For releases prior to R5.0:
The MERLIN LEGEND Control Unit recognizes the MLX-5 telephone as an MLX-10:
■When an MLX-5 telephone is installed, all line and feature buttons beyond the first 5 physical buttons must be removed by the System Manager using system programming. This is important so that “phantom” buttons and lines are not inadvertently placed on the MLX-5 telephone. For example, you may have a line programmed on what would be Button 6 of an MLX-10 telephone. If it is not deleted, calls will continue to ring on this line but there will be no call appearance on the MLX-5 telephone.
■The Extension Information Report will show “MLX-10” as the “Type” for an extension with an MLX-5 telephone.
