Let’s get started
Let’s get started
Thanks for choosing the ZTE U5100. It’s a GSM dual band GPRS digital
mobile phone, which we’ll simply call ‘phone’ from now on.
If you’d like your phone to live a long and fruitful life, please read this guide
carefully and keep it for future reference. You never know when you might
need it.
And don’t worry if the pictures we use to demonstrate your phone’s
functions look a little different from what you see on its screen. It’s the
functions they show that matter.
Lost or stolen?
If your phone goes missing, please tell your service provider as soon as
you know. That way other people can be barred from using it.
Obviously, it’s best to keep your phone with you at all times, and we’d
strongly advise you to set a PIN, and change it from time to time.

Using your phone safely
on the road
Using a phone while driving is illegal in many countries. Please follow
local laws and drive safely at all times.
near sensitive electronics
Don’t use your phone near sensitive electronic equipment – particularly
medical devices such as pacemakers – as it could cause them to
malfunction. It can also interfere with the operation of fire detectors and
other automatic-control equipment.
For more information about how your phone affects pacemakers or
other electronic equipment, please contact the manufacturer or your
local distributor.
Your phone may cause interference when used near TVs, radios or
automated office equipment.
while flying
7
Let’s get started
Your phone can cause interference with aircraft equipment. So it’s
essential you follow airline regulations. And if airline personnel ask you
to switch off your phone, or disable its wireless functions, please do as
they say.
in hospital
Your phone may interfere with the normal operation of medical
equipment. Follow all hospital regulations and turn it off when you’re
asked to by posted warnings or medical staff.
at a petrol station
Don’t use your phone at petrol stations. In fact, it’s always best to switch
off whenever you’re near fuels, chemicals or explosives.
around water
Keep your phone away from water (or any other liquid). It’s not a
waterproof model.
making repairs
8
Let’s get started
Never take your phone apart. Please leave that to the professionals.
Unauthorised repairs could break the terms of your warranty.
broken antenna
Don’t use your phone if the antenna is damaged, as it could cause
injury.
around children
Keep your mobile out of children’s reach. It should never be used as a
toy and it might not be good for their health.
original accessories
Only use the original accessories supplied with your phone or those
approved by the manufacturer. Using unapproved accessories may
affect performance, make the warranty void, break national regulations
on the use of mobile phones, or even cause injury.
near explosives
9
Let’s get started
Turn off your phone in or near areas where explosive materials are
used. Always obey local laws and turn off your phone when requested.
emergency calls
To make an emergency call your phone must be turned on and in an
area where there’s network coverage. Dial the national emergency
number and press ‘send’. Explain exactly where you are and don’t hang
up until help has arrived.
working temperature
The working temperature for the phone is between 0 and 40 . ℃℃
Please don’t use the phone outside the range. Using the phone under
too high or too low temperature might cause problems.
At very high volume, prolonged listening to a mobile phone can
damage your hearing.

Let’s get started
Battery care and safety
Keep the battery in a cool, ventilated place and out of direct sunlight.
Although the battery is rechargeable, it’ll eventually start to lose its
ability to recharge. If you find that the battery won’t recharge, it’s time to
replace it.
Please don’t throw old batteries into your household rubbish. You’ll find
there are special bins for batteries at refuse collection points. And some
high street electrical stores provide a battery recycling service too.
Never throw the battery into a fire – it’s highly inflammable and could
explode, hurting you or somebody else.
When you put the battery into your phone, there’s no need to use force.
Exerting too much pressure could make it leak, overheat, explode or
burst into flame.
Never take the battery apart. This may result in leakage, overheating,
explosion or fire.
If the battery becomes hot, changes colour or shape at any time (when
in use, charging or even while in storage) please stop using it
immediately and replace.
11
Let’s get started
Keep the battery dry. Damp or wet conditions can cause it to overheat
or corrode.
Don’t leave the battery in direct sunlight or anywhere really hot, like in a
car on a summer’s day. That could make it leak or overheat, while
lowering its performance and shortening its life.
Don’t charge the battery continuously for 24 hours. Overcharging is not
good for it.
Note:
Please avoid contact with the materials inside a damaged or
leaking battery. If they get on your skin, wash with lots of water
and seek medical assistance if required.
Charger care and safety
Only plug into voltages between 110VAC and 220VAC. Using a voltage
outside that range can damage the phone/charger – and cause the
battery to leak or catch fire.
12
Let’s get started
Never short-circuit the charger – this may cause electrocution,
overheating or damage.
Don’t charge the phone in direct sunlight or in an area where it’s damp,
dusty, or on a vibrating surface. And charging your phone near – or on –
a TV or radio could interfere with transmission.
Don’t use the charger if the power cable is damaged. It may cause a fire
or give someone an electric shock.
Keep water well away from the charger. If the charger does get
splashed by water, or any other kind of liquid, immediately unplug it to
avoid overheating, fire or electrocution.
Don’t take the charger apart. It could cause injury, give you an electric
shock or catch fire.
Never touch any charger, electric cable or socket with wet hands.
Don’t place heavy objects on the electric cable.
If the cable is damaged, don’t try to mend it yourself – it could cause a
fire or electrocute you.
Always unplug the charger before you clean it.
13
Let’s get started
When unplugging the charger, hold the plug itself, rather than pulling on
the cable. A damaged cable can cause electrocution or fire.
