Why am I unable to access the 
SMTP server?1Check with your MIS or network 
administrator whether the SMTP server 
function is open for the projector and the IP 
assigned to the projector is allowed to access 
the SMTP server. The projector’s SMTP 
socket port number is 25, this cannot be 
changed.
2Check if the outgoing SMTP server, user 
name, and password are set correctly.
3Some SMTP servers will check whether the 
mail address of From correlates with the 
User name and Password. For example, 
you use [email protected]
 as the mail address in 
From. You should also use [email protected]
 
account information for the User name and 
the password to log in the SMTP server.
Why am I unable to receive the 
test alert email even though the 
projector already indicates the 
test mail is already sent?It could be because the SMTP server 
recognized the alert mail as a spam mail or 
because of the SMTP server restriction. Check 
with your MIS or network administrator for 
the SMTP server’s setting.
