INSTALLATION INSTRUCTIONS
Aerial
To enable you to get the full p erfo rmance your set was designed to give, Philco
engineers have perfected a sci ent ifi ca ll y design ed aerial known as the Phi leo All- Wave
Aer ial. This ae rial is built for high est response to the popul ar s hort- wave frequencies
as well as th e sta nd ard br oa dca st frequencies.
In addition, yo ur rec eiver ha s bu ilt into it an "a u tom atic aerial sele cto r" (c on -
trolled
by the wave band sel ector) which keeps the aerial a nd set always synchronized
for ma x imum reception, wheth er you are listening to s tandard br oa d casts or sho rt-
wave s tation s.
A fea tu re of the Phileo All- Wave Ae rial is that it qr eatly re duces noise caused by
electrical appliances and equipment in th e vici nit y. Thi s noise-reduction is effective
both on sta nd a rd and s hort- wave freq uencies.
The te rm inals on the panel at re ar of set chassis marked " RED" and "BLA CK"
are for connection to the Phi leo All- Wave Aerial.
Speci
fy a Philco All-Wave Aerial.
(Fo r convenience in c ase an old-style or dinary single-w ir e ae rial is to be used
tempo
rarily , s tandard aerial and ground termin als are pr ov ided on the rece iv er cha ssis.)

Before Operating
Locate the radio at a suitable place in the room , w ith due con sideration to co n-
venience of o peration , appearance, tone, and handy connection to the aeria l t ermi nals
and an electric supply outlet. For b est tone, th e set sho uld be a sho rt di st ance
from the wall.

the knobs
(furni shed in the envelope with th es e ins truction s) on th e co ntro l s hafts.
Note that the "Stati on Sel ec tor" and "Slow-speed Tuning" knobs (see c ut) are different
from the o ther s. The fo rmer goes on the thick (rear) po rtion of the tuning shaft
and the latter on th e thin porti on. Push knobs (except the Slow-speed Tuning Knob)
on to within about ilr inch of the face of the panel.
Insert the electric plug into the nearest electric supply outlet. Be sure the c ur r ent is
of the co rr ect vo lta ge and fr e qu en cy (cy cles), as called for on the namep l ate on chassis.

Th e figures on the stan d ard broadca st scal e, by adding a zero, are "kilo cycles" (K C)
as given in most station lists. For examp le : WJZ (760 KC) com es in at 76; WCA U

Recognizing Foreign Stations
Many foreign stations si gn off or announce in th e ir owB la nguag e and afterward s
in
English, for th e benefit of American and English listeners. In cases where you do
not hear them si gn off, you ma y be able to tell by their f requency (megacycle number
on dial) , th e l anguage used, or type of pro gram, just wha t shor t-wave stat i on you
have tuned in. You will find that once yo u have heard a s tation a few times , you will

ead ily recognize it when you tune it in. A little practice wi ll make yo u proficient in
