Special Conditions for Safe Use (X):
1. The surface resistivity of the antenna is greater than 1 GΩ. To avoid
electrostatic charge build-up, it must not be rubbed or cleaned with
solvents or dry cloth.
2. The Model 701PBKKF Power Module, MHM-89004 Blue Power
Module, or Intelligent Power Module 71008 may be replaced in a
hazardous area. The Power Modules have a surface resistivity greater
than 1 GΩ and must be properly installed in the wireless device
enclosure. Care must be taken during transportation to and from the
point of installation to prevent electrostatic charge build-up.
3. The Rosemount 702 enclosure may be made of aluminum alloy and
given a protective polyurethane paint finish; however, care should be
taken to protect it from impact or abrasion if located in a Zone 0
area.
