MONITOR
In
Figure
6,
the Electronic Keyer
is
showncon-
nected as a monitor. The Volume control should
be
adjusted for the desired output from the
earphones.
BATTERY OPERATION
The Electronic Keyer may be powered with a
45
volt battery having a 22-1/2 volt tap or two
22-1/2 volt batteries connected as shown in
Figure
7.
The slide switch will not turn the bat-
teries off, therefore, an external switch must
be
provided.
If
a switch
is
not used, the batteries
should be disconnected when the Electronic Keyer
is
not in use. The 120 V
AC
line cord should not
be connected to a wall outlet when batteries
are connected to the Electronic Keyer.
