1 General Information

Batteries

Do not use any other kind of rechargeable batteries, as these could possibly lead to a short circuit. When changing the battery, always use a new battery, type AAA 1.5V.

Do not throw batteries into the fire or immerse them in water. Do not dispose of old or faulty batteries with normal household waste.

Connection information

The unit requires a TAE socket with F/N coding, in common with other plug-in units with N coding such as fax machines, answering machines, or modems.

Location

Do not position the telephone in the immediate vicinity of other electronic equipment such as microwave or hi-fi units, as this can lead to mutual interference. The location has a deciding influence on the trouble-free operation of the telephone. Stand the telephone on a flat, non-slip surface. The telephone feet do not normally leave any marks on the surface. However, due to the multitude of varnishes and surface finishes used, surface marks caused by the feet of the unit cannot be ruled out.

Do not use the telephone in areas where there is a risk of explosion.

Excessive exposure to smoke, dust, vibrations, chemicals, moisture, heat, or direct rays of the sun must be avoided.

Disposal

If the useful life of the battery or the complete equipment has expired, please dispose of these carefully in accordance with statutory requirements and in a manner friendly to the environment.

Temperature and ambient conditions

The AUDIOLINE TEL28 is designed for use in protected rooms with a temperature range of -10 °C to 50 °C. The unit must not be installed in damp rooms such as a bathroom or laundry room. Avoid proximity to sources of heat such as radiators and do not expose the unit to direct sunlight.

Cleaning and care

The surface of the case can be cleaned with a dry, soft, lint-free cloth. Never use cleaning agents, particularly aggressive solvents. Apart from occasional cleaning of the case, no other care is necessary. The rubber feet of the base station are not resistant to all cleaning agents. The manufacturer can therefore not be held responsible for possible damage to furniture or the like.

3 Commissioning

3.1 Safety information

NOTE! Before commissioning, it is essential that you read the general information at the beginning of this manual.

3.2 Check contents of pack

The following items are supplied:

one telephone base one telephone receiver

one telephone connection cable one spiral cable

one desk adapter one Operating Manual

one battery type AAA

3.3 Fitting the battery

Before connecting your new telephone to the telephone network, the battery should be fitted. Please always use a type AAA alkaline battery. The battery is required for the display, the handsfree feature and other functions of the telephone. Before installing or changing the battery, make sure that the telephone is not connected to the telephone network.

Note: No messages will be shown in the display if a battery is not fitted.

1. Make sure that the telephone is not connected to the telephone network.
2. The battery compartment is to be found on the underside of your telephone.
3. Open the battery compartment with a small screwdriver or a pointed object.
4. Insert the battery, ensuring that the polarity is correct.
5. Close the battery compartment.

The battery should be changed when the display can no longer be read properly. If the battery is completely discharged, then you could lose stored telephone numbers.

3.4 Connecting the telephone receiver

After unpacking your telephone, you must first connect the telephone receiver to the base unit. First take the short end of the spiral cable and plug it into the socket at the bottom of the receiver. Turn the telephone over and plug the long end of the spiral cable into the socket marked . Feed the cable through the cable channel to the outside.

- Commissioning -

3.5 Connecting the telephone

Connect the telephone cable supplied to the telephone socket and the telephone jack on the underside of the telephone. Then feed the cable out of the telephone housing either upwards or downwards through the cable guide. Clip the cable firmly in the cable channel. The AUDIOLINE 28 telephone works using the tone dialling system.

3.6 Fitting the desk support

If you intend to use your telephone on a desk, then the desk support supplied must be fitted. To do this, turn the telephone over. Now insert the two upper hooks into the openings provided and push the desk support firmly home.

If you ever need to remove the support, press gently on the middle clips on the upper edge and then pull the desk support off.

In the receiver rest there is a small hanging device, which is used when the telephone is wall mounted. This hanging device is not required when the telephone is used on a desk, as it impedes the lifting of the receiver. Using a small screwdriver, turn this hanging device until the screw is completely flush and its upper end does not protrude at all.

3.7 Private exchanges - Setting up for T-NET

You can use the “R” signal button on your telephone on private exchanges and when using DEUTSCHE TELEKOM’s T-Net functions. If you use neither a private exchange or the T-NET-functions of the DEUTSCHE TELEKOM, no adjustments must be made here.

Private exchanges

If you have connected your telephone to a private exchange, you can use all the facilities such as call transfer, automatic recall, etc. The “R” signal button gives you access to these facilities. The FLASH time “100ms” (factory setting) will be required on a private exchange. To make this setting, move the slide switch on the underside to the “100ms” position. You can find out from the dealer from whom the equipment was purchased whether your telephone will work on your private exchange without any problems and which other facilities you will have access to.

T-NET functions

Your telephone supports the most important DEUTSCHE TELEKOM added value services (e.g. brokering, call waiting, three-way conferencing, etc.). Please contact DEUTSCHE TELEKOM to gain access to these functions (some of which are subject to charge). When using T-NET functions, move the slide switch on the underside to the “300ms” position.

- Commissioning -

3.8 Wall mounting

Your telephone is also suitable for wall mounting. Use two screws for fixing. Drill two holes horizontally side by side, 70 mm apart, and leave the screws protruding from the wall by 5mm. Now place the telephone without the desk support over the screws and push it slightly downwards.

There is a small hanging device in the receiver rest to prevent the receiver from falling when it is placed on the rest with the telephone mounted on the wall. Using a small screwdriver, turn this hanging device until a small hook appears at the upper end.

If you are using the telephone fitted to the wall, you can hang the receiver on the telephone without hanging up. You will find a small hook for this purpose at the upper end of the receiver rest.

3.9 Setting the time

If you want to reset the time or change a time already entered, proceed as follows:

1. Press the SET button. The hours display will flash.
2. Press the button several times or keep the button pressed until the correct number of hours appears in the display.
3. Press the SET button again. The minutes display will flash.
4. Press the button several times or keep the button pressed until the correct number of minutes appears in the display.
5. The current time of day is started by pressing the SET button, whereby the seconds display automatically jumps to "00".

Note: If the battery is completely discharged, it will be necessary to re-enter the time of day.

6 Using T-NET / Private exchanges

You can use the "R" signal button on your telephone on private exchanges and when using DEUTSCHE TELEKOM's T-Net functions.

6.1 "R" Button on private exchanges

If you have connected your telephone to a private exchange, you can use all the facilities such as call transfer, automatic recall, etc. The “R” signal button gives you access to these facilities. The FLASH time “100ms” will be required on a private exchange. For this purpose, set the “FLASH” switch to the “100ms” setting. You can find out from the dealer from whom the equipment was purchased whether your telephone will work on your private exchange without any problems and what further facilities you will receive from this.

6.2 "R" Button and the DEUTSCHE TELEKOM T-NET functions

Your telephone supports the most important DEUTSCHE TELEKOM added value functions (e.g. brokering, call waiting, three-way conference, etc.). The T-NET works using the "FLASH 300ms" setting. For this purpose, set the "FLASH" switch to the "300ms" setting. Please contact DEUTSCHE TELEKOM to gain access to the T-NET functions (some of which are subject to charge).

6.3 Dialling and storing telephone numbers when using on private exchanges

Note! The pause function between the code for the outside line (usually 0 or 9) and the dialling tone described in this chapter is only necessary on older private exchanges.

With some private exchanges, there is a short pause between the code for the outside line (usually 0 or 9) and the dialling tone. This pause can be entered when dialling manually and when dialling from the phone book so that the following numbers are not dialled too quickly.

Entering the pause when dialling manually

Press the redial button Ⓞ once between the code for the outside line and the actual telephone number. After an outside line has been obtained, your telephone will wait for 3 seconds before dialling the actual telephone number.

Storing the pause with the number

Simply press the redial button ⚙ after the code for the outside line and before the actual telephone number when storing the number. When dialling from the phone book, a pause of three seconds will then be automatically inserted after the code for the outside line.
