Operational Cautions
Intrinsically Safe Radio Information
The Intrinsically safe approval unit refers to a product that has been approved as intrinsically safe by
an approval agency (for example FM Approvals, CSA, UL, or Cenelec) and certifies that a particular
product meets the Agency's applicable intrinsic safety standards for specific types of hazardous
classified locations. A portable radio that has been approved for intrinsic safety will have Approval
label attached to the radio to identify the unit as being 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. The intrinsically safe approval label will be located on the portable
radio unit.
Operational Cautions for Intrinsic Safe Equipment
Warnings for Radios Approved as Intrinsically Safe
Radios must ship from the Motorola manufacturing facility with the hazardous atmosphere capability
and the intrinsic safety approval labelling (FM, UL, CSA, CENELEC). Radios will not be upgraded to
this capability and labeled once they have been shipped to the field.
Antennas
Do not use any portable radio that has a damaged antenna. If a damaged antenna comes into contact
with your skin, a minor burn can result.
Batteries
All batteries can cause property damage and/or bodily injury, such as burns, if a conductive material
such as jewelry, keys, or beaded chains touches exposed terminals. The conductive material may
complete an electrical circuit (short circuit) and become quite hot. Exercise care in handling any
charged battery, particularly when placing it inside a pocket, purse, or other container with metal
objects.
• Do not operate radio communications equipment in a hazardous atmosphere unless it is a type
especially qualified (for example, FM, UL, CSA, or CENELEC approved). An explosion or fire may
result.
• Do not operate a radio unit that has been approved as intrinsically safe product in a hazardous
atmosphere if it has been physically damaged (for example, cracked housing). An explosion or fire
may result.
• Do not replace or charge batteries in a hazardous atmosphere. Contact sparking may occur while
installing or removing batteries and cause an explosion or fire.
