Sony P910a Betriebsanweisung

If you make a new telephone call you can interrupt an ongoing 
GPRS session, for example, an incoming email. Select the check 
box to get a warning in such a case.

Select the check box when you want to use the P910a together 
with a TTY accessory. Teletype (TTY) accessory, text phone, is 
an aid for deaf and speech-impaired people.

Advice of Charge allows you to keep track of the cost of calls 
and to stop the P910a from making chargeable calls when a 
certain credit limit has been exceeded. The Advice of Charge 
option only appears in the list if it is supported by your current 
subscription.

If the credit is limited, a 

 warning is displayed, when 

there is approximately thirty seconds of credit left. When the 
credit runs out, 

 is displayed and ongoing, 

chargeable calls are stopped.

Please refer to the Help system for detailed information about 
the Call meter settings.

Note PIN2 is required from your network operator for storing 
any changes you make to the Call meter settings.

Not all networks provide charging information to the phone 
during a call. If your network provides this service and your 
subscription is for Advice of Charge Charging, you cannot make 
or receive any chargeable calls if you are roaming in a network 
that does not provide charging information.

Use Alternate Line Service to make calls on two lines with 
separate phone numbers. Some of the phone settings are used on 
a per line basis. In most cases, the settings displayed apply to the 
selected line. This is then indicated in the dialog title bar. In 
other cases, the lines correspond to separate settings or tabs in 
the dialogs.

1. Select the 

 dialog.

2. Edit the names for line 1 and 2.
