handset. When the handset is being used, operating the Handsfree key
switches the speech path to the speakerphone.
Note: The Plantronics Supra (Model MH0530-1), ACS Ultralight with
intra-concha earpiece (Model NWMP), and the Plantronics Starset
(Model MH0230-1) are headsets which are compatible with either the
M5317T telephone.

This feature provides independent adjustment for the speakerphone, alerting
tones, and the headset and handset. Volume settings are retained during
power failure.

during power failure.

NI-1 and Meridian 1 modes only. This feature permits the user, whenever
applicable, to edit displayed numbers before completing an operation (for
