3.1.2  Logging On To the System
When the phone is logged on to the network, there are three possible 
scenarios:
• The phone is ready to use. This means that the phone logs on auto-
matically to the telephony system.
• You have to log on the phone to the telephony system with an 
extension number.
• You have to log on the phone to the telephony system with both an 
extension number and password (or PIN code).
Note:  The PIN code can be changed by the user (see 13.8.1 Changing 
PIN Code on page 102), whereas the password can only be set 
by the system administrator.
If you are required to log on the phone to the telephony system, you are 
prompted to enter your extension number, or your password (or PIN 
code), or both.
To log on to the telephony system, do the following:
1. Enter your extension number and press Log on
2. Enter the password (or PIN code), if required, and press Log on 
again.
Note:  If the extension number or password is not accepted, the 
following message is displayed: “Failed User Log on! No calls!” 
Then make a new logon attempt. Should the logon fail again, 
please contact the system administrator.
The phone does not work during power failure. After a power failure the 
phone automatically restarts. When the phone is starting up (rebooting), 
any PC that is connected to the phone will loose its network connection 
for about 10 seconds.
