Comdial strives to design the features in our communications systems to be fully interactive with one another. However, this is not always possible, as the combinations of accessories and features are too varied and extensive to insure total feature compatibility. Accord- ingly, some features identified in this publication will not operate if some other feature is activated.

Comdial disclaims all liability relating to feature non-compatibility or associated in any way with problems which may be encountered by incompatible features. Notwithstanding, anything contained in this publication to the contrary, Comdial makes no representation herein as to the compatibility of features.
