      Hi Fred thanks for all the info.
      I am using the OT3 with a Nuvi 350 & FTM-350 for Raynet use
      my original request for settings was because I was having difficulty in getting the OT3 and FTM-350 working together this has now been resolved, it is now just a matter of getting the settings to my liking
      for smart beaconing and as you have pointed out the audio levels as well.
      many thanks Andy G0MNI
