How does the Audio work on X1, X2 and FRS MultiSport units?
The Audio automatically cuts out when you talk or someone else transmit on your channel. The Audio automatically comes back when you are finished talking. Walkman radios work well along with all newer MP3/CD players. Some MP3/CD players will often pick up engine noise/frequency, often happen motorcycle battery don’t have good ground to the bike frame. To Avoid it try to locate your music player in different spot on you or on your motorcycle. If you are into motorcycle electrical system stuff, we found a non-profit motorcycle site. The author share a lot useful information about motorcycle repair/adjustment. http://www.cyclemaintenance.com/elec/electrical.htm Change the location of your MP3/stereo player, in a lot of cases that will take care of it. You might also get engine noise if you plug both your chatterbox and MP3 player into the 12 Volt power on your bike. Unplug one of them, the noise will go away. Also not all MP3 players are susceptible to this.
