❍ Headsets that have open style receivers (i.e., Mirage,
Duoset and Duopro) can cause echo problems on
DT700 Series telephones. The echo suppression and
receiver gain of the telephone determines the severity of
the echo when using any headset.
❍ Due to the environment where the telephones or
headsets are located, ambient noise may affect
performance. Please contact NEC for the recommended
headset to use with VoIP applications.
