The loudspeaker has a „hopping“ volume

1. The volume of the loudspeaker is automatically regulated with the line current.

If the loudspeaker volume is regulated too high, the telephone line might not have

enough power to supply the device at high volume. To avoid this reduce the

volume or try to power the device with an external power supply.

Technical support

Use the telephone number or e-Mail address on the last page of this manual for

more information.
