Safety Standards (cont.)

Anyone intending to use a radio in a hazardous area is advised to become

familiar with the subject of intrinsic safety and with Section 70 of the National Fire

Code, which is commonly referred to as Article 500 of the National Electric Code.

Use of anything but factory supplied components may affect the approval and

safety of the radio. Likewise, it is advised that servicing should be performed only

by qualified personnel who adhere to the following Factory Mutual Research

Corporation (FMRC) required warning:

Modification of FMRC-Approved intrinsically safe radios will

negate Factory Mutual Research Corporation Approval.

Certain JT 1000 radios and batteries have been declared intrinsically safe by

FMRC of Norwood, Massachusetts, for use in hazardous atmospheres. FM

Approved radios are identified by attached certification labels and by matching

green dots found on the bottom of radios and batteries. The intrinsically safe

rating by Factory Mutual Research Corporation states that electrical equipment is

incapable of releasing sufficient electrical or thermal energy, under normal or

abnormal operating conditions, to cause ignition of a specific hazardous

atmosphere. This means the JT 1000 radio has been thoroughly tested by

Factory Mutual Research Corporation and carries its certification for operation in

the hazardous atmospheres designated on the radio label. Radios must ship

from the Motorola factory with the hazardous atmosphere capability and

cannot be modified in the field. Failure to use the radio with the approved battery

will negate the approval. JT 1000 radios that are approved by Factory Mutual

Research Corporation can be used in those applications requiring reliable two way

hand-held radios in the listed specific hazardous atmospheres. Motorola approved

equipment and accessories, along with competitive equipment approvals, are listed

in the yearly approval guide published by Factory Mutual Research Corporation. This

guide can be ordered from the following address:
