trols are shown in the photo above.
NORMAL RADIO OPERATION
Knob "A" on the clock turns the radio on or off.

A built-in loop antenna eliminates the need for an out¬

tion, rotate the receiver slightly for best signal strength.
If additional pick-up is necessary, connect an external an¬
tenna to the radio by following the instructions printed on
the rear panel.

sis to a water pipe, radiator, or other ground.

pendent of the other controls on the clock,
