5.1.2  Logging On To the System
When the phone is logged on to the network, you can either use the 
phone directly, or you need to log on to the telephony system, see below.
• The phone logs on automatically to the telephony system, and the 
phone is ready to use. You cannot log on or log off. This mode can 
be used for phones in, for example, receptions.
• The phone has to be logged on manually to the telephony system 
before you can use it. You are either required to enter the extension 
number, or the extension number and a password (or PIN code).
Note:  The PIN code can be changed by the user (see 18.8.1 
Changing PIN Code on page 114), whereas the password has to 
be set by 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.
5.1.3 Free User
When log off is allowed, the phone must be logged on (registered) to the 
telephony system before you can use it. When the phone is logged off, 
the display will look like in figure 14 on page 33. If the emergency call 
function is enabled, it is possible to make emergency calls. For more 
information on emergency calls, see 8.3 Emergency Calls (SOS Calls) 
on page 54.
