Congratulations on your new purchase!
Before using this user guide please read the following important information:-
• Call Blocker protects a single corded phone, or a cordless phone with additional handsets
• Caller Identity service (Caller ID) from your telephone provider is required for Call Blocker
to work effectively.
• Caller ID is telephone service that provides for subscribers the telephone number of a
caller, which appear on a display as the call is being received. It is available from most
telephone companies. To register for Caller ID contact your telephone operator - Caller ID is
available free with BT and most other providers, just dial 150 to find out.
• The CPR Call Blocker will work with a wide range of telephone equipment including corded
and cordless phones. It protects all the phones that are plugged into it. If you need a
number of extensions in your house we recommend that you use a modern multi-handset
cordless phone system (Also known as a DECT system) so that the CPR Call Blocker can then
protect all your phones.
• We recommend that you do not use the CPR Call Blocker with phones plugged into other
extension sockets in your house. This might cause other phones to ring once if a blocked
number is calling.
• Some phones automatically check the 1571 network voicemail service at regular intervals
and display a ‘Message waiting’ light. These are called 1571 phones. We recommend that you
do not use 1571 phones with The CPR Call Blocker
