8-21. Testing the System
ATSC Signal Test Checks the signal strength of of each off-air digital channel for a selected physical channel broadcast range*. This may be helpful to determine the best balance and antenna positioning for receiving broadcasts from different areas. To see the ATSC signal strength : 1. Press the MENU button on the remote control to display the on-screen menu. 2. Scroll down using �E� on the remote control. 3. Select the System menu by pressing � �. 4. Scroll down to System Test using �E�. 5. Move the highlight to the right with �G� to display the system test option box. 6. Scroll down to ATSC Signal Test using �E� on the remote control. 7. Press � � and the pop-up dialogue box will be displayed. 8. Select one of CH.2-CH.33/CH.34-CH.65/CH.66-CH.69 with �FG�. 9. Move the cursor to highlight the Start button and press � � to run the ATSC Signal Test. It will check each physical channel and report the signal strength of each channel. Note : While the maximum signal strength is 100, the typical signal strength will be in the range from 60 to 85. There should be no obvious change in the picture or sound quality at these levels. Should the signal fall below this range or fluctuate below this range, you may experience video macroblocking or audio dropouts, so you should adjust your antenna or dish, as needed. In general, the higher the signal, the less likely you are to experience picture quality degredation during adverse weather conditions such as heavy rain or snow. * Physical broadcast channels displayed here may not match the channel number which is chosen for displayed by the broadcaster. To confirm the physical channel, tune to the off-air digital channel and press the SIGNAL button on your remote. The physical channel number will be displayed next to the antenna icon.
