Shielding effectiveness
Results shown are typical for a standard Grayhill
Series 84S Keyboard. A conductive gasket will
generally increase the shielding, depending on
the size and shape of the gasket and its material.

the frequency source that was radiated from the
transmitting antenna to the enclosed receiving
antenna. The spacing between antennas was
maintained constant throughout the frequency
range. The effectiveness rating is determined
by establishing a reference reading without
obstruction between the two antennas and
determining the difference between that reading
and the test setup reading.

Grayhill maintains a legend library which contains
the most often requested special legends and
many unusual ones. If the legend is in the library,
the cost to utilize this legend in your keypad
configuration is minimal. If the legend is not
available, Grayhill can list the charges required
to add your legend to the library. In this manner,
new legends are added on a periodic basis.
Custom legends to fit your unique requirements
may not be as expensive as you think, contact
Grayhill.
