Adding and removing certificates

Your P800 handles certificates automatically so, most of the time, you can browse the Internet securely without using Certificate manager. If you do need to add or remove a certificate, you will usually be informed by your network operator or system administrator. You should remove a certificate from Certificate manager if you are informed, or suspect, that:

The certificate does not belong to the person who supplied it.

The certificate was issued incorrectly by the independent organization that created it.

Display

Use the Display settings to control the screen and power functions of your P800.

Wallpaper

You can set a picture to be the background for the standby screen. Select Browse from the drop-down list to see picture files available on your P800. Read more about background pictures in “Personalizing your P800” on page 134.

Type of certificate

The type can be either Certificate Authority or User.

Certificate Authority certificates contain server details. This type of certificate is handled by your P800 when the server only requires server authentication. This means that your identity remains anonymous.

User certificates contain your identity. This type of certificate is used when the server asks for client authentication. The client application requests you to identify yourself by choosing a user certificate.

Screen saver

You can set a screen saver picture to be displayed after a period of inactivity. You can also turn this facility on and off and select a delay period of up to 15 minutes before the screen saver is displayed. Read more about screensaver images in “Personalizing your P800” on page 134.

If you select the Screen saver device lock check box the device lock will activate when the delay runs out. Read more about Device lock in “Device lock” on page 41.

Power save

You can set a power saver to switch off the screen after a period of inactivity (2, 3, 5, 7, 10, 15, or 30 minutes). When the power saver activates, the screen will be switched off. Touching the screen or pressing a key switches the screen on again.
