Hi , 1- receiver and transmitter dont have same preset buttons os they have to be set manually. Very unpractical for clients who will try to connect in the field 2- Transmitter lcd PR13 is flikering and is unstable after 12 hours + charging Is there a solution ? 3- distance is at best 50 feet inside a building with walls. is it normal ? 4- interference of radio station is making the reception of the speaker very difficult. Thanks for your response
