Calls Log (Caller ID)  
Reviewing Caller ID from the Handset

information for that call as new. However, the  
other registered Handset and Base displays will

and with Technical Requirements for Connection of Equipment to the Telephone  
Network adopted by the Administrative Council forTerminal Attachments (ACTA).We  
are required to provide you with the following information.  
1. Product identifier and REN information  
The label on the back or bottom of this equipment contains, among other things,

and a colon (:), and the REN is encoded in the product identifier without a  
decimal point as the sixth and seventh characters following the colon. For  
example, the product identifier US:AAAEQ03T123XYZ would indicate an REN of 0.3.  
The REN is used to determine how many devices you may connect to your  
telephone line and still have them ring when you are called. In most, but not all  
areas, the sum of all RENs should be five (5.0) or less.You may want to contact  
your local telephone company for more information.
