Handsets can be changed to desk mount with the addition of a model TZ1003 desk adaptor, or can be flush mounted with the addition of a model UM1004 flush housing/trim assembly. All HT2009/2 handsets feature textured finish (to minimize scratches and fingerprints), electric buzzer signaling (adjustable), heavy duty coiled cord with strain relief and (2) two momentary button switches.
