MODULE REPLACEMENT

5.8
Modules screwed to heat sink must be screwed securely before
power is turned on.
Units with the electrostatic-sensitive (ESS) symbol contain ESS
devices. Store these units in an antistatic container when not in use,
and anyone handling a unit should observe antistatic precautions.
Damage to the unit may result if antistatic protection is not main-
tained. Refer to the Special Precautions pages in the front of the
instruction book for detailed handling information.
RF flex coaxial cable requires special consideration. The electrical
characteristics of the coax can be affected if it is accidentally twisted
or bent. Provide mechanical support to prevent any weight or strain
to the coax and connector when connecting or disconnecting equip-
ment. Loosen the connectors at both ends of a coax section if one
end must be moved even slightly. SMA connectors should be secured
fingertight, and then gently tightened using a torque wrench with a
5/16 in. head set for 7 to 9 inch-pounds. The connectors should not
be left fingertight.
XMTR Crystals should never be shipped as replacements without
being soldered and tuned up in an oscillator assembly board at the
factory.
