Now locate the connection block with five leads extending from its back at
the side of the cabinet. One of these leads has a green braid with a yellow tracer
and is equipped with a metal tag marked "-A" "+C" and also has a terminal near
its middle, while the other end is attached at the upper left edge of the battery
compartment. Connect this terminal to the negative (edge) terminal of the
top "A" cell and screw the knurled nut down as tightly as possible. One of the
other leads has a yellow braid with red tracer and two terminals, one near the
middle and the other at the end, and is equipped with a metal tag marked
"+A", "-B" "Ground". Connect the terminal near the middle of the lead to
the positive (center) terminal of the bottom dry cell of the "A" battery.
Use "Ground" connection only when an aerial is employed.
Connections from the terminal block to the catacomb are made through a 5
conductor cable connected to the "plug" section of the connection block. The two
sections of the connection block are fitted together when the set is shipped.
If they have come apart or have been separated to facilitate installation of
batteries, put them together again. The pin arrangement is such that the two
sections will fit together in but one way.
After the three cells of the "A" battery have been connected remove
the packing block by pressing down on catacomb (using a screw driver as a
lever) and pulling the block forward and out through the tube opening.
Turn the "Battery" setting knob to the left until the pointer rests on "Off". Then
unpack the six Radiotrons Model UV-l99 which will he found in the battery
compartment of the portable unit. Before placing the Radiotrons in the
sockets, make sure that the bayonet pin at the side of the Radiotron base is in
line with the slot of the socket, then push the Radiotron down in the socket and
turn it slightly to the right where it will remain in a' fixed or locked position.
Turn the "Battery" control knob to "2" and see that the filaments of all the
Radiotrons glow.
Turn the "Volume" control knob all the way to the right to determine if the
third Radiotron from the left glows at normal brilliancy. After determining that
all the Radiotrons are glowing properly, turn the "Battery" control knob back to
"Off", remove the Radiotrons from their sockets and proceed with the installation
of the "B" and "C" batteries.
Remove the "B" battery units from their cartons and place them in the right
half of the battery compartment. They are to be stood on end in two rows with the
tops facing outward as shown in Figure
5
and must he placed exactly as shown.
