The 201.581 AT20S Variable Attenuator is designed to be the only adjustment in a typical Naval Electronics AB Radio/TV Entertainment System. When sailing at sea, the
attenuator should be adjusted with its knob (center bottom above) counter clockwise for minimum attenuation. When in port and in the vacinity of strong local TV signals, the adjustment knob should be adjusted for best
picture by rotating the knob toward full attenuation, or clockwise. This attenuation does not affect the voltage going to the antenna nor does it attenuate AM-SW signals. It is normally located near the radio/TV
amplifier in the antenna coaxial cable run. Its location is indicated in the complimentary preliminary drawings we normally provide to prospective customers for their new systems in the planning stages. |
