Manufacturer's product description

The BT4000 Big Button has lots of features that make using the phone easier.
• Compatible with hearing aids
• Inductive coupler – works with many hearing aids (when they’re on the ‘T’ setting) to actively reduce background noise
• Easy to grip handset
• Large, well-spaced buttons with good colour contrast
• Choose what kind of incoming calls you want to block (international, withheld, not available and payphone) and block up to ten specific numbers
• Store up to 50 names and numbers in the phonebook
• See who’s calling you: if you’ve got a caller display service and your caller's number is stored in the phonebook, their name will be shown on the screen
• Easy-to-read screen (1.8” amber backlit) with a large font
• Flashing light shows you when someone’s left you a 1571 message
• Hands-free capability
• Amplify incoming sound volume
• Socket for plugging in a headset

To block nuisance calls and see who’s calling, you’ll need a caller display service from your network provider (which you may be charged for). You may also be charged for using the 1571 service.
