Powering Up Instructions
The -5 volts must be applied to the
transmitter module before
applying the +5 volts. Likewise
when shutting down the transmit-
ter module the +5␣ volts must be
removed before the -5 volts is
turned off. The +10␣ volts can be
turned on in any sequence. Failure
to follow this procedure could
cause permanent damage to the
module.
Mounting Instructions
Case must be mounted firmly,
with screws, to an adequate
metallic structure that has suffi-
cient thermal properties to
maintain the module case at a
temperature not to exceed 70°C.
