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.
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 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.
Charging the Battery 1. Make sure that the battery is attached to the phone. 2. Connect the charger to the electrical outlet. 3. Connect the charger to the phone as shown. The flash symbol on the plug must face upwards. 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.
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.

Total Call Time or Call Cost The Call Info menu allows you to check the total time or cost of your calls. To check the time/cost of the last call • Scroll to Call Info, Y E S , Last Call, Y E S .
during a call, and in Last Call and Total Cost in the Call Info menu. To enter the price per call unit 1. Scroll to Call Info, Y E S Options, Y E S , Set Fee, Y E S . 2. Enter your PIN2 and press Y E S . 3. Select Change price. 4. Enter the code for the currency you want, for example USD for US Dollars, and then press Y E S . 5. Enter the price per call unit, for example 0.75, and press Y E S . To enter the decimal point, press #. To revert to call units 1.
Using Two Voice Lines If your subscription supports the Two Line Service, your phone will have two voice lines with different phone numbers, separate bills and perhaps different subscription services. This is useful for example if you want to keep business calls and private calls on separate lines. When you buy your phone, the names of the lines are normally Line 1 and Line 2, but you can change their names. You can only send text messages (SMS) on Line 1.
Voice Control Your phone allows you to: • voice dial - call someone by simply saying the name • answer and reject calls using your voice when connected to a handsfree kit To call someone, you only need to press Y E S until you hear a tone, say the name (voice label) linked with that person and your phone automatically dials the number. To answer or reject calls, say Answer or Busy. Preparing your Phone for Voice Dialing When you buy your phone, voice dialing is set to on.
Note! To use voice dialing with a vehicle handsfree unit, you need to record your voice labels in the car, when connected to a vehicle handsfree. Voice labels for phone book entries recorded in the phone will not be available in the car, and vice versa. For more information about the Vehicle Handsfree unit, see “Vehicle Handsfree” on page 93.
Instead of pressing and holding Y E S , as in step 1 above, you can slide and hold the volume key when the flip is open. A third alternative is to initiate voice dialing by just opening the flip, but then Start on Open must be on. To turn on Start on Open 1. Scroll to Settings, Y E S , Voice Control, Y E S , Start on Open, Y E S . 2. Select On. When Start on Open is on, an icon appears in standby.
Calling Card Calls When making international or long distance calls, you may not want your operator to charge you for these calls on your normal account. If you have a credit card or a calling card, you may want to redirect the charges to one of these accounts instead. The Calling card service lets you redirect the charges to either a credit card account or to a calling card account. You can save two separate card numbers in your phone. These numbers are protected by a four- to eight-digit phone lock code.
Note! Your service provider will give you the information needed for the verification codes. To delete a card number 1. Scroll to Phone Book, Y E S , Calling Cards, Y E S . 2. Scroll to the card number that you want to delete and press Y E S . 3. Select Delete. The question Delete? appears in the display. 4. Press Y E S . The card number has been deleted. To edit a card number 1. Scroll to Phone Book, Y E S , Calling Cards, Y E S . 2. Scroll to the card number that you want to edit and press Y E S . 3.
Sending and Receiving Fax and Data Calls Note! To be able to use various communications services you need the appropriate software such as a fax program, an e-mail program or an Internet browser. Sending Fax and Data Calls All fax and data calls are initiated from the appropriate computer software. To send fax and data calls you need to connect your phone to a computer, for example by means of an infrared modem and then start the appropriate software program.
Receiving Fax and Data Calls – Single Numbering If you have a SIM card that does not support separate fax and data numbers, the phone does not recognize the type of incoming call. Next Incoming Call Type If you want to receive a fax or data call you have to set the phone to one of these options in the Next Incoming sub-menu. You only see this menu if your phone detects that you do not have separate numbers for data, fax and voice.
Extras Alarm Clock The phone has an alarm clock, which you may find useful when travelling. When it is on, an icon is shown in the display. The alarm rings at the time set and the display flashes, even if the phone is turned off. The volume of the alarm signal is always increasing, provided the battery is attached and charged. The alarm rings for 60 seconds and is repeated every nine minutes, if you do not turn it off. After 60 minutes, the repeat function is turned off automatically.
Calculator The phone has a built-in calculator, which can add, subtract, divide and multiply. Press # to get +, -, x, /. • • Press C to delete a figure to the left of the cursor. • Press * to enter a decimal point. To use the calculator In this example we are going to divide 134 by 32. 1. Scroll to Extras, Y E S , Calculator, Y E S . 2. Enter 134. 3. Press # repeatedly until the division sign (/ ) appears. 4. Enter 32. 5. Press Y E S to get the answer. 6.

The timer is shown in standby mode. When the alert sounds, press any key to turn it off. To turn off the timer 1. Scroll to Extras, Y E S , Timer, Y E S . 2. Select Cancel. Note! The timer does not work when the phone is turned off. Games Your phone has two different games for your enjoyment.
Solitaire The object of Solitaire is to form four piles of cards, one per suit, running from ace to king. The cards are dealt out into seven columns. The last six columns have one or more cards facing downwards. If the top card in a column is removed, revealing the face-down card, you may turn it face up. Only kings, or stacks of cards beginning with a king may be moved to an empty column. Columns of cards are built up in descending order and alternating colour.
The Profile Concept Your phone includes a number of pre-programmed profiles. A profile is a group of settings which are set 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 set. Some accessories can choose a profile automatically. For example, when you place your phone in a vehicle handsfree unit, the In Car profile is chosen. For more information on automatic activation of profiles.
The table below shows the settings of each profile.
To change a profile setting 1. Scroll to Settings, Y E S , Profiles, Y E S , Edit profile, Y E S . A list of the profile settings appears. 2. Select a setting by pressing Y E S . 3. Change the profile setting according to your wishes. For information, see the relevant chapters “Personalizing Your Phone” on page 39, “Security for Your Phone and Subscription” on page 58, “Calling Card Calls” on page 79 and “Accessories” on page 90.
Accessories By using your T28 WORLD together with Ericsson original accessories, you have access to a large range of useful features, in addition to those you have when the phone is used separately. • Automatic forward of incoming calls when the phone is placed in a desktop charger • Portable handsfree calling • Handsfree calling in your car • Infrared communication between your phone and computer Note! This is one condition that the specific accessories exist in your market.
Desktop Charger If you use the T28 WORLD with a specific Ericsson Desktop Charger you have access to some useful features besides ordinary charging. You can choose to make the phone switch to the Home profile automatically and forward all calls to your home number when you place your phone in the charger. To be able to use these features, you need to make some settings the first time you place your phone in the desktop charger. Placing the Phone in the Desktop Charger 1.
5. Enter a phone number including the area code (for example, your home number) and press Y E S . A number you used before may be suggested to you. If so, press Y E S to choose the number, or enter another number. 6. The message Automatic activation on? appears. Press Y E S . The message Profile: Home appears to confirm your choice. You can also make these settings later, if you wish. In this case, you need to add the desktop charger to the Home profile, or another profile.
To answer a second call • Press the button on your Portable Handsfree once to answer the waiting call. The current call is now put on hold. When you press the button on your Portable Handsfree again, the second call is disconnected and the first call is retrieved automatically. To voice dial using the Portable Handsfree 1. Press and hold the button on your Portable Handsfree until you hear a tone. 2. Release the button and say a name (voice label) that you have recorded previously.
Tip! If you do not want your phone to switch profile automatically when you connect it to the Advanced Vehicle Handsfree, you need to turn the Auto Activation off. To do this, manually select the In car profile and set the Auto Activation to Off. Note! Your Advanced Vehicle Handsfree should be installed by professional personnel. For more information, please contact your local Ericsson retailer.
Basic Handsfree Basic Handsfree means that the phone handles the call in semi-duplex mode. This means that you cannot speak at the same time as the person at the other end of the line. Use this alternative only if Full Handsfree does not work properly. Full Handsfree Full Handsfree means that the phone handles the call in full duplex mode. This considerably increases the quality of speech, since you do not have to wait until it is your turn to speak.
Infrared modem With an Ericsson infrared modem you can connect your T28 WORLD to a computer via an infrared link. This makes the cable and PC card obsolete. If you want to use the infrared modem with a computer that is running Windows 95/98/NT 4.0, you can install PC software which allows you to manage the phone book in your mobile phone, send and receive SMS messages, fax and data calls, edit your mobile phone’s settings, browse the Internet or connect to your corporate network.
Press Y E S to turn automatic activation on, which means that the profile will be chosen automatically when the accessory is connected. Note! In addition to the portable and vehicle handsfree units, you can add another 12 accessories to a profile. Any accessory above this number will work as ordinary non-profile accessories. You cannot have the same accessory linked with several profiles. To remove an accessory from a profile 1. Scroll to Settings, Y E S , Profiles, Y E S , Accessories, Y E S . 2.
Online Services Imagine that you hear about a new service that your network operator is offering. You call your operator, explain that you want to subscribe to the service and suddenly, within seconds, you have a new menu in your phone that instantly lets you use the new service. You do not need upgraded software for your phone, but you may need to visit your network operator to get a new SIM card. The rest is all taken care of over the air.
New Menu A SIM card which supports the Online Services works in the same way as a normal SIM card. When you have inserted your SIM card and turned on your phone, your network operator may download data to your SIM card. After the first data download and after restarting your phone, the proactive SIM offers a new menu in the phone. The menu offers you new features and services, which can be used instantly. On your T28 WORLD, this menu appears under the Extras menu.
In order for your new SIM settings to take effect, you have to turn off your phone and then turn it on again. Note! After a data download the phone may not work and you will not be able to use it until you restart it. This feature is operator dependent and will probably not happen very often. SIM Card Initiated Features The SIM card may prompt you to make a call. This could happen even if you are already engaged in a call.
