Security Configuration; Network Configuration - Motorola 7545MBW User Manual

G - 10 Omnii Hand-Held with Windows CE 6.0 User Manual

Security Configuration

The Security Configuration dialog box is accessed through the Tools menu. The Security Configuration dialog
box allows you to enable, disable and change the PIN. You will need the current PIN to make any of these
changes. The PIN must be enabled in order to be changed. (If the PIN is disabled, the New PIN entry field is
greyed out.)
NOTE
Keep in mind that some network operators do not allow the SIM PIN to be dis-
abled. A new PIN must consist of 4 to 8 numeric digits.
The Require PIN on resume check box is independent of the aforementioned settings. By default, this check
box is unchecked. While this option remains unchecked, any PIN entered on startup or through the Security
Configuration dialog box and submitted successfully to the modem is stored in memory for as long as the
device is not rebooted. This stored PIN is then used without further user interaction whenever the modem
requires a PIN (such as resume after suspend or modem removal). The stored PIN is also automatically
entered in the Current PIN text box whenever the Security Configuration dialog box is called up.
If unauthorized access to the device is a concern, the Require PIN on resume check box should be
checked. In this case, the PIN is not stored; whenever a PIN is required, you will be prompted to enter an
appropriate value.

Network Configuration

In the main Wireless WAN window:
• Tap on the Tools menu, and choose Network.
Enable Automatic Network Select
By default the GSM radio modem automatically chooses from the available and allowed networks (allowed
networks are the home network and all other networks with which the home network has a roaming agree-
ment). You may find there are some situations in which you want to override this default behaviour. For
example, you may want to disable roaming if you find yourself in a border area where the home network is not
available but a foreign roaming partner is available. Abroad, you may find that an available network does not
have GPRS roaming agreements. In this case, you'll need to manually select the network which you know to
support GPRS roaming.
Automatic network selection is enabled or disabled by checking or unchecking Enable automatic network
select in the Network dialog box. When automatic network selection is disabled, you must select a
network manually.
