The ZIP 560M : Direct Station Selector expansion module provides increased visibility to enhance call processing operations for users of the ZIP phones. The ZIP 560M provides 60 programmable keys with LED lamps for extensions and feature activation, and eliminates unsightly scratch-outs and changes thanks to its paperless LCD labeling system. Up to three (3) ZIP 560M modules may be connected to the ZIP 55i, ZIP 57i or ZIP 57i CT phones. Like the ZIP 536M, the ZIP 536M is powered directly from its partner phone.
