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.

6

Let’s get started

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.

10

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.

Inserting and removing the SIM

Your phone needs a valid SIM card to work (…To keep it simple, we’ll just
call it ‘SIM’ from now on). Your network connection data and your SIM
address book are saved on the SIM. So, to avoid damaging your SIM or
losing data, try not to touch the metal surface when you’re handling it – and
keep well away from any magnetic or electric source.

here’s what you do…

1. Switch off your phone and disconnect any external power.

2. Remove the back cover and then the battery.

3. Hold your SIM on the cut corner, and slide it

– face down – into the card holder.

4. Insert the battery.

5. Replace the back cover.

1. Switch off your phone.

2. Open the battery cover.

3. Lift the battery up and out of

your phone.

Charging the battery

The rechargeable Li-ion battery that comes with
your phone is ready to use, but is not charged.
That’s easy to do. We’ll show you how below.

The first three times you use the battery, make sure
it’s completely drained before recharging. And then
recharge it fully. That will help to ensure its optimum
performance and a long life.

1. Connect the charger to your phone, and plug it into an 110V/220V

socket.

21

Let’s get started

2.

The battery indicator in the corner of the screen will scroll to show you
it’s charging. If the phone’s battery has been fully drained, the battery
indicator may not immediately appear on the screen when charging
starts. And please don’t worry if the phone and charger become warm
while charging. That’s completely normal.

3. When fully charged, the battery indicator will stop scrolling up and

down.

4. Disconnect the charger from your mobile, and unplug.

Power on/off

Press the power key until the power-on/off icon appears.
When you turn your phone on, it’ll automatically check the SIM and show

the following information on screen:

 Input phone lock code: If you’ve set a lock code.
 Input SIM PIN: If you’ve set a PIN for your SIM.

Note:

The PIN is supplied with your SIM. Please replace it with your

22

Let’s get started

own PIN code as soon as possible. Enter the wrong PIN three
times, and your SIM will be locked. Then you’ll need to contact
your network service provider to ask for a PUK code to unlock
it.

 Searching: The mobile phone will search for the available network.

Care and maintenance

Your phone is a delicate device. The following advice will help you to keep
it looking good and performing well…

 Use a soft dry cloth to clean your phone, battery and charger. Don’t use

liquids such as alcohol, dilution agents or benzene.

 From time-to-time, clean the socket where the charger cable connects

to the phone. Dust tends to gather there. This will ensure a really good
connection.

 Don’t use needles, pen points or other sharp objects on the keypad or

screen.

 Don’t use your phone with wet hands – it could injure you and damage

the phone.

42

Appendix

 Don’t use your phone in dusty or dirty environment.
 Keep your phone away from extremes of heat – like radiators or ovens.

It may explode if it gets too hot.

4RF exposure information (SAR)

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

This phone is designed and manufactured not to exceed the emission limits for
exposure to radio frequency (RF) energy set by the Federal Communications
Commission of the U.S. Government.

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

*

1.6W/kg.
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 opera te a t multiple pow er levels so a s
to use only the poser required to rea ch the ne tw ork. In general, the closer you are to a
wireless base station antenna, the lower the power output.

The highest SAR value for the model phone as reported to the FCC, described in this
user guide, is

Tests for SAR are conducted using standard operating positions accepted

Position 850MHz (W/Kg) 1900MHz (W/Kg)

Head 1.218 1.437

Body 1.437 0.915

Appendix

(Body-worn measurements differ among phone models, depending upon available
accessories and FCC requirements.)

While there may be differences between the SAR levels of various phones and at
various positions, they all meet the government requirement.

The FCC has granted an Equipment Authorization for this model phone with all
reported SAR levels evaluated as in compliance with the FCC RF exposure
guidelines. SAR information on this model phone is on file with the FCC and can be
found under the Display Grant section of http://www.fcc.gov/oet/fccid

after searching

on FCC ID:XXX-XXXXX.
For body worn operation, this phone has been tested and meets the FCC RF

exposure guidelines for use with an accessory that contains no metal and the
positions the handset a minimum of 1.5 cm from the body. Use of other accessories
may not ensure compliance with FCC RF exposure guidelines. If you do no t use a
body-worn accessory and are not holding the phone at the ear, position the ha ndset a
minimum of 1.5cm from your body when the phone is switched on.

This device is compliance with SAR for general population /uncontrolled exposure
limits in ANSI/IEEE C95.1-1999 and had been tested in accordance with the
measurement methods and procedures specified in OET Bulletin 65 Supplement C.
