Have had 3 of these for awhile. use them just to scan never powered on more than 2 hours mostly on the weekend.
one of them the past few months has trouble seeing the remote. needing re-booted or just wait keep pushing the buttons in frustration. reset it about a month ago that worked for awhile ... but now nothing

These come with 2 remotes I've mostly/always used the smaller one. the other bigger remote doesn't help now.
how would one make the change ?

Thanks for reading
