Please note for the HME 45 telcom

If your telephone has a headset socket not corresponding to the 121 TR 9-5

standard of the German Telekom, you have to have an adaptor made, or you have

to use a new plug. Figure  shows the wiring arrangement.

Some telephones (especially from German manufacturers) have a receiver socket

suitable for the headset. In particular, this socket is able to supply the necessary

operating voltage for the condenser microphone.

Please ask your telephone manufacturer whether you can directly connect a

headset (fig. ). He will need the circuit diagram and the technical data of your

Sennheiser headset. Please photocopy pages 10 and 29 of these operating instructions

for him.
