We bought a 1970 house with a 2090 system already installed. However, we need a manual to operate all the features. Is there any way to pull the instructions up on the internet? This would be a great help because one speaker is not working at all and the radio does not go thru to the front door speaker. If I set the main control on phono., I can talk and hear from outside, (front door). Please help if possible. Thelma501@yahoo.com

Are you still selling your unit? We have one in our home and need parts! We would love to get it working!
