OPERATING INSTRUCTIONS
TO OPEN BACK COVER.
With the
fingers,
grasp back
cover
at top and
pull
open.
When closing the cover, be
careful not to pinch the power line cord or other leads be¬
tween the cover and the cabinet.
HOUSE
CURRENT
OPERATION.
The
power
cord is lo¬
cated inside the cabinet and can be reached by opening the
back cover.
Pass the cord through the slot on the side of
the
receiver
before
closing the
cover.
Cover
must be
closed or receiver
will not operate.
(A safety interlock
switch turns the
current off whenever the back cover is
opened.)
Plug the cord into any 117 volt AC or DC power
outlet.
Reverse the plug in the outlet if the receiver does
not operate from DC power.
When operating from AC, re-
ceptionmay sometimes be improved by reversing the power
plug in the outlet.
It is not necessary that batteries be in¬
stalled if the receiver is to be operated only from house
power lines.
BATTERY OPERATION.
Open the back cover and install
the batteries by following the instructions on the label lo¬
cated inside the cover, or refer to Figure 4. Plug the power
line cord into the receptacle on the chassis, or the receiver
will not operate from batteries.-
If the radio is to be op¬
erated for a long period of time from house power lines, or
is to be placed in storage, remove the batteries anc keep
them in a cool place.
IMPORTANT:
Never
leave
low or
run-down batteries in the receiver, as they will swell or
leak and damage the set.
ANTENNA.
A Ferrite Magnetic Iron Core Antenna is built
into this receiver. Because of the slightly directional char¬
acteristics
of the
built-in antenna, reception from some
stations may be improved by rotating the receiver.
In ex¬
tremely noisy locations, rotate the set until minimum noise
and maximum signal pick-up are obtained.
BATTERY REPLACEMENT. Replace the battery pack when
low volume or fuzzy tone is noticed.
Complete battery re¬
placement instructions will be found inside the back cover,
or refer to Figure 4.
Normally, the 67-1/2 volt "B" bat¬
tery will
last
for
3 or
4
changes
of the "A" batteries.
NOTE:
The condition of the batteries will not affect opera¬
tion of the receiver from the house power lines.
