If required, face plate gaskets are provided to further eliminate water infiltration. All connections are hand soldered to eliminate corrosion, and the connections at the push button switch and microphone are also hand sealed using a special non-corrosive electronics grade flexible silicone sealant. The entire circuit board is "potted" in a flexible urethane encapsulating material, leaving the weather sealed field-adjustable trim pots and DIP switches accessible for on-site programming. The flexible urethane sealant allows the circuit board and its components to expand and contract, while maintaining weather resistance. To protect the tip and ring connections, special connectors filled with anti-corrosive sealing gel are included.
