Aerials
The receiver has two built-in aerials; a lerrite aerial which operates on LW
and MW; and a telescoping whip that operates on SW2 and SW l. These
two aerials
are the regular aerialsof the receiver; they are designed to provide
a very high order oI sensitivity on all wave bands. Where reception is
desired under poor conditions, such as in a closed motor-car or in a Ïerro-
concrete building, best results
will be obtained if an external aerialisconnected
to the receiver's aerial jack. If reception is poor indoors and no outdoor aerial
is available, an improvement will be obtained by placing the receiver near a
window.
The ferrite aerialis mounted longitudinally in the receiver, and asit possesses
a certain amount of directivity the receiver should be rotated slowly back and
forth until best reception is obtained. Likewise, an undesired station can be
suppressed by similarly rotating the receiver for minimum signal from the sta-
tion in question. This may possibly reduce the signal from the desired station
as well, but since the angle over which the desired station is strong is much
wider than that in which the undesired station is suppressed,considerable irn-
provement is possible with the procedure described.
The telescoping whip (SW 2 and SW 1)has no directivity. It should be pulled
out to its full length so that maximum sensitivity will be obtained.
Taking Bearings
The directional properties of the receiver when the built-in aerial is used can
be utilized for taking bearings.The procedure is as follows: Tune in a station
whose location you know, for instance one of the marine radio beacons ope-
rating between 300 and 320 Kc/s in the Long Wave band, and then rotate
2
I

the receiver îor minimum signal. As mentioned above, this direction is very
well-defined, and the station will therefore be found on a straight line length-
wise through the receiver. Next, the direction of the line through the station
is drawn on a map that is oriented with respect to the four points of the com-
pass,and a second bearing is taken on another station. This bearing, too, is
drawn on the map, and the location of the receiver is now found asthe point
where the two linesinterse
ct.
A check may be obtained by taking a third bearing.
Batterl
Six size C flashlight cells comprise the 9 volt battery. The servicelife of a set
of dry cells is between 150 and 200 hours, depending on the type used and
the volume level at which the receiver is operated.The current consumption is
increasedasthe volume control is advanced.
When the set does not operate, or distortion becomes apparent, the dry cells
should be replaced. You can do this yourself, or ask your dealer to do so.
Loosen, by rneansof a coin, the screw which holds
the battery compartment cover on the underside oI
the receiver. Remove the cover and insertthe cells
as shown in the illustration and as outlined by
marks on the underside of the cover.

Dry cells are not installed in your set when shipped from the factory. Your
dealer will be glad to install a fresh set at the time of purchase. It is advisable
that the metal-clad "leakproof" type be used to insure against damage to the
battery compartment. It is unwise to leave the radio with spent dry cells in it,
and if the radio is not to be usedfor several
months, thecellsshould be removed.
All six cellsshould be rcplaced at the sametime.
Preserve battery life by making sure the receiver is suitched o;f when not in
use.Tuning the volume down does not turn the set off.
External Speahn
Your receiver has provision Ior connecting an external speaker so that you
will be able to enjoy even finer performance than is possible with the space
limitation of a transistor
portable. Connecting another speakerwill automatically
switch off the built-in speaker.Standard miniature phone plugs for this connec-
tion may be obtained from your dealer.
