details on correct operations.
Remedy
• Many digital channels have alternate channel numbers. The unit changes the
numbers automatically to the ones signifying the broadcasting stations. These are
the numbers used for analog broadcasts.
• Check the antenna or cable connection to the main unit.
• Check the batteries of the remote control.
• Check if there is an obstacle between the infrared sensor window and the remote
control.
• Test the signal output. If OK, then possible infrared sensor trouble.
(Refer to "IR Signal Check" on page 26.)
• Aim the remote control directly at the infrared sensor window on the front of the
unit.
• Reduce the distance to the unit.
• Re-insert the batteries with their polarities (+/– signs) as indicated.
Problems with Closed Caption Feature
• Closed captioning production companies may broadcast programs without
correcting the misspelling in a live broadcast.
• Captions that are delayed a few seconds behind the actual dialogue are common for
live broadcasts. Most captioning production companies can display a dialogue to a
maximum of 220 words per minute. If a dialogue exceeds that rate, selective editing is
used to insure that the captions remain up-to-date with the current TV screen dialogue.
• Interference from buildings or weather conditions may cause captioning to be
incomplete.
• Broadcasting station may shorten the program to insert advertisement. The closed
caption decoder cannot read the information of the shortened program.
• The videotape may be illegally copied, or the caption signal might not have been
read during copying.
• Text mode is selected for caption. Select "C1", "C2" or "OFF".
