Important

This section describes the information that is important to know before you use the Cordless phone and the functions described.

Note: This user guide describes the supported BusinessPhone Communication Platform functions together with the most commonly used telephone specific functions. All telephone specific functions are listed in the menu structure "Menu structure" on page 12.

Preparing for use

Before using your Cordless the first time you have to charge and connect the battery, see section "Installation" on page 88.

Note: Place the Cordless in the charger and charge it for at least one hour before using it the first time.

Guidelines

Consider these suggestions and guidelines to keep your telephone in good shape and working properly.

Intrinsic safety

The Cordless DT400, DT410 and DT420 are IP54 classified, which means that they are not specified as intrinsically safe. Do not use them in hazardous areas.

Only the DT430 is designed for environments requiring intrinsically safe equipment and therefore IP64 and EX-classified.

Battery handling

The NiMH battery contains environmental polluting material. If damaged, return it to a collecting point.

Note: Only use the charger that is delivered with your Cordless to charge the battery.

Cleaning

Clean the Cordless only with a soft, water dampened cloth. Using soap or any other cleaning materials may discolor or damage the Cordless.

Treatment

Although the Cordless telephones are resistant to water spray, dust and soil, you should handle your phone always with care. Do not expose the Cordless to direct sunlight for long periods and keep your phone away from excessive heat.

Group Facilities

When you are working together in a team the following group facilities can be very useful.

Group hunting

Your telephone can be included in one or several hunt groups. In a hunt group all members are represented with one common directory number. 16 hunt groups can be programmed, each containing 1 to 20 members. A member can be either an extension number, an operator console or a fictive number. Please ask your system administrator if you require this function.

Note: The number of cordless extensions in a hunt group is limited to eight (including tandem configurations).

Incoming calls to the hunt group are directed to free extensions in the group. The hunt order within the group can be changed to suit your needs. If all members of the hunt group are busy an incoming call is being queued. If no one answers an incoming call before the programmed time, the call is forwarded to the programmed answering position (e.g. operator).

Note: If all members in a hunt group are busy, the call-back or intrusion functions are not available.

Log in

Before you can answer group hunting calls, you must log in.

To log in to one hunt group:

Press

Dial the common bell pick up code

Ask your system administrator for the common bell pick up code.

If two or more extensions simultaneously attempt to answer a call from the common bell extension, only the first extension will pick it up. The other extensions will receive the “number unobtainable” tone. This will also happen if you dial the common bell pick up code and there are no calls waiting at the common bell extension.

Other Useful Facilities

By using these facilities your productivity will be increased, e.g. you can set reminders for important meetings, place the costs for external calls on separate accounts and much more ...

Account number

An account number can be entered to debit telephone costs to different accounts. Depending on the system configuration the account number has to be entered from a verified account number list (predefined) or you can invent an own account number. The following prerequisites apply:

• With the verified account number you can restrict the making of external calls (not a specific number or area), so everyone who is allowed to make external calls will receive an account number which has to be used each time he/she wants to make an external call.
• Verified account numbers contain up to 10 digits.
• Own account numbers contain up to 15 digits.

The account numbers can also be used via the DISA function, see section “Direct Inward System Access (DISA)” on page 55.

Direct Inward System Access (DISA)

If you are working externally and you have the need to make business calls, call your company and use the company PBX to build up an external call to the desired party. You just pay the costs for the phone call to your company. The other costs will automatically be placed on your extension number or on a special project.

Note: To activate this function, you have to change the default password from "0000" to a personal one. Which code to use and how to change it, see section "Select password" on page 62.

You can also divert calls from your office extension to your external position, see section "Call Forwarding" on page 23. During the procedure you will be prompted for your password. See last page for a card to remember these specific numbers.

Networking

Networking is the connection of several premises within a company. The connection can be set up via leased lines, public lines, Local Area Network (LAN) or Wide Area Network (WAN). Ask your system administrator about details regarding networking.

IP calls

IP calls are internal calls sent via an internal data network (LAN or WAN) and the transfer of data and voice is made on the same line. If you are connected to an internal data network the IP connection is made automatically. To minimize the traffic on the network the speech quality is decreased.

If the speech quality is not acceptable you can disconnect the IP call and switch to a non-IP call (alternative network). The switch from the IP net to the non-IP net is made during the call, so the call does not have to be disconnected.

If you want to switch to a non-IP net during the call:

Press

*61*

Dial

During the procedure the other party is put on hold. When the procedure is ready you will receive a special ringing tone and the call is resumed in the non-IP net.

Note: A switch to a non-IP call can only be performed if the original call is an IP call, otherwise you will receive a blocking tone.

Lock the keypad

You can lock your keypad to avoid accidental activation or dialling a number by mistake. The following procedure describes the manual lock, but it is recommended to always have the automatic lock on.

Useful Hints

Connections between external lines

With your BusinessPhone Communication Platform, you can establish an external call diversion or a conference with more than one external party or transfer an external call to another external destination (e.g. a mobile phone). These features are very useful for everyday business life.

Note: When these features are used, your BusinessPhone Communication Platform will occupy at least two external lines.

However, there may be disadvantages in connecting to several external lines. We would therefore like to draw your attention to the following:

• Please do not transfer external calls to an external mailbox, to information systems or to external parties before they have answered
• Try to avoid diverting calls to third parties before they have answered
• If you are connected to two external lines, cancel one call by pressing the "R"-key and the "1"-key

If the external parties are not persons (mailbox, automated information or attendant systems, etc.), connections on external lines can last a long time, which can be costly. Moreover, such calls may occupy two of your system's external lines. You can restrict connections between the external lines by reprogramming your system.

Please ask your system administrator or contact our service centre for more information.

Installation

This chapter describes how to connect and charge the battery of your Cordless.

Note: If you are using the DT430 or another phone that was equipped with an intrinsically safe battery for EX-classification, you need to loosen the screws at the back of the phone, see "DT430" on page 90 in this section.

DT400 / DT410 / DT420

The DT400, DT410 and DT420 are supplied with a high capacity nickel metal hydride (NiMH) battery. If you have more than one battery available, you charge only the battery.

Removing the battery

To remove the battery, use the two plastic ribbed plates at the short side of the Cordless.

Pull the plates towards the middle of the telephone

Fitting the battery

Press the battery firmly and pull the plates from the middle and out

DT430

The DT430 telephone is designed for usage in rough environments. This Cordless is safe to use in explosion risk environments (EX-classification) and therefore is equipped with a special battery.

Removing and fitting the battery for intrinsically safe phones

To remove and fit the battery, you have to use the screws at the back of your phone, as shown below. You do not have to use the ordinary plates to release and fasten the battery.

Use the screws on the back of the battery

Battery performance

All Cordless are supplied with a high capacity nickel metal hydride (NiMH) battery. The table below indicates the performance.

	Tak time (hours)	Standby time (hours)	Charge time (minutes)
High capacity NiMH battery:	10 100 60

Charging the battery

When the battery requires charging, you will hear an attention beep and the display will show the "Low battery" icon.

Place the Cordless in the desktop charger as shown in the figure below

The charging process will start automatically, indicated by a red light on the charger. It takes approximately one hour to fully charge the battery.

Line drawing of a hand holding a handheld mobile phone with keypad and buttons (no text or symbols)

The handset is fully operational while stored in the desktop charger. If you have another battery, you can also place just the battery alone in the desktop charger.

When charging is complete, the charger light will turn green.

Notes:

Do not connect your Cordless to the charger without a battery.

If the battery is completely flat it can take a few minutes before the red light on the charger is lit.

If the standby time for your Cordless becomes too low, you should replace the battery.

Only use the charger that is delivered with your Cordless to charge the battery.

It is normal for the battery to get slightly warm while charging.

SIM Card

All your personal settings in the handset are programmed and stored in the Subscriber Identity Module (SIM) card.

The SIM card provides you with personal mobility as you can easily move it to another Cordless telephone, enabling you to receive calls, make calls and keep all your personal settings such as phone book, identity and alert signal.

Changing the SIM Card

Note: Change the SIM Card only in an environment without static electricity.

Remove the battery

See section "Removing the battery" on page 88. The SIM card is placed under the battery unit in a hatch in the middle.

Move the steel plate forward to open the hatch

You see the labels "OPEN" and "LOCK" on the steel plate. Push the steel plate carefully in one of the directions.

Lift the hatch and remove the SIM card

Now you can place it in another Cordless.

Press the hatch and move the steel plate forward to lock

Fit the battery

See section "Fitting the battery" on page 89.

Optional Accessories

You can customize your Ericsson telephone to meet your own needs. All of the following accessories are optional and can be purchased at your local Ericsson contact.

Available accessories for your Cordless:

• desktop charger
• battery pack NiMH with headset connector
• headsets for hands-free communication
• headset with hearing protection for noisy environments
• belt clip, hinge type
• belt clip, click-on type
• leather case
• security chain

Note: If you require EX-classification for intrinsically safe usage in explosive environments, you cannot use a headset or the headset special battery.
