[. . . ] Before you call for service, perform these simple checks. Some of these symptoms can be readily corrected.

PSIP information contains data such as the channel numbers that will normally be seen by the viewer of the channel. These channels are virtual channels meaning the channel numbers displayed may not represent the channel numbers where the signals are physically located. In normal viewing of ATSC signals by consumers, these virtual channels are used when tuning. However, in some commercial applications there is a desire not to use virtual channels and instead use the physical channel numbers when tuning. the Hotel Mode Menu allows the selection of "PSIP" to either Yes or No. Setting PSIP to Yes means that the PSIP Virtual Channel Tables will be processed and used when tuning digital signals. Setting PSIP to No means PSIP Virtual Channel Tables will not be processed and digital channels will be tuned using the RF channel location and MPEG program number as defined in PAT/PMT. When installing the channels, different inputs can be mapped to TV channels to allow seamless integration into the channel map. The two sections below explain how to install analog channels and AV inputs, and how to install digital channels. SOURCE: Select the input source that you wish to associate with the specified CHANNEL. This feature enables you to "map" (re-assign) a numeric channel number to a video input, rather than to its normal RF TV channel (i.

[. . . ] The pictures you receive may be transmitted in 16:9 format (wide screen) or 4:3 format (conventional screen). 16:9 pictures sometimes have a black band at the top and bottom of the screen (letterbox format). This function allows you to optimize the picture display on screen. Using the different formats Select the preferred format from the SWITCH ON PIC FMT menu item in the setup screen, or (if applicable) use the Format button on the Remote Control to select the different modes: 4:3, Zoom 14:9, Zoom 16:9, Subtitle zoom, Super Zoom, and Widescreen.
