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

become familiar with the subject of intrinsic safety and with Sec-

tion 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 per-

formed only by qualiﬁed personnel who adhere to the following

Factory Mutual Research Corporation (FMRC) required warning:

WARNING

Certain MTX•LS radios and batteries have been declared intrinsi-

cally safe by FMRC of Norwood, Massachusetts, for use in hazard-

ous atmospheres. FM Approved radios are identiﬁed by attached

certiﬁcation labels and by matching green dots found on the bot-

tom 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 MTX•LS radio has

been thoroughly tested by Factory Mutual Research Corporation

and carries its certiﬁcation for operation in the hazardous atmo-

spheres 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. MTX•LS 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 ap-

provals, are listed in the yearly approval guide published by Facto-

ry Mutual Research Corporation. This guide can be ordered from

the following address:
