Type I Simulator Card: Remove the Type I
Simulator Card from mainframe position 2.
In addition to the identification label, this
card can be identified by the empty parts
locations on the circuit board. You will
observe a section in the middle of the board
where parts have not been inserted. There
are no switches to be set, or initial adjust-
ments to be made on the Type I Simulator
Card. Confirm that single turn trim potenti-
ometer R43 is set to the 50% rotation point,
i.e., halfway between fully clockwise and
fully counterclockwise. R43 is small and
basically round, and is located near the
front edge of the card. This pot was preset
at the factory but a visual check is a good
idea. DO NOT TOUCH ANY OTHER PO-
TENTIOMETER ON THIS CARD OR FAC-
TORY CALIBRATION MAY BE REQUIRED.
This card is now installed in mainframe card
position 2.
Polarity Correction Card: Remove the Polar-
ity Correction Card from mainframe position
3. One switch must be set on the Polarity
Correction Card. This switch determines the
type of remote control signal that is going to
be used for the Remote Polarity Correction
Function Disable command. In the CONT
position a continuous signal will be applied.
In the PULSE position a momentary signal
will be applied. If you are not going to be
connecting a remote control signal the
switch should be in the CONT position. This
card is now installed in card position 3.
Type II Simulator Card: Remove the Type II
Simulator Card from mainframe position 4.
In addition to the identification label, this
card can be identified by the fact that,
unlike the Type I card, most of the compo-
nents in the Type II printed circuit board
have been inserted. There are no switches
to be set, or initial adjustments to be made
on the Type II Simulator Card. Confirm that
single turn trim potentiometer R43 is set to
the 50% rotation point, i.e., halfway between
fully clockwise and fully counterclockwise.
This pot is in the same location, and is
labeled R43 on both the Type I and Type II
cards. This pot was preset at the factory
and should only require a visual confirma-
tion of the correct setting. This card is now
installed in card position 4.
Crossfade Card: Remove the Crossfade
Card from mainframe card position 5. One
switch, INPUT, must be set on the Cross-
fade Card. This switch selects which audio
signal is connected to the card from the
ribbon cable bus. If, as is usual, the Polarity
Correction Card is installed, set the switch
to the B position. If, for reasons such as
repair, etc., the Polarity Correction Card is
not installed, set the switch to the A posi-
tion. If a Tone Detection Card is present in
your system the INPUT switch is set to the
C position. This card is installed in card
position 5.
Recognition Card: Remove the Recognition
Card from mainframe card position 6. There
are two switches that must be set on the
Recognition Card. The INPUT switch se-
lects which audio signal is connected to the
card from the ribbon cable bus. If, as is
usual, the Polarity Correction Card is in-
stalled, set the switch to the B position. If,
for reasons such as repair, etc., the Polarity
Correction Card is not installed, set the
switch to the A position. If a Tone Detection
Card is present in your system the INPUT
switch is set to the C position. The other
switch is a four position DIP type. This
switch decides which recognition modes
will be active. One, two, or all three modes
