The SatStation Standard Dock is designed to fit the needs of a fixed unit for your boat or vehicle and the flexibility to carry the portable phone when you are away. This combination provides a communication interface to link voice and data connections through a single unit. When the phone rings you can hear it loud and clear with a built in loudspeaker. The SatStation Standard Dock allows for better communications and the benefits of a fixed phone with a portable option! Since the dock is charging the portable phone, you will have a fully charged phone ready to be used either at your hotel or an extreme situation such as a distress call from your life raft.
