1 General Information
Please read these operating instructions carefully. If you should have any questions, please contact our Service Department on the Hotline number 0180 5 00 13 88 (Telekom cost at the time of printing 12 cents/min). Under no circumstances open the unit yourself and do not try to carry out your own repairs. For any claims under the warranty, please refer to your dealer.
Intended use - This telephone has been designed for use on an analogue telephone line (PSTN) within Germany. However, no guarantee can be accepted for trouble-free operation on all telecommunications terminal equipment connections due to the differences between the different telecommunications network operators. The telephone requires a TAE socket with F/N coding in common with other plug-in units such as fax machines, answering machines or modems. Connect the telephone cable to the phone socket intended for the purpose only. Do not change the plug on the connecting cable.
Power failure - If the power should fail, it will not be possible to make calls using the telephone. Keep a cord-connected phone handy, which works without an external power supply, for possible emergencies.
Standard rechargeable batteries - do not use any other rechargeable batteries or battery packs. These could possibly cause a short circuit. When changing batteries, always use standard batteries, Type AAA 1.2V 650mA. Do not throw standard batteries into the fire or immerse in water. Do not dispose of old or defective standard batteries with the normal household waste.
The maximum standby and talk times quoted are applicable for the standard rechargeable batteries supplied under optimum conditions. Ambient temperature, charging cycle and other external factors, such as the radio loading in the area of use, can considerably reduce the operating times. Furthermore, the charging capacity is reduced for technical reasons during use or when stored at very high or low temperatures.
Charging the handset - It is normal for the handset to become warm when charging and is not dangerous. Do not use other manufacturer's charging equipment for charging the handset, as otherwise damage could occur.
Private exchanges - The telephone can also be connected to a private exchange. 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. Due to the large number of different private exchanges, it is not possible to guarantee this function.
Power supply - Use only the AUDIOLINE plug-in power supply provided, as other power supplies could damage the telephone. There is a risk to life if the power supply is opened and not disconnected from the mains.
- General information -
Position - There must be a 230 Volt mains socket near to where the telephone is positioned. Do not set up the base station in the immediate vicinity of other electrical equipment such as microwaves or hi-fi systems, as this may result in mutual interference. The location has a decisive influence on the trouble-free operation of the telephone.
Place the base station on a flat and non-slip surface. The feet of the base station do not normally leave any marks on the surface. However, due to the large number of varnishes and surfaces in use, it may not be possible to prevent marks occurring on the surface due to the feet of the unit.
Do not use the handset in areas where there is a risk of explosion.
Excessive exposure to smoke, dust, vibrations, chemicals, moisture, heat or the direct rays of the sun must be avoided.
Information regarding medical equipment - The telephone works with a very low transmission power. This low transmission power prevents any risk to health according to the current state of research and technology. However, it has been shown that portable telephones can interfere with medical equipment when switched on. Therefore, please maintain a distance of at least one metre from medical equipment.
Disposal - If the useful life of the standard batteries or the complete equipment has expired, please dispose of these carefully in accordance with the statutory requirements and in a manner friendly to the environment.
Temperature and Ambient Conditions - The telephone is designed for use in protected rooms with a temperature range of 10 °C to 30 °C. The base station 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 soft, dry, lint-free cloth. Never use cleaning agents, particularly aggressive solvents. No attention is necessary apart from cleaning the case occasionally. The rubber feet of the base station are not resistant to all cleaning agents. The manufacturer can therefore not accept any liability for possible damage to furniture or the like.
CE mark - The telephone complies with the basic requirements of the R&TTE Directive This is confirmed by the CE mark.

3 Setting up
3.1 Safety Information
NOTE Before setting-up, 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 base station one mains power supply |
| one handset with belt clip two standard batteries |
| one telephone connecting cable one instruction manual |
3.3 Connecting the base station
Position the base station near to your telephone connection socket and to a mains socket. Your telephone works using Touch-Tone Dialling.
- Insert the plug of the power supply into the socket on the rear of the base station and plug the power supply into a properly installed 230 V mains socket. The plug-in power supply for the base station must always be connected. For safety reasons, use only the plug-in mains power supply provided.
- Connect the telephone cable supplied to the telephone socket and the telephone jack on the rear of the base station. Use only the new telephone cable provided.
- If required, clamp the two cables in the cable channel underneath the foot support and then run these through the two openings towards the rear.
Note: The two plugs must audibly click into place so that they do not fall out again.
- Setting up -
3.4 Fitting standard batteries
To fit the standard rechargeable batteries supplied into the handset, press on the upper edge of the battery compartment and slide it downwards. Now insert the batteries taking care to ensure that the polarity is correct. Close the battery compartment cover.

natural_image
Diagram of two batteries with positive and negative charge indicators, no text or symbols presentImportant note: Place the handset in the base station with the display to the front for at least 16 hours. The telephone may malfunction if the batteries are not properly charged. The charging light on the base station will come on.
3.5 Charging the standard batteries
The standard rechargeable batteries for the handset have a stand-by time of max. 144 hours at room temperature and a maximum talk time of 12 hours. To charge the batteries, place the handset in the base station with the display to the front.
Note: Switching off the display lighting has a positive effect on the standby time and the maximum talk time. You can find out how to switch off the display lighting in Chapter 8.11.
The current battery capacity is shown in the display.
Full | Half full | Discharged. |
Note: Exactly like your car battery, the standard rechargeable batteries are unavoidably subject to a certain ageing. However, you can have an influence on this ageing process by "training" the standard batteries to a certain extent. In regular use of the phone, if you cyclically charge and fully discharge the standard batteries by using the telephone until the symbol flashes in the display, a demand is placed on the batteries and they will repay you by giving maximum performance and a long life. Extended charging and extended discharging on the other hand will both degrade the capacity and shorten the life of the standard batteries.

Using caller display, you can see with incoming calls who is calling you. If this function is available on your telephone, the display will show you the caller's telephone number when the telephone rings. If this number has already been saved in the phone book, the name of the caller will be displayed directly.
If the message PRIVATE appears instead of a phone number, the call is one where the caller has suppressed the transmission of the phone number. If the message XXXX appears, the phone number cannot be displayed for technical reasons.
All calls are stored in a caller list so that you will not miss any calls even in your absence. A total of 20 phone numbers can be stored in the list. When the list is full, the oldest number is always deleted from the list.
If new numbers are stored in the list during your absence, the display will show the

symbol.

NOTE
Caller display is an optional service from your telephone provider. Your telephone will show the number in the display if your telephone provider offers this service. The display of date and time is not transmitted by all telephone service providers. Please ask your telephone provider for further information. Furthermore, transmission of the phone number is not possible with many private exchanges.

7 Private exchanges/T-NET
You can use the "R" signal button on your telephone on private exchanges and when using DEUTSCHE TELEKOM's T-Net functions.
7.1 "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 (Adjustment, see 8.7). 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.
7.2 "R" Button and the DEUTSCHE TELEKOM T-Net
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. (Adjustment, see 8.7). Please contact DEUTSCHE TELEKOM to gain access to T-Net functions.
7.3 Inserting an automatic pause
With some private exchanges, it is necessary to dial a certain number (e.g. "9" or "0") in order, after a short pause, to obtain a dialling tone for an outside line on the extension.
An automatic dialling pause of ca. 3 seconds can be incorporated into the number.
When entering the number, hold the button pressed at the required point until the d indicator appears in the display. Then enter the remaining digits of the phone number. You can, of course, also store this pause with numbers in the phone book.

8.4 Automatic dialling code
Your telephone has an automatic dialling code function. With this function, when dialling a particular phone number, a previously stored number is inserted in front of the actual phone number.
In this way, when dialling a particular dialling code for example, you can automatically insert a required call-by-call number in front of this phone number. Or, you can automatically add the required country code to an international number.
- Special functions -
Example: The number 0221 (in this case, an area dialling code) has the number 0xxxx assigned to it. Here, the call-by-call will automatically be placed in front of every number dialled that begins with 0221. If you have dialled the number 0221-987654321, the telephone will recognise the 0221 and will dial 0xxxx-0221-987654321.
Three phone numbers, each with 5 digits, can be stored and assigned. The prefixed numbers will not be shown in the display. The phone numbers in the phone books and the caller list are also monitored.

- Multiple handsets -
9 Multiple handsets
Up to four additional handsets can be logged on to your base station.
Note: Handsets from AUDIOLINE and other manufacturers can also be integrated into the telephone system by means of the internationally adopted GAP standard. In the same way, you can use an AUDIOLINE handset on base stations from other manufacturers, as long as these units work using the GAP standard.
When you use multiple handsets you will have the following options:
- Internal calls between handsets.
- External calls can be forwarded between handsets.
- Incoming external calls are signalled on all handsets.
- Room monitoring
Note: If another handset is already using the external line, the message EXT will appear on all handsets. In this case, it is not possible to make a further external call.
9.1 Making an internal call
When you have connected multiple handsets to a base station, you will be able to make internal calls. To do this, press the ☑ button and then the number of the required handset. The call is accepted with the call button ☑ on the handset called.
If an external call comes in while you are making an internal call, you will hear short signal tones and the message EXT will flash in the display. To take the external call, end the internal call by means of the call button ⏻ and accept the external call with the call button ⏻.
9.2 Connecting external calls to another handset
If you have accepted an external call on one handset, you can forward the external call to another handset. To do this, press the INT button and then the number of the required handset. After the internal call has been accepted at the other handset, you have the following options:
A. Consultation / Brokering: You can now speak to the internal subscriber and return to the external caller by pressing the INT button. You can switch between the external and the internal call as many times as you like in this way.
B. Forward the call: The external call is forwarded to the handset called by pressing the call button ⏻ on the first handset.
- Multiple handsets -
9.3 Holding conference calls
An external call can be connected to a further internal subscriber as a conference call. In this way, two handsets can talk to the external caller simultaneously.
Establish the required connection with the external subscriber. Then press the button and the internal number of the second handset required. When the second internal subscriber has accepted the call, press and hold the INT button for 2 seconds and all three subscribers will be connected together on a conference call. The messages INT and EXT will appear in the display. The conference is ended by one of the internal participants hanging up.
9.4 Room monitoring
With the room monitoring feature, you place a handset in the required room and activate the monitor function. You can then call up this handset and listen-in to the room without the handset ringing. Also in the case of an external call, the handset concerned does not ring.

9.5.3 Logging off handsets
A handset can only be logged off using another handset that is still logged-on. It is therefore not possible to carry out the logging-off procedure using the handset that is to be logged off.

9.6 Additional base stations
You can increase the range of the handsets by using multiple base stations. In order to use this effect, all base stations must be connected to one telephone line. Depending upon how you want to use the system, you can allocate the same phone number to each base station or you can give the base stations different numbers. Make sure that the range of each base station overlaps. Please check the range of the handsets each time before setting up a new base station.
If a handset is logged on to the base station and if automatic base station selection is switched on (further information in this chapter), the handset will always be forwarded to the nearest base station automatically. Current calls cannot be transferred from one base station to another.
