ConnectionsANTENNA CONNECTIONTO CABLE TV (CATV) • A 75-ohm coaxial cable connector is built into the set for easy hookup. When connecting the75-ohm coaxial cable to the set, screw the 75-ohm cable to the ANT. terminal.• Some cable TV companies offer “premium pay channels”. Since the signals of these premiumpay channels  are likely  to  be scrambled,  a cable  TV  converter/descrambler is  generallyprovided to the subscriber by the cable TV company. This converter/descrambler isnecessary to watch scrambled channels normally. (Set your TV to channel 3 or 4 as one ofthem is generally used. If the channel is unknown, consult your cable TV company.) For morespecific instructions  on installing  cable  TV, consult  your cable  TV  company. On  the nextpage, a  possible  using method  of  the converter/descrambler  provided  by your  cable  TVcompany is  explained.  Please  note:  an  RF  switch  provided  with  two  inputs  (  A  and  B  )  isrequired (not supplied).12Cable TVConverter/DescramblerTwo-set signalSPLITTERRF SwitchIncoming cable
ConnectionsTO WALL ANTENNA SOCKETIf there is  a wall  antenna socket in  apartment house,  connect    the antenna  cable as  shownbelow. (Use the type of antenna cable corresponding to that of wall antenna socket.)For good  quality  of  image,  the  antenna  requirements  of  color  television  reception  are morestrict than those of black & white television reception. Thus, it is strongly recommended to usegood outdoor antenna.The following  is a  brief explanation  of the  type of  connections that  are provided  with  thevarious antenna systems.1. A 75-ohm  system is generally  a round cable  with F-type connector that  can be easilyattached to a terminal without tools (not supplied).2. A 300-ohm  system is  a flat  “twin-lead” cable  that can  be attached  to a  75-ohm  terminalthrough a 300-75-ohm antenna converter (not supplied).• If you have a 75-ohm round cable, insert bronze wire and then tighten connecting nut. If youhave a 300-ohm flat cable, connect twisted wire to antenna converter and then connect theconverter to ANT IN.• When using 75-ohm round cable, do not bend bronze. It may cause poor picture quality.13Wall connecting port75 round cable300 flat cableAntennaconverterTurn clockwise to tighten
ConnectionsTO OUTDOOR ANTENNAThis type of antenna is usually used at common private house.• Use one of the two following diagrams if you connect an outdoor antenna. A : Using a VHF/UHF combination outdoor antenna.B : Using separate VHF and/or UHF outdoor antennas.• Connect the outdoor antenna cable lead-in to the ANT IN on the back of TV set.• In a poor signal area, you can get better picture quality if you install the antenna like thefigure “B”.• If an antenna is divided to two TV sets, use “signal divider” for connection.14CombinationVHF/UHF Antenna75 round cable300 flat cableTurn clockwise to tightenAntennaconverterSignalAmplifierUHFVHF
