I have two DCS handheld remotes which are about 4 years old. Both have been updated to 4.1. One works very well and has no problems. However the other one has a hard time communicating with the TIU and I keep getting out of range messages, or engine not on track. When I get these readings/messages I immediately pick up the other remote and everything work great. I have put new batteries in the unit which has not helped. I have both remotes programmed with the same engines in the same order. Any thought on next steps I should try?
