before onning.
SPECIAL OR CRITICAL USER’S INSTRUCTIONS
1. Do not alter this unit. You will voi the intrinsic-safety
rating, an may affect the intrinsic-safety of the
evice.
2. Evaluate this unit, an any ra io transceiver with
which it may be use , before entering a hazar ous
atmosphere. Be certain that this unit is not affecte
a versely by ra io frequency energy.
3. Evaluate this unit, an any ra io transceiver with
which it may be use , as a source of ra io frequency
interference to other apparatus before entering a haz-
ar ous atmosphere.
4. Misuse or abuse of the ClearComman
Communications System, or the equipment to which it
is attache , or using this equipment in a manner or
situation not inten e by the manufacturers, may
result in amage to the ClearComman , or equipment
connecte to the ClearComman Communications
System, or may result in personal injury or eath to

TIONAL COMMUNICATION SYSTEM!
DESCRIPTION
The ClearComman Communications System Amplifier
Ra io Interface (RI) Version allows a user to communicate
clearly an easily, both face-to-face an over a han -hel
ra io, while wearing an SCBA equippe with an Ultra
Elite Facepiece.
The system consists of three main components that
attach to the user’s ra io:
• An internal microphone assembly
• An Amplifier or Amplifier RI hooke to the facepiece
with a mounting bracket. The Amplifier RI (Ra io
Interface) inclu es an ear speaker an a cable to con-
nect to a lapel microphone or Push-To-Talk.
• A Lapel Microphone or optional Basic Push-To-Talk
(PTT) with specific ra io interface connection. The
amplifier can be attache or remove from the face-
piece in secon s without tools.
Note: To complete the system, the user must select an
purchase the proper Lapel Microphone or Basic Push-To-
Talk (PTT) Unit that fits their specific ra io. (see Table in
Parts List)
When the Amplifier RI Assembly is connecte to the Lapel
Microphone, communication is the same as with the
Basic PTT interface.
The Lapel Microphone Unit can be use without the
Amplifier RI. The Lapel Microphone interface contains a
remote speaker an microphone with a Push-To-Talk
Button. This unit allows remote, shoul er mounte , ra io
transmission an reception.
When the Amplifier RI Microphone is connecte to the
Basic PTT, the user presses the button to transmit an
incoming ra io messages are hear at the Amplifier RI ear
speaker.
The Lapel Microphone is equippe with the following:
• Female connection for the male connector of the hel-
met 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, an a Push-To-Talk Button.
• The Push-To-Talk Button is protecte against ina ver-
tent operation by a guar . The unit is shippe with the
taller guar . When the taller guar is remove , the
Push-To-Talk Button becomes fully expose an easi-
er to access. The shorter guar is inclu e an avail-
able for replacement.
• Cable an ra io-specific connector.
• Connection port for an optional remote finger Push-
To-Talk Button use when wearing a Level A Suit.

INTRODUCTION
The amplifier operates from two stan ar AAA alkaline
batteries an notifies the user when the batteries nee
replace . Each Amplifier an Amplifier RI has a low bat-
tery LED in icator.
Intrinsically-Safe Rating
The ClearComman Communications System is certifie
Intrinsically-Safe in the Unite States for use in Class 1,
Division 1, Groups A, B, C, D, E, F, an G hazar ous loca-
tions.
The ClearComman Communications System is certifie
intrinsically-safe in Cana a CAN CSA-C22-2-No.157-92.
Failure to follow this warning can result in serious person-
al injury or eath.
Note: The intrinsically-safe level of any system which
uses the ClearComman Communications System is that
of the lowest intrinsically-safe rating of any single compo-
nent 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 Hazar ous (Classifie ) Location prior to
entering.
Substitution of components may eliminate or compro-
mise intrinsic safety.
Ensure the radio used is intrinsically safe before enter-
ing 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 oper-
ate as designed, disconnect at the radio and use the
radio independently from the communication system.

Note: If the Lapel Microphone or the Basic PTT requires a
two-pin connector, the wrong Lapel Microphone or Basic
PTT is being use .
Evaluate this unit and any radio transceiver with which
it may be used. Be certain the unit is not affected
adversely by radio frequency energy.
Evaluate this unit and any radio transceiver with which
it may be used as a source of radio interference to
other apparatus before entering a hazardous atmos-
phere.
The lapel microphone and Push-To-talk have a cable
supplied by the radio manufacturer that may or may
not be chemical and flame resistant. The Push-To-
Talk, lapel microphone, cable, and radio must be pro-
tected from flame, chemicals, and CBRN agents.
Using the Radio Without the Amplifier RI
1. To use the ra io in epen ent of the Amplifier RI,
etach the ra io connector from the ra io accor ing
to the ra io manufacturer’s proce ures.
Should any component of the system fail, the user
must disconnect the Lapel Microphone Cable from the
radio and then hold the radio to the facepiece
voicemitter for the stand-alone operations of the
radio.
CLEANING AND MAINTENANCE
The ClearComman Communications System shoul be
cleane an isinfecte after each use. Follow an estab-
lishe cleaning an isinfecting program. Failure to follow
this proce ure can amage the ClearComman
Communications System.
Remove the Amplifier from the Apparatus
1. Unscrew the thumbscrew an isconnect the amplifier.
2. Close the ust cover on the (two pin) connector.
Cleaning and Disinfecting
2. Prepare a cleaning solution by a ing Confi ence
Plus®Cleaning Solution (P/N 10009971) to water, fol-
lowing the instructions on the Confi ence Plus con-
tainer.
Although the system is water resistant, never sub-
merge the ClearCommand Communications System
modules in water or any other liquid.
