Important information

Operation during power failure

Even in the case of a power failure, the basic telephone functions remain executable (manual
dialling and ringing signal for incoming calls, see chapter "Emergency operation").

Cleaning

Use a soft, slightly moist cloth for the housing surface. Please do not use abrasive liquids or
chemicals to clean the device. The telephone is maintenance-free.

Installation

Please take care that the cables do not lead to any danger of stumbling and avoid folding,
pushing and pressing of the cables.
Some furniture lacquers or furniture cleaning products may attack the rubber at the feet of your tiptel
telephone and thus cause patches. In such cases please use a non-slip pad under the device.
The telephone may not be installed and used in an inappropriate environment. Avoid:
- humid rooms, dusty rooms and rooms with danger of explosions
- temperatures of more than 40°C and less than 0°C
- strong vibrations
- exposure to direct sunlight

Possible malfunctions

Use the information provided in chapter "Troubleshooting" or plug another telephone at the
corresponding telephone wall socket in order to detect whether the malfunction was caused by
your tiptel telephone or not. Never open or connect a defective device. Bring the device to your
local dealer or service centre. Please keep the original packaging carton and material in case
that it will become necessary to return the device. This material will grant optimal protection while
transported. You should make a back-up of all your entries (e. g. by using the software TipKom
on a PC) in order to avoid a loss of data (only tiptel 292/293).

Ecological information

During the normal use of the telephone, you will not have any contact to substances damaging
to your health. The synthetic material and plastics used for manufacturing this device exclusively
consist of partially recycled granules. Our packaging materials do not consist of plastics but of
partially recycled cardboard and paper.
