Let’s get started

Let’s get started

Thanks for choosing the F231. It’s a GSM 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 phone lock code, and change it from time to
time.

1

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

 Your phone c an 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

 Never take your phone apart. Please leave that to the professionals.

Unauthorised repairs could br ea k the terms of your w arranty.

3

Let’s get started

broken antenna

 Don’t use your phone if t he anten na is dam aged, as i t coul d caus e

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 acce ssor ie s supplied with your phone or those

approved by the manufacturer. Using unapproved accessories may
affect performance, make the warranty void, brea k na tional regulations
on the use of mobile phones, or even cause injury.

near explosives

 Turn off your phone in or near areas where explosive materials are

used. Always obey local laws and turn off your ph one when
requested.

4

Let’s get started

emergency calls

 To make an emergency cal l 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.

Battery care and safety

 Keep the battery in a cool, ventilated place and out of direct sunlight.

5

Let’s get started

 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.

 Keep the battery dry. D a mp or w et conditions can cause it to ov erheat

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

6

Let’s get started

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.

 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

7

Let’s get started

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.
 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 y ou do…

1. Switch off your phone and disconnect any

external power.

2. Remove the back cover.

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

down – into the card holder.

4. Replace the back cover.

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 socke t.

2. The battery indicator in the corner of the screen will

scroll right and left to show you it’s charging. And
please don’t worry if the phone and charger become
warm while charging. That’s completely normal.

scrolling.

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

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.

 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.

 If your phone gets wet and the colour of the label on it changes, the

warranty will be void, even if the warranty period hasn’t expired.

36

Appendix

 If there’s anything wrong with the phone, battery, charger, or any

accessory, please send them to your nearest service centre for
inspection.

FCC regulations

 This mobile phone complies with part 15 of the FCC Rules. Operation is subject

to the following two conditio ns : (1 ) This devic e ma y not cause harmful
interference, and (2) this device must accept any interference received,
including interference that may cause undesired operation.

 This mobile phone 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
installation. This equipment generates, uses and can radiated radio frequency
energy and, if not in st al l ed a nd u sed in accor dan ce w ith th e in str uc t ions , may
cause harmful interference to radio communications. However, there is no
guarantee that interference will not occur in a particular installation If this
equipment does cause harmful interference to radio or television reception, which
can be determined by turning the equipment off and on, the user is encouraged to
try to correct the interference by one or more of the following measures:

-Reorient or relocate the rec ei ving antenna.

-Increase the separation between the equipment and receiver.

-Connect the equipment into an outlet on a circuit different from that to which

37

Appendix

the receiver is connecte d.

-Consult the deale r or an e xperienced radio/TV technic i an for help.

Changes or modifications not expressly approved by the party responsible for
compliance could void the user‘s authority to operate the equipment.

 The antenna(s) used for this transmitter must not be co-located or operating in

conjunction with any other antenna or transmitter.

38

Appendix

RF 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.
accepted by the FCC with the phon e 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 poser required to reach the network. In
general, the closer you ar e to a wirel ess base station antenna, the lower the power
output.

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

Device types ZTE F231 (FCC ID: SRQ-F231) has also been tested against this SAR
limit.The highest SAR value reported under this standard during product certification
for use when properl y worn on the bo dy is 0.667 W/kg and for head is 0.273 W/kg.
Simultaneous RF exposure is 0.749W/Kg.

Tests for SAR are conducted using standard operating positions
