Problem
An SDN button on my extension does not work.
I cannot use the secondary Ethernet port.
Remedy
•
A PDN button is not assigned on the
extension corresponding to your SDN
button.
Create a PDN button on the desired
extension. ( 3.1.3 Customising the
Buttons)
•
If you are using a KX-NT500 series
telephone, check whether ECO mode is
enabled ( Display in 1.1.5 Before
Operating the Telephones). If it is enabled, ask
your dealer to disable ECO mode. For other
types of IP-PTs, contact your dealer.
