You use a pyramid-shaped remote signal sender and it doesn’t seem to be responding when you press buttons on the remote.

Possible Causes
The extender that receives the signal may not be facing the remote control.
Sunlight may be interfering with the IR signal.
The sender might have the wrong light setting.

What to Do
Reposition the extender and try again.
Block the incoming sunlight and try again.
Change the light setting and try again.
