Scope: New revisions of the Emergency Button, Main O-Ring Seal, and Control Top Seal are available in place of the existing seals. The new seals may be used if the customer has a history of water intrusion problems or if a radio is being serviced for any other reason. It is not necessary to open a customer's radio for this replacement alone.

Implications: The product team has made various enhancements to our products as part of their endeavor to constantly improve the durability and performance of our radios in the field. Products manufactured 8/95 or later have the new seals implemented as part of a running change. Certain environments may benefit from this enhancement, and therefore may choose to incorporate these changes into their existing radios.
