Monterey The remote control works fine some of the time, but at other times, it will barely work at all. Or it works fine if you are in front of the receiver, but won't work from other rooms very well. The problem is usually caused by UHF interference. The Monterey remotes send out Infra Red signals that are picked up by the remote eye in the front panel. But they also send out a UHF signal that is picked up by the 6 inch whip antenna that is attached to the UHF Antenna Module, which is plugged into the back of the receiver.
Any electronic equipment can emit interfering signals.
Even the Monterey itself can interfere with the UHF module if it is close enough to it. Most often the solution to this problem is to move the antenna module as high up in the air and as far away from any electronic equipment as possible. The cable that comes with the module is 6 feet long. Occasionally it may be necessary to use an extension cable. Certain keys on remote don't work well.
