, comply with 
the following guidelines:  

 Concentrate on  driving. Your first responsibility is to drive 
s a f e l y.  

 Do not talk on the device while driving. Use hands -free 
accessories.  

 When you have to make or answer a call, park the vehicle at 
the road side before using your device.  

 RF signals may affect electroni c systems of motor vehicles. 
For more information, consult the vehicle manufacturer.  

 In a motor vehicle, do not place the device over the air bag 
or in the air bag deployment area. Otherwise, the device may 
hurt you owing to the strong force when the air b ag inflates. 

 Do not use your device while flying in an aircraft. Power off 
your device before boarding an aircraft. Using wireless 
devices in an aircraft may cause danger to the operation of 
the aircraft and disrupt the wireless telephone network. It 
may a lso be considered illegal.   
						

							24 
Operating Environment  Do not use or charge the device in dusty, damp, and dirty 
places or places with magnetic fields. Otherwise, it may result 
in a malfunction of the circuit.  

 The device complies with the RF specifications when the 
device is used near your ear or at a distance of 1.5 cm from 
your body. Ensure that the device accessories such as a 
device case and a device holster are not composed of metal 
components. Keep your device 1.5 cm away from your body 
to meet the requirem ent earlier mentioned.  

 On a stormy day with thunder, do not use your device when 
it is being charged, to prevent any danger caused by 
lightning.  

 When you are on a call, do not touch the antenna. Touching 
the antenna affects the call quality and results in increase in 
power consumption. As a result, the talk time and the 
standby time are reduced.  

 While using the device, observe the local laws and 
regulations, and respect others' privacy and legal rights.  

 Keep the ambient temperature between 0°C and 40°C whil e 
the device is being charged. Keep the ambient temperature 
between 0°C to 40°C for using the device powered by a 
battery.  
Prevention of Hearing Damage  
Using a headset at high volume can damage your hearing. To 
reduce the risk of damage to hearing, lower the headset volume 
to a safe and comfortable level.  
						

							25 
Safety of Children

times before it eventually wears out. When the standby time 
and the tal k time are shorter than the normal time, replace 
the battery.  

 Use the AC power supply defined in the specifications of the 
charger. An improper power voltage may cause a fire or a 
malfunction of the charger.  

 Do not connect two poles of the battery with con ductors, 
such as metal materials, keys, or jewelries. Otherwise, the 
battery may be short- circuited and may cause injuries and 
burns on your body.   
						

							26

does not touch your skin and eyes. When the electrolyte 
touches your skin or splashes into your eyes, wash your eyes 
with clean water immediately and consult a doc tor. 

 If there is a case of battery deformation, color change, or 
abnormal heating while you charge or store the battery, 
remove the battery immediately and stop using it. Otherwise, 
it may lead to battery leakage, overheating, explosion, or fire.  

 If the po wer cable is damaged (for example, the cord is 
exposed or broken), or the plug loosens, stop using the cable 
at once. Otherwise, it may lead to an electric shock, a short 
circuit of the charger, or a fire.  

 Do not dispose of batteries in fire as they may ex plode. 
Batteries may also explode if damaged.  

 Danger of explosion if battery is incorrectly replaced. Recycle 
or dispose of used batteries according to the local 
regulations or reference instruction supplied with your device.

communications. 
Certification Information (SAR)  
This device meets guidelines for exposure to radio waves.  
Your device is a low -power radio transmitter and receiver. As 
recommended by international guidelines, the device is  designed 
not to exceed the limits for exposure to radio waves. These 
guidelines were developed by the independent scientific 
organization International Commission on Non -Ionizing 
Radiation Protection (ICNIRP) and include safety measures 
designed to ensure  safety for all users, regardless of age and 
health.   
The Specific Absorption Rate (SAR) is the unit of measurement 
for the amount of radio frequency energy absorbed by the body 
when using a device. The SAR value is determined at the highest 
certified powe r level in laboratory conditions, but the actual SAR 
level of the device when being operated can be well below the 
value. This is because the device is designed to use the minimum 
power required to reach the network.  
The SAR limit adopted by USA and Canada  is 1.6 watts/kilogram 
(W/kg) averaged over one gram of tissue. The highest SAR value 
reported to the FCC and IC for this device type when tested for 
use at the ear is 0.878 W/kg, and when properly worn on the 
body is 0.875 W/kg.  
FCC Statement 
This equipment has been tested and found to comply with the 
limits for a Class B digital device, pursuant to Part 15 of the FCC 
Rules. These limits are designed to provide reasonable 
protection against harmful interference in a residential
