My remote acts up at times with my X24 by not playing the sound or not muting when pushing the mute button. I can scroll through the call files and then select one and it will not play or change sounds. I have had this happen more than once. I run Energizer lithium batteries in the remote. Does the call and remote need to be next to each other when turned on, does this matter? A few times I had to go out and bring the call in closer. I hardly ever put the call out past 40yds. Thanks
