snapped back into the top of the button
housing using finger-pressure only. No
tool is required to replace the button cap.
If you need to make your own 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 readily available from most
office supply stores. A pair of scissors or
an X-ACTO® knife will complete the task.
Configuration
For the Model 210 to support the needs
of specific applications a number of op-
erating parameters must be configured.
These include microphone preamplifier
gain, phantom power on/off, headphone
source selection, headphone stereo/
mono mode, and operating modes. Three
8-position DIP-type switch assemblies are
used to establish the desired configura-
tion. These switch assemblies are referred
to as SW1, SW2, and SW3, with individual
switches designated as SW1-1, SW1-2,
etc. The switch assemblies are accessed
through openings in the bottom of the
Model 210’s enclosure. The enclosure
does not have to be disassembled to gain
access to the switches.
To prevent unauthorized personnel from
changing the configuration settings, a
security plate is attached to the bottom
of the Model 210’s enclosure. For conve-
nience, attached to the security plate is
a configuration settings label. It provides
a summary of the configurable parameters
and related information. Refer to Ap-
pendix A for a representative view of the
label. 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 bumpers so that the plate
can be removed. Refer to Figure 3 for a
detailed view of the configuration switch
assemblies.

Microphone Preamplifier Gain
and Phantom Power
Five switches are used to set the gain of
the microphone preamplifier. One switch
is used to select the on/off status of the
phantom power supply.
