This guide covers modifications that need to be made so an LE Series substation can be added to an existing MP-S answering station.
This station is discontinued and may no longer be supported. These instructions are provided to assist with operation and maintenance, and to guide upgrade paths.
Note: Stainless steel LE Series stations such as the LE-SSR, LE-SS/A, and LE-SS-1G do not require this mod.
