Preparing Your Phone for Use 5

You need to do the following to use your phone:

•insert the SIM card

•attach the battery to the phone

•charge the battery

When you register as a subscriber with a network operator, you get a SIM

(Subscriber Identity Module) card. The SIM card contains a computer chip

that keeps track of your phone number, the services included in your

subscription, and your Phone Book information, among other things.

SIM cards come in two sizes. One is the size of a credit card and the other is

smaller. Your phone uses the smaller card. Many credit card-sized SIM cards

have a perforated smaller card that you can take out easily. Before you can use

your phone, you must insert the SIM card as shown below.

Inserting and Removing the SIM Card

1. Remove the battery if

attached. Slide the SIM card

into the slot, under the silver

colored holders, with the

golden connectors facing

down and the cut corner to

the right.

2. Raise the edge of the SIM card

and slide it out.

The PIN

Most SIM cards are supplied with a security code, also known as PIN

(Personal Identity Number), which you need to access the network.

Every time you turn on your phone, you are asked to enter your PIN. You will

find your PIN in the information from your operator.

Some operators may have services that require a second PIN, your PIN2.

You should be careful with your PIN, since it is your protection against

unauthorized use of your subscription.

6 Preparing Your Phone for Use

If your PIN is entered incorrectly three times in a row, the SIM card is

blocked. If this happens, you can unlock it by using your PUK (Personal

Unblocking Key code), which you also get from your operator.

Your T28 WORLD comes with a lithium battery. The battery is not charged

when you buy your phone, but there may be enough power to switch the

phone on. We recommend that you charge the battery up to three hours before

you use the phone for the first time.

Attaching the Battery to Your Phone

When to Charge the Battery

The battery that comes with your phone can be charged whenever you wish

without affecting its performance. You can also charge the battery when the

phone is off.

Toremindyouthatyouwillsoonneedtochargethebatteryorreplaceitwith

a charged one:

•an alarm signal (a short beep) sounds and the message

Attention! Battery low

appears in the display

•the indicator light on top of the phone starts flashing red

If you have an Ericsson-approved battery, you can check the remaining talk

and standby times in the Status menu by sliding the volume key upwards or

downwards in standby mode. You can move downwards in the menu by

pressing d. The remaining standby and talk times depend on the type of

battery you use and your position in the network. Please note that these times

are approximate and you may have 20% less time than is shown in the display.

Note! The phone turns itself off when the battery can no longer power it

satisfactorily.

The Battery

•Place the battery on the back of the phone and push until you hear a click.

Charging the Battery

Note! The electrical plug may look different depending on the electrical outlet

in your country. Do not connect it to any other item than your Ericsson Travel

Charger CTR-10. It must not be disconnected from the charger when plugged

into the electrical outlet.

To indicate charging:

•the indicator on the top of the phone shows a steady red light (or green,

if the phone is switched on)

•the message

Charging only

is shown in the display

•the battery meter in the display pulses continuously

Note! If you charge a new battery that is empty, or a battery that has not been

used for a long time, it may take a while until you get an indication of

charging in the display.

An Ericsson-approved battery is indicated by

Ericsson Optimized charging

each

time you start charging the battery when the phone is switched on. For the best

charging, talk and standby times in the long run, we recommend that you use

only Ericsson-approved batteries with your phone.

Batteries that are not Ericsson-approved are charged slowly for safety reasons.

These are indicated by

Charging alien battery

each time you start charging the

battery when the phone is switched on.

Tip! You can use the phone while the battery is being charged. However, this

lengthens the charging time.

3. Connect the charger to the phone

as shown. The flash symbol on the

plug must face upwards.

1. Make sure that the battery is

attached to the phone.

2. Connect the charger to the

electrical outlet.

Network Search

After you have turned on the phone (and entered your PIN), the phone

searches for a network.

When a network is found, the phone beeps three times. The indicator light on

top of the phone flashes green once every second and your network operator’s

name (in most cases abbreviated) appears in the display.

This is called standby mode. You can now make and receive calls.

Note! See “Error Messages” on page 104, if you do not reach standby.

The first time you turn on your phone, you may want to choose the ring signal

type and set the clock and date. For more information about these and other
