● LEDs (see chapter Codes: Front LEDs (Page 40))
● Test e-mail:
The CP 243-1 can send a test e-mail with an HTML page that is called from a Web
browser. This mechanism makes it easy to check whether a desired e-mail server or e-
mail receiver can be reached from the CP 243-1. The user name and the password of the
administrator must be specified before this test e-mail mechanism can be triggered. The
error messages that can occur while a test e-mail is being sent are explained in chapter
Error messages of the test mechanism for e-mails (Page 117).
