General Information

Echo Effect

In some cases, while using the telephone you may hear an echo, which can be quite strong. This is not due to any design defect or other fault with your IP telephone, but caused by the other client. For example, if the echo occurs during a teleconference, it may be that the loudspeakers and micro- phones need to be repositioned.

Service

The Siemens service department can only help you with encoun- tered problems or defects on the unit itself.

Should you have any questions regarding the operation, your spe- cialist retailer or network administrator will gladly help you with the right answers.

For any questions regarding the telephone connection, please con- tact your network provider.

In the case of any trouble or defects on the unit itself, please dial the ser- vice number of your country.
