Hi there Chris and welcome
Are you using the original remote from the unit? Or is it a universal remote?
ok, it means they have used the same IR code for both models for this.
Unfortunately the only way to resolve this will be to movie the devices to an angle where when aiming at one device the other device does not see this.
You cannot change the IR code the device receives (this is hard coded into the unit).
So you would need to ensure that they do not see the signal at the same time sorry.
ok, but you cannot change the IR code on the unit, so there is no way to change this sorry.
They are both using the same codes, and you cannot reprogram it to a new one
ok, can I ask though Chris, considering the situation and what I have told you what you wish for then?
ok, you need to contact customer service for a refund
