English Setting up Your Display Connecting the Antenna Connecting CATV Your DV3250 LCD Display has an internal 75 ohm coaxial cable connector, so antennal hook-up is very easy.When connecting a 75-ohm coaxial cable, secure it firmly to the antenna connector. Some cable TV companies provide "pay per view" programming. Since the signal for these paid channels is encoded, most cable TV companies provide their own tuners/ decoders. You must install a tuner/ decoder to be able to view locked encoded programming. If you require special instructions on how to install cable service, please contact your cable TV provider. The tuner/ decoder provided by your cable TV company can be used according to the following instructions. You must have an RF switch with two inputs (A and B). The "A" input on the RF switch allows you to use the display's Channel / buttons to view unlocked channels. The "B" input on the RF switch allows you to use the channel selection button on your cable box to view locked encoded programming via the tuner/decoder. Antenna The antenna equipment has far more effect on reception for color TVs than on black and white models. We suggest you use a good-quality outdoor antenna. Following are simple explanations for the connection of various types of antennas. 1. Generally speaking, 75 ohm systems have a round cable with a BNL connector which requires no tools. Attach the cable directly to the input. 2. 300 ohm systems have a flat "dual lead" type cable. A 300-75 ohm transformer may be used to attach the antenna to a 75 ohm input. Installation of an Outdoor Antenna For best reception it is recommended that an Outdoor antenna be used. A: Use a combination VHF/UHF outdoor antenna. B: Use separate VHF and/or UHF outdoor antennas.
