POWER REQUIREMENTS
The Receiver is shipped ready to operate directly on 105-130
volt, 47-63 Hz ac current. Power is applied to the Receiver by
plugging its power cord into an ac outlet. Provision is made for
operation from a 230-volt source by repositioning switch Sl loca­
ted on power supply board N0724 in the Model lSOOB.
2.3 MOUNTING
