Standby unit for TV economy

Infra-red remotely controlled equipment is provided with a standby mode in which it remains ready to operate at a simple command of a particular button on the remote contra I unit. In this mode, older television receivers can dissipate 20 W or more! The add-on switch described in this article can bring this figure down to about 1.5 W. It is simply inserted in the cable between the mains outlet and the equipment and operated by the existing infra-red remote contral unit.
