personal computer graphics program and
laser printed onto 3M CG3300 (or equiva-
lent) transparency film. The desired button
labels can be cut out with a pair of scissors
or an X-ACTO® knife following the printed
guide lines that indicate the required size.
The clear lens on top of each button cap
can be removed with a fingernail or small
screwdriver. Be certain not to scratch the
button cap or lens if a screwdriver or other
small tool is used. The clear label should
then be set in place. To complete the task
snap the lens back into the top of the but-
ton caps using finger-pressure only. No
tool is required to replace them.
If you need to make your own button labels
the process is quite simple. Use a personal
computer to create the desired text. The
finished label size should be 0.625-inches
(15.8 mm) square. The completed artwork
can then be printed on transparency film
sheets using a laser or inkjet printer. These
sheets are available from most office
supply sources. A pair of scissors or an
X-ACTO knife will complete the task.
Configuration
For the Model 240 to support the needs
of specific applications a number of operat-
ing parameters may be configured. These
include microphone preamplifier gain,
program audio routing, headphone source
selection, and various operating modes.
Three 8-position and one 12-position DIP-
switch assemblies are used to establish
the desired configuration. These switch
assemblies are referred to as SW1 through
SW4, with individual switches designated
as SW1-1, SW1-2, etc. The switch assem-
blies are accessed through openings in
the bottom of the Model 240’s enclosure.
The enclosure does not have to be disas-
sembled to access the switches.
To prevent unauthorized personnel from
changing the configuration settings, a se-
curity plate is attached to the bottom of the
Model 240’s enclosure. For convenience,
text and graphics on the security plate
provide a summary of the configurable
parameters and related information. Refer
to Appendix A at the end of this guide for
a representative view. The security plate
is held in place by means of four rubber
bumpers (“feet”) that have built-in screws.
Using your fingers, remove the four bum-
pers so that the plate can be removed.
Refer to Figure 4 for a detailed view of the
configuration switch assemblies.
