The 50R Mesh 2.0 Intercom couples Sena’s most advanced technology to date with a low-profile, sleek yet rugged design. We do have the Sena 50S as well and thought this is a good companion for it as both have the Mesh 2.0
Please, check the manual: www.sena.com/document.aspx?doc=UsersGuide_50R_1.2.0_en_200910 The scratch sticker is to use if you could not setup your Intercom with the sliding plan. You need to use the sticker without scratch on the sliding plan.
