Preparing Your Phone for Use
Overview

Front

Back
Assembly
You need to do the following to use your phone:
insert the SIM card
attach the battery to the phone
charge the battery
The SIM Card
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

-
Remove the battery if attached. Slide the SIM card into the slot, under the silvery holders, with the golden connectors facing down and the cut corner to the right.
-
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.
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.
The Battery
Your T28 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


- Place the battery on the back of the phone and push until you hear a click.
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.
To remind you that you will soon need to charge the battery or replace it with 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 . 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.
Charging the Battery

- Make sure that the battery is attached to the phone.
-
Connect the charger to the mains.
-
Connect the charger to the phone as shown. The flash symbol on the plug must face upwards.
Note! The mains plug may look different depending on the mains socket in your country. Do not connect it to any other item than you Ericsson Travel Charger CTR-10. It must not be separated from the charger when plugged into the mains socket.
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. Only then can you switch on and use your phone.
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.
When the battery is fully charged, the battery meter in the display is full and the indicator on the top of the phone shows a steady green light.
Disconnecting the Charger
Disconnect the charger from the phone by moving the plug upwards.

Removing the Battery

- Slide the release catch upwards.

- Lift the battery away from the phone.
Turning Your Phone On and Off
Turning your Phone on
- Open the flip by pressing the flip release button on the right side of the phone.
- Press and hold the NO key until you hear a tone.
If "PIN:" Appears in the Display
Some SIM cards are protected with a PIN code. If PIN: appears in the display after you have turned on the phone:
- Enter your PIN. If you make a mistake while entering your PIN, erase the wrong number by pressing the C key.
- Press YES.
Note! If your PIN is entered incorrectly three times in a row, the SIM card is blocked. You can unblock it by using your PUK. See "The SIM Card Lock" on page 58.
If 'Phone locked' appears in the display, enter your phone lock code. See "The Phone Lock" on page 59.
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 106, if you do not reach standby.
Initial Settings
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 settings, see "Personalizing Your Phone" on page 39.
Display Language
Most modern SIM cards automatically set the display language to the language of the country where you bought your SIM card, (Automatic). If this is not the case, the preset language is English. To change the display language, see "Display Language" on page 43.
If your phone shows a language that you do not understand, you can change it to Automatic, or English, in the following ways:
To change the display language to Automatic
- If not in standby mode, press and hold the NO key to go to standby.
- Press the arrow key.
- Enter 8888.
- Press the arrow key.
To change the display language to English
- If not in standby mode, press and hold the NO key to go to standby.
- Press the arrow key.
- Enter 0000.
- Press the arrow key.
Turning Your Phone Off
- In standby mode, press and hold the NO key until you hear a tone.

T28 Features
Your T28 is a small new generation phone: a Dual Band phone with a lithium battery; a phone of modern design and advanced technology.
The active flip makes it possible for you to answer by just opening the flip. Or why not use the Voice Control and say 'Answer' to answer a call or 'Busy' if you wish to reject the call. You can also call a person by simply saying the name.
The T28 has a 'Profile' feature which makes it possible for you to change a few settings by just choosing a certain Profile, since each profile includes a group of settings preset to suit a certain environment. For example, when you go to a meeting, you can just choose the 'Meeting' profile and a number of settings that suit a meeting are then set automatically.
The Profiles are also related to intelligent accessories such as a desktop charger, a portable or vehicle handsfree. For example, you may place the T28 in a vehicle handsfree kit and the 'In Car' profile is chosen automatically.
In the display of the T28 you can see a mixture of text and symbols, which makes it easier for you to move through the menus when you want to change a certain setting, turn on the Vibrating Alert, send a message, save a number and so on.
An extra feature is the numbered shortcuts, which takes you to a certain setting quickly and easily. You may also create your own favourite menu, 'My Shortcuts', by including the settings you use most often. If you should need help using the menus, the T28 is equipped with help texts to guide you.

Using the Menu
You can find all your phone functions in the menus. You use the menus every time you want to change a setting in your phone, such as the ring signal. You also use the menus to get the most out of your phone: to set the alarm clock, send text messages, save important phone numbers, etc.
The menus are arranged in a loop, which you enter and move (scroll) through with the and keys or by using shortcuts. Each menu contains a list of options. Some menus have sub-menus with additional options.

Your Personal Phone Book
You can create a personal phone book by saving phone numbers and accompanying names (an entry). An easy way to make calls is by recalling the phone numbers or names saved in your phone book.
Creating a Personal Phone Book
Before you start creating your personal phone book, there are a few things you need to know. You need to learn about the memories, how to save the numbers with the international (+) sign and how to enter letters.
Phone Book Memories
You can save phone numbers and names in:
the card memory on the SIM card
the phone memory
Your entries are first saved in the positions on your SIM card. The actual number of memory positions available depends on your SIM card.
Saving your numbers in the card memory allows you to use the numbers saved on the SIM card even when you change phones, i.e. when you insert your SIM card into another phone.
By saving your numbers in the phone memory, they are always available to you in your phone, even if you change SIM cards. The phone memory holds 99 positions in which your entries are saved when all SIM positions are occupied.
International Numbers
If you intend to use your phone both at home and abroad, it is a good idea to save all phone numbers as international phone numbers, i.e. with the (+) sign, (which automatically replaces the international dialling prefix for the country you are calling from) followed by the country code, the area code and the phone number.
To enter an international phone number
- Press and hold 0 to enter the + sign. Exclude the leading zero in the area code.
Entering Letters
You can enter letters when you use the phone book and when you compose a short message (SMS). See "Sending and Receiving Text Messages (SMS)" on page 46.
Press the appropriate key, 1-9, 0 or #, repeatedly until the character you want appears in the display.
