that all crevices are dry and clean. The surface should be rubbed until the finish

HOME BATTERY BOX
The Home Battery Box for use with the Radiola 26 has two distinct and
separate functions. It is designed primarily as a means of holding in a neat and
attractive manner a set of larger batteries which will give long and economical
service. It is also equipped with a tuning circuit for use with an antenna.
To install the batteries in the Home Battery Box it is necessary to remove
the top which is held in place by six screws located near the ends and
sides. When these screws have been taken out, the top can be removed.
Three compartments will be found in the Home Battery Box. The center
compartment is reserved for the "Antenna Tuner" and nothing should be
placed in it. The compartment at the left should be used for the "A" and "C"
batteries while the compartment at the right is to be used for the "B" batteries.
The batteries are to be located as in Figs. 6 and 7. The six dry
cells forming the "A" battery are to be connected in two parallel groups of three
cells each in series. The exact method of making connections may be best
understood by reference to the diagram Fig. 10. Connections between cells are
to be made by the short jumpers furnished with the Home Battery Box. Find
the lead with yellow braid and red tracer having a metal tag marked "+A", "—
B", "Ground", and connect its terminals to the two free positive (center)
terminals of the dry cells. Next find the lead having the green braid with
yellow tracer and having a metal tag marked "—A", "+C", and connect its
two end terminals to the free negative (edge) terminals of the dry cells. The
third terminal on this same lead is to be connected to the positive terminal of
the "C" battery. Complete the "C" battery connection by finding the lead with a
black braid and green tracer having a metal tag marked "—C", and connecting
its terminal to the negative terminal of the "C" battery.
The "B" battery for use in the Home Battery Box may consist of
either four blocks of 22 ½-volt "B" battery (large size) or it may consist of two
blocks of 45-volt "B" battery (large size.) In case 22 ½-volt blocks are
used, they should be connected in series, i. e., the positive binding post on No.
1 should be connected to the negative of No. 2, etc. In case two 45-volt
blocks are employed, the positive binding post or terminal of No. 1 is con-
