Can I use a headset with the NEC Dterm PSIII phone?
Yes. Headsets for use with the Dterm PSIII phone come in two configurations. The first is a classic banded headset with microphone extension. The second is an ear bud type with an in-line microphone. The banded headset is typically used in cases of prolonged active use (e.g. customer service agent), while the ear set is for occasional use or where concealment is desired (e.g. hotel security). Other third-party headsets may also be used, however NEC does not warrant compatibility nor guarantee quality.
