This is the only remote I have ever used that when you press Volume or Channel it does not continuously change...the volume changes only one step and you must press again. You must press for each channel! This is not the way remotes should work.Further, the codes for the Pioneer Amplifier did not work correctly. They can be re-programmed.I sent this back. If a remote cannot transmit multiple times when a button is held down, it is worthless to me.
