Installation Error Messages

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 starting the installation
again.
Electrical interference may have caused a link to fail. Try to install
the application again.
This problem is usually associated with the unit-to-unit cable and
its connection between the handhelds. Make sure the cable is
firmly inserted in the link port of each handheld.
