This is an accessory for SC211, SC220 and SC421. It is a front cover protecting the keyboard from the mechanical force of water, when the station is used on deck where sea water can be expected. Using the front cover increases the IP rating from IP64 to IP65.
The front cover is accoustically open, which means that the SC421 can be operating in hands free even if the cover is closed.
