1 General information
Rechargeable batteries
Do not use any other rechargeable batteries or battery packs. These could possibly cause a short circuit.
When changing, always use type AAA 1.2 Volt NiMH, 550 mAh rechargeable batteries.
Do not throw batteries in the fire or immerse them in water. Do not dispose of old or defective batteries with normal domestic waste.
If the handset becomes warm when charging, this is quite normal and no cause for alarm.
Only charge the handset on the base station. The use of other chargers may cause lasting damage.
Use only the AUDIOLINE transformer plug supplied, other transformer plugs can destroy your telephone.
Location of the base station
The base station and charger must be located within reach of a 230Volt supply socket. To avoid
interference problems, do not place the base station and charger in the immediate proximity of other electronic equipment such as a microwave oven or hi-fi system.
The location of the base station and charger can significantly influence the proper function of the telephone.
Place the base station on a level, non-slip surface. The feet of the base station will not normally mark the surface on which it stands. However, the wide range of surface finishes in use renders it impossible to exclude marking of any surface.
Do not use the handset in areas where there is a danger of explosion.
Avoid excessive exposure to smoke, dust, vibration, chemicals, humidity, high temperature or direct sunlight.
Medical notice
The telephone works with very low transmitted power. Present knowledge and research indicate that, at this low power level, there is no possible danger to health. It has, however, been shown that portable telephones, when switched on, can affect medical equipment. Maintain a distance of at least one metre from medical equipment.
- General Information -
Disposal
If the batteries or the complete system have reached the end of their useful life, please dispose of them in an environmentally friendly manner and as required by law.
Temperature and ambient conditions
The telephone is designed for indoor use and an operating temperature range of 10 °C to 30 °C .
The base station must not be installed in humid areas such as bath or wash rooms. Avoid proximity to sources of heat such as radiators and do not expose the unit to direct sunlight.
Cleaning and care
The outer surfaces of the unit can be cleaned with a soft, dry, lint-free cloth. Never use cleaning agents or aggressive solvents. Apart from occasionally cleaning the outer surfaces, no further care is required. The rubber feet of the base station are not resistant to all cleaning agents. The manufacturer cannot, therefore, be held responsible for damage to furniture etc.

3 Commissioning
3.1 Safety information
NOTE! Before commissioning, it is essential that you read the safety information at the beginning of this manual.
3.2 Check contents of pack
The following items are supplied:
| one base station one power supply for base station | |
| one charger one power supply for charger | |
| one handset four rechargeable batteries AAA 1.2V, 550 mAh | |
| one telephone connecting cable one base station support | |
| one Operating Manual | |
3.3 Connecting the base station
Position the base station near to your telephone socket and a mains socket. Your telephone works using the TTD dialling system (Touch Tone Dialling).
- First attach the base station support. To do this, insert one of the tabs at the side of the support into the associated opening. Then press the remaining tabs into the base station by squeezing the support together slightly from the sides and then pushing firmly onto the base station.
- Insert the power supply plug into the socket on the underside of the base station and insert the plug-in mains power supply into a properly installed 230V mains socket. The base station plug-in mains power supply must be connected at all times. For safety reasons, use only the plug-in mains power supply supplied.
- Connect the telephone cable supplied to the telephone socket and the phone jack 📋 on the underside of the base station. Use only the new telephone cable supplied.
- Feed the two cables through the side opening to the outside.
- Commissioning -
3.4 Connecting the charger
Set up the the charger for the second handset within reach of a electricity supply socket.
Insert the connector on the lead from the transformer plug in the socket on the rear side of the charger and insert the transformer plug in a 230V supply socket installed in accordance with regulations. For safety reasons, use only the transformer plug supplied.
3.5 Fitting the batteries
To fit the batteries supplied into the handset, press on the top edge of the battery compartment cover and slide it downwards. Now insert the two batteries supplied and close the battery cover.

Important information: Place the handset with the display to the front on the base and charging station for at least 16 hours. If the batteries are not correctly charged, the telephone may not work properly. While the handset is being charged, the
battery capacity symbol will flash in the display.
3.6 Charging the batteries
The rechargeable batteries in your handset have a standby time of max. 8 days at room temperature and a maximum talk time of up to 12 hours. To charge the batteries, place the handset in the base station. The current battery capacity will be shown in the display.

full

Less than 30 minutes
No display
Batteries are discharged
Note: The batteries must be charged for at least 16 hours before being used for the first time. Exactly like your car battery, the rechargeable batteries are unavoidably subject to a certain ageing. However, you can have an influence on this ageing process by “training” the batteries to a certain extent. In regular use of the phone, if you cyclically charge and fully discharge the batteries by using the telephone until
the 📁 symbol appears 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 batteries.

You can increase the range of the handsets by using two base stations. To make use of this effect, a telephone connection must be made to both base stations. Depending upon the application, you can assign the same telephone number to each base station or you can give each base station a different number. Ensure that the ranges of all base stations overlap one another. If a handset is logged onto the base stations the handset is automatically transferred to the nearest base station.
Calls in progress can not be transferred from one base station to another.
