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 pro
-
tection is not maintained. Refer to the Special Precautions
pages in the front of the instruction book for detailed han

dling information.
RF flex coaxial cable requires special consideration. The elec-
trical characteristics of the coax can be affected if it is acci-
dentally twisted or bent. Provide mechanical support to
prevent any weight or strain to the coax and connector
when connecting or disconnecting equipment. Loosen the
connectors at both ends of a coax section if one end must be
moved even slightly. SMA connectors should be secured fin
-
gertight, and then gently tightened using a torque wrench
with a 5/16 in. head set for 7 to 9 inch-pounds. The connec
-
tors should not be left fingertight.
