When poweringby a battery use a PIK170 power injector to maintain short circuit protection.3

TECHNICAL ADVICE1. Check there is no earth braid touching the centreconductor on the coaxial cable.2. Is there more than one outlet? Check thesplitter box, the power supply must be connectedto the coaxial outlet that feeds the AC/DC leg ofthe splitter box to pass power to the head unit.3. Is there now too much signal causing anoverload effect to the VCR? Try turning downthe gain controls on the masthead unit, or select asmaller dB rating amplifier.If there is a white line moving through thepicture: Try a PSK06 14 V DC power supply.4Part No: 310133Drawing Number: 40737-3
