Installation Error Messages

Low Battery

Do not attempt to download a Flash application if the low-battery
message appears on the home screen. Low battery indication is
shown on the initial screen. If you receive this error during an
installation, change the batteries before trying again.

Invalid Signature or Certificate

Either this device does not have a certificate to run the
application, or electrical interference caused the link to fail. Try to
install the application again.

Error in Xmit

This problem is usually associated with the device-to-device
cable and its connection between the devices. Make sure the
cable is firmly inserted in the link port of each device.
