Let’s get started

Let’s get started

Thanks for choosing the R144C. It’s a cdma 2000 1X 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 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.

2

Let’s get started

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 break the terms of your warranty.

broken antenna

 Don’t use your phone if the antenna is damaged, as it could cause injury.

3

Let’s get started

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

 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.

4

Let’s get started

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.
 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.

5

Let’s get started

 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. 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.

6

Let’s get started

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 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.

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.

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

send them to your nearest service centre for inspection.

30

. This device was tested for
typical body-worn operations with the back of the handset kept 10mm from the
body.
To maintain compliance with FCC RF exposure requirements, use accessories that
maintain a 10mm separation distance between the user's body and the back of the
handset. The use of belt clips, holsters and similar accessories should not contain
metallic components in its assembly. The use of accessories that do not satisfy these
requirements may not comply with FCC RF exposure requirements, and should be
avoided.
