GETTING ASSISTANCE RUNNING THE SYSTEM TEST The System Test display screen is accessed through the Assistance menu and allows you to initiate diagnostic procedures on the DIRECTV System, if you subscribe to DIRECTV. You should use this feature to get your access card number or when your television doesn't seem to be receiving satellite signals correctly. A message screen appears when you select System Test from the Assistance menu. This message tells you whether the system passed each test. If your system fails the test, run the system test several times before concluding that there is a problem. Occasional fluctuations in the phone line or satellite signal can give temporary false readings. Note that if you do not subscribe to DIRECTV® programming or do not have your satellite dish antenna installed, the test will fail. ACQUIRING OFF-AIR GUIDES If you have trouble tuning to known off-air TV channels, try to select "Do Not Acquire Off-Air Guides" mode. UPGRADES Your digital satellite receiver is able to receive upgrades or modifications to some of its features and functions. These modifications will occur automatically (usually at times when most viewers are not watching programming). When an upgrade or modification is sent, you may experience a disruption in reception for a few minutes. Your reception should return to normal after the modification is complete. Your receiver must be plugged in to receive upgrades. Do not unplug your receiver while an upgrade is in progress. Please consult the Upgrade menu to find a schedule of upgrades or modifications planned by DIRECTV. 85
