This switch (or button) is used to select the type of tuner reception. To receive VHF and UHF TV broadcast stations set the switch to NORMAL. To receive unscrambled cable programs set it to CATV. A decoder is required to receive pay-for-view. Note: VHF and UHF channels and CABLE channels with the same number cannot be programmed into the tuner memory at the same locations. ©Misterßetamax go to homepage
