NIOSH APPROVAL INFORMATION
CAUTIONS AND LIMITATIONS
I - Contains electrical parts which have not been evaluat-
ed as an ignition source in flammable or explosive
atmospheres by MSHA/NIOSH.
N - Never substitute, modify, add, or omit parts. Use only
exact replacement parts in the configuration as specified by the manufacturer.
S - Special or critical User’s Instructions and/or specific
use limitations apply. Refer to User’s Instructions
before donning.
SPECIAL OR CRITICAL USER’S INSTRUCTIONS
1. Do not alter this unit. You will void the intrinsic-safety
rating, and may affect the intrinsic-safety of the
device.
2. Evaluate this unit, and any radio transceiver with
which it may be used, before entering a hazardous
atmosphere. Be certain that this unit is not affected
adversely by radio frequency energy.
3. Evaluate this unit, and any radio transceiver with
which it may be used, as a source of radio frequency
interference to other apparatus before entering a hazardous atmosphere.
4. Misuse or abuse of the ClearCommand
Communications System, or the equipment to which it
is attached, or using this equipment in a manner or
situation not intended by the manufacturers, may
result in damage to the ClearCommand, or equipment
connected to the ClearCommand Communications
System, or may result in personal injury or death to
the user or persons dependent on the user.
5. Always inspect the ClearCommand Communications
System for damage before use. If damage is found,
tag the cable and immediately remove the device from
service. NEVER USE A DAMAGED OR NON-FUNCTIONAL COMMUNICATION SYSTEM!
DESCRIPTION
The ClearCommand Communications System Amplifier
Radio Interface (RI) Version allows a user to communicate
clearly and easily, both face-to-face and over a hand-held
radio, while wearing an SCBA equipped with an Ultra
Elite Facepiece.

The system consists of three main components that
attach to the user’s radio:
• An internal microphone assembly
• An Amplifier or Amplifier RI hooked to the facepiece
with a mounting bracket. The Amplifier RI (Radio
Interface) includes an ear speaker and a cable to connect to a lapel microphone or Push-To-Talk.
• A Lapel Microphone or optional Basic Push-To-Talk
(PTT) with specific radio interface connection. The
amplifier can be attached or removed from the facepiece in seconds without tools.
Note: To complete the system, the user must select and
purchase the proper Lapel Microphone or Basic Push-ToTalk (PTT) Unit that fits their specific radio. (see Table in
Parts List)
When the Amplifier RI Assembly is connected to the Lapel
Microphone, communication is the same as with the
Basic PTT interface.
The Lapel Microphone Unit can be used without the
Amplifier RI. The Lapel Microphone interface contains a
remote speaker and microphone with a Push-To-Talk
Button. This unit allows remote, shoulder mounted, radio
transmission and reception.
When the Amplifier RI Microphone is connected to the
Basic PTT, the user presses the button to transmit and
incoming radio messages are heard at the Amplifier RI ear
speaker.
The Lapel Microphone is equipped with the following:
• Female connection for the male connector of the helmet microphone assembly.
• Belt clip on the back of the Lapel Microphone for
attaching the Lapel Microphone to the user’s clothing.
(An optional, clothespin type clip assembly is also
available as an accessory)
• Microphone, speaker, and a Push-To-Talk Button.
• The Push-To-Talk Button is protected against inadvertent operation by a guard. The unit is shipped with the
taller guard. When the taller guard is removed, the
Push-To-Talk Button becomes fully exposed and easier to access. The shorter guard is included and available for replacement.
• Cable and radio-specific connector.
• Connection port for an optional remote finger PushTo-Talk Button used when wearing a Level A Suit.

Intrinsically-Safe Rating
The ClearCommand Communications System is certified
ntrinsically-Safe in the United States for use in Class 1,
I
Division 1, Groups A, B, C, D, E, F, and G hazardous locations.
The ClearCommand Communications System is certified
intrinsically-safe in Canada CAN CSA-C22-2-No.157-92.
Failure to follow this warning can result in serious personal injury or death.
Note: The intrinsically-safe level of any system which
uses the ClearCommand Communications System is that
of the lowest intrinsically-safe rating of any single component in the system.
Risk of Explosion - Use only Helmet Communication
Systems with the proper intrinsically safe rating in
hazardous environments. Misuse can result in serious
personal injury or death.

Ensure each component of the intrinsically safe system is
suitable for the Hazardous (Classified) Location prior to
entering.
Substitution of components may eliminate or compromise intrinsic safety.
Ensure the radio used is intrinsically safe before entering a hazardous atmosphere. Failure to following this
warning can result in serious personal injury or death.
The ClearCommand Communications System must be
tested before entering a hazardous atmosphere. If the
ClearCommand Communications System fails to operate as designed, disconnect at the radio and use the
radio independently from the communication system.
