Does the DIS-CCU central control unit ship with Chairman and Interpreter button overlays for the DC 5980 P portable discussion unit, like the CU 5905 central unit did?
No. The DIS-CCU may be used with a variety of 5900-series and 6000-series conference units that each use different button configurations. The Chairman and Interpreter button overlays for the DC 5980 P discussion unit are sold separately as model DC5980P-ACC-CM-IS, which includes 2 Chairman overlays and 3 Interpreter overlays. Delegate button overlays are still included with each DC 5980 P.
