Your camera and monitor might cause interference on other 
radio/TV devices even when they are operating properly. To 
determine whether your camera or monitor is causing the 
interference, turn them both off. If the interference goes 
away, your surveillance system is causing it. Try to 
eliminate the interference by:
• Moving your camera or monitor away from the other 
device.
• Connecting your camera or monitor to an outlet that is 
on a different electrical circuit from the other device.
• Contacting your local RadioShack store for help.
