Questions about this item

How much power does the infrared transmitter draw when the NEXUS NX4203P is used continuously all day?

The remote runs on two AAA batteries and only draws power when a button is pressed, so daily use has negligible drain.

What must the buyer already own for the NEXUS NX4203P to control their device?

You need the original NEXUS component with model number NX4203P or EN21645 that this remote is designed to replace.

Will the NEXUS NX4203P work alongside an older NEXUS remote kept as a backup?

Yes, both remotes use the same infrared codes, so either one can operate the NX4203P or EN21645 unit without interference.
