Wipe the system with a damp cloth occa- sionally to keep it looking new. Do not use harsh chemicals, cleaning solvents, or strong detergents to clean the system.
Modifying or tampering with the system’s internal com- ponents can cause a malfunction and might invalidate its warranty and void your FCC authorization to operate it. If your system is not performing as it should, take it to your local RadioShack store for assistance.
INTERCOM SYSTEMS
Intercom systems which send voice signals over existing electrical wiring may interfere with the ability to control other modules from your control center when the inter- com is in use. If the intercom system has its own sepa- rate wiring, it will not cause a problem. Intercoms will not interfere with the ability to control the control center from the remote control.
