I just got this radio and am not used to all the programing options. The manual probably has the answers I need but its not giving them up without a fight. I plan to use the radio for a ground vehicle so I need to turn off or change the throttle alarm so that when the stick is centered all is well. I just converted the throttle stick to self centering so as soon as I turn it on the alarm goes off and its getting old real fast. Any help setting this radio up would be appreciated.
