Troubleshooting

Operation problems can be due to a variety of causes. The first step in solving them is to make
sure that all cables are securely attached and seated completely in their sockets. In addition,
updating the product's firmware may solve problems that have been discovered and resolved
since the prior version was released. If your product is not running the latest firmware version,
we strongly recommend that you upgrade. See the Firmware Upgrade Utility for details
