(right for right-hand operation) should re
-
sult in dots being heard from the speaker,
and moving the key to the dash position
(left for right-hand operation) should pro-

DOT-SPACE RATIO ADJVSTMENT
The following adjustment will make the dot-space
ratio equal.
The SPEED and screwdriver adjust controls
are clutch type and will track together to main-
tain the proper dot-space ratio at all settings
of the SPEED control.
If
a
VTVM
is
available, an accurate check of
the dot-space ratio can be made in the follow-
ing manner.
(
)
Set the SPEED control to the
9
o'clock
position.
(
)
Set the slide switch to the OPR position.
(
)
Turn the VOLUME control to the desired
listening level.

Connect the DC test leads of the
VTVM
between the
GND
and
KEYED
LINE screws
of the 8-screw terminal board. Set the
VTVM
to
the
+15
V
DC range.
A
meter reading
of
approximately 3 volts should be obtained,
with the key lever in the center (neutral)
position.
(
)
Wold the key in the dot position. The meter
reading should be
50%
of the preflous read-
ing.
If
not, hold the SPEED control and ad-
just the screwdriver adjust control for the
proper meter reading. Place some object
against the key lever to keep it to the right
(dot position) while making this adjustment.
