Important Safety Information: Intrinsically Safe Radios

FMRC Approved Equipment

Anyone intending to use a radio in a location where hazardous concentrations of flammable material exist (hazardous atmo-
sphere) is advised to become familiar with the subject of intrinsic safety and with the National Electric Code NFPA 70 (National
Fire Protection Association) Article 500 (hazardous [classified] locations).
An Approval Guide, issued by Factory Mutual Research Corporation (FMRC), lists manufacturers and the products approved
by FMRC for use in such locations. FMRC has also issued a voluntary approval standard for repair service ("Class Number
3605").
FMRC Approval labels are attached to the radio to identify the unit as being FM Approved for specified hazardous atmospheres.
This label specifies the hazardous Class/Division/Group along with the part number of the battery that must be used. Their Ap-
proval mark is shown below.
Radios must ship from the Motorola manufacturing facility with the hazardous atmosphere capability and FM Approval label-
ing. Radios will not be "upgraded" to this capability and labeled in the field.
