My device is not using the correct ring tone or Home screen background If you are using a ring tone or Home screen background picture that you encrypted on your media card using your BlackBerry® device password and you reset your device, unlock your device. Map troubleshooting Diagonal lines appear on a map Diagonal lines appear on a map when your BlackBerry® device loads a new map or when your device is not connected to the wireless network. If diagonal lines appear for a long period of time, verify that your device is connected to the wireless network. Contact troubleshooting Custom address book field data is not appearing on my computer You can only synchronize the data in a custom address book field with a text field in the email application on your computer. For example, you cannot add a contact's birthday to a custom address book field on your BlackBerry® device and synchronize it with the email application on your computer, because the birthday field is a date field in the email application on your computer. Calendar troubleshooting I cannot schedule appointments that span multiple days If you use IBM® Lotus Notes®, you cannot schedule appointments that span multiple days. I cannot set some fields when scheduling appointments If you use IBM® Lotus Notes®, you can only change the Subject, Location, Reminder, and Notes fields and the Mark as Private check box when you change a recurring appointment or meeting. Some characters in calendar entries do not appear correctly after synchronization If you schedule appointments or meetings on your BlackBerry® device that contain special characters or accents, your computer might not support these characters. On your computer, verify that you are using the correct default code page and that the correct font support is installed on your computer. See the documentation for the operating system on your computer for more information. 250
