Thank you for purchasing the B400 GSM. Please read all
information carefully before getting stared to install and use the
Mobile. This would help you to make good use of this mobile and
fully understand the functions of mobile and be easy to operate.
B400 GSM is aimed to design for GSM/GPRS network. B400 GSM
complies with GSM/GPRS Technique regulations and it is certified
by internal and external authorities.
Breaking the rules may be dangerous or illegal.
1. 2 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.
4
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
5
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
.
6
SAR tests are conducted using standard operating positions with the
phone transmitting at its highest certified power level in all tested
frequency bands.
Use only approved batteries. Use of any unauthorized accessories
could damage you and your phone and may be dangerous. If
jewelry, keys, beaded chains, or other conductive materials touch
exposed battery terminals, this could complete an electrical circuit
(short circuit), become very hot, and could cause damage or injury.
Never use a charger or battery that is damaged.
Use the battery only for its intended purpose.
If you use the phone near the network’s base station, it uses less
power. Talk and standby time are greatly affected by the signal
strength on the cellular network and the parameters set by the
network operator.
Battery charging time depends on the remaining battery charge,
the type of battery, and the charger used. The battery can be
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.

charged and discharged hundreds of times, but it will gradually
wear out. When the operation time is noticeably shorter than
normal, it is time to buy a new battery.
If left unused, a fully charged battery will discharge itself over
time.
Use only approved batteries, and recharges your battery only
approved chargers. Disconnect the charger from the power
source when it is not in use. Do not leave the battery connected
to a charger for more than a week, since overcharging may
shorten its life.
Extreme temperatures will affect the charging capacity of your
battery: it may require cooling or warming first.
Do not leave the battery in hot or cold places because the
capacity and lifetime of the battery will be reduced. Try to keep
the battery at room temperature. A phone with a hot or cold
battery may not work temporarily, even when the battery is fully
charged.
Do not short-circuit the battery. Accidental short-circuiting can
occur when a metallic object like a coin, clip or pen causes a
direct connection between the + and – terminals of the battery
(metal strips on the battery). For example, do not carry a spare
battery in a pocket or bag where the battery may contact metal
objects. Short-circuiting the terminals may damage the battery or
the object causing the short-circuiting.
Dispose of used batteries in accordance with local regulations.
Always recycle. Do not dispose of batteries in a fire.
The phone could explode if the battery is replaced with an
incorrect type.
8
Dispose of used batteries according to the manufacturer’s
instructions.
At very high volumes, prolonged listening to a headset can
damage your hearing.
To avoid risk of personal injury, do not dispose of your battery in
a fire.
Do not throw your battery or mobile device in the trash.
