The Wireless Telephone Headset
SpectraLink offers optional headsets for use in noisy environments
or if you need to have your hands free while talking on the handset.
To use the headset, simply plug it into the jack on the bottom of the
handset.
While using a headset, the handset will only ring externally for
NetLink e340/h340 Wireless Telephone models. There is no
internal headset ring for these models.
The NetLink i640 Wireless Telephone does have an internal headset
ring. An incoming call will ring in the earpiece. The handset will also
ring externally.
The headsets offered by SpectraLink are specially designed to work
properly with the NetLink Wireless Telephone. We do not
recommend using other headsets.
