Responding to Security Warnings
When your browser connects to a TB9400 for the first time, it raises a 
security warning. Normally, secure websites have a security certificate 
issued by a trusted Certification Authority. This is to foil attempts by rogue 
websites to pretend to be something they are not. The TB9400 creates a 
self-signed certificate when the reciter’s firmware is installed. Your 
browser raises a security warning because the security certificate was not 
issued by a trusted Certification Authority. The browser has a way of letting 
you override or bypass the security warning, as explained below. 
You can be confident that you are not connecting to a rogue website 
pretending to be your TB9400, so follow the procedure below to tell the 
browser that the security certificate is OK. The browser then stores the 
security certificate and will not raise a warning on subsequent connections, 
unless the IP address of the TB9400 changes. For more information, refer 
to 
for “security certificate” in your browser’s Help.
