The record contains a RF (radio frequency) modulator for use with the Timex Sinclair 1000. There is a sticker on the front of the adaptor. On the front in the upper left corner "Game" is printed to label the RF connector at the top of the modulator. There is a sliding switch in the center center that goes from "Game" to "TV". Printed on the right side is "Connect to TV VHF", which labels the cord extending from the right side. That cord ends in a 75 OHM twin lead. The bottom edge says, "connect to antenna". On the side below that label are two screws.
