Powering Up Instructions
The -5 volts must be applied to the
receiver module before applying
the +5 volts. Likewise when
shutting down the receiver
Mounting Instructions
Case must be mounted firmly,
with screws, to an adequate
metallic structure that has suffi-
cient thermal properties to
turnedoff.The+8.5 voltscanbe
turned on in any sequence. Failure
to follow this procedure could
cause permanent damage to the
module.
