• 
If you subscribe to digital subscriber line (DSL) high-speed Internet 
service through your telephone line, you must install a DSL filter between 
the telephone line cord and the telephone wall jack. The filter prevents 
noise and caller ID problems caused by DSL interference. Contact your 
DSL service provider for more information about DSL filters.
•  Use only the power adapters supplied with this product.
