launch the WordPad application, you can leave this field blank. If you want to assign an ap-
plication launch key that will open a specific document in the WordPad application, you
need to browse to and choose that document while the cursor is in the Data field.

5.6.2 Certificates
A public key is transmitted as part of a certificate. The certificates listed in the Certificates
tabs ensure that the submitted public key is, in fact, the public key that belongs to the sub-
mitter. The 7545 checks that the certificate has been digitally signed by a certification
authority that the 7545 explicitly trusts. This option is used in conjunction with 802.1x au-
thentication to enhance 7545 security.
