SPECIAL USERS 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 atmos-
phere. 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 interfer-
ence to other apparatus before entering a hazardous
atmosphere.
4. Misuse or abuse of the ClearCommand, or the equip-
ment to which it is attached, or using this equipment
in a manner or situation not intended by the manufac-
turers, may result in damage to the ClearCommand, or
equipment connected to the ClearCommand, or may
result in personal injury or death to the user or per-
sons dependent on the user.
5. Always inspect the communications system for dam-
age before use. If damage is found, tag the cable and
immediately remove the device from service. NEVER
USE A DAMAGED OR NON-FUNCTIONAL COMMU-
NICATIONS SYSTEM!
Note: The ClearCommand Amplifier or Amplifier RI are for
use with an Ultra Elite facepiece. They cannot be used
without the proper installation of the ClearCommand
Bracket and Voicemitter Kit from MSA (P/N 10023055)
DESCRIPTION
The ClearCommand™ Communication System (Amplifier
RI Version) allows a user to communicate clearly and easi-
ly, both face-to-face and over a hand-held radio, while
wearing an SCBA equipped with a Ultra Elite facepiece.
The ClearCommand Voice Amplifier consists of three sep-
arate assemblies: An internal microphone assembly, a
mounting bracket, and either a voice amplifier or a voice
amplifier with radio interface. The voice amplifier RI (radio
interface) includes an earspeaker and cable to connect to
a radio unit. Each amplifier has a Low Battery LED indica-
tor. The amplifier can be attached or removed from the
facepiece in seconds without tools.
The amplifier operates from two standard AAA alkaline
batteries and notifies the user when the batteries need
replaced.
Intrinsically-Safe Rating
The ClearCommand Communication System is certified
Intrinsically-Safe in the United States for use in Class 1,
Division 1, Groups A, B, C, D, E, F, and G hazardous loca-
tions.
The ClearCommand Communication System is certified
intrinsically-safe in Canada CAN CSA-C22-2- No. 157-92
Note: The intrinsically-safe level of any system which
uses the ClearCommand is that of the lowest intrinsically-
safe rating of any single component in the system.
Substitution of components may eliminate or compro-
mise intrinsic safety.

PREPARING FOR USE
PREPARING FOR USE
Assembly of Amplifier or Amplifier RI to Bracket
1. Ensure dust cover is
removed from mount-
ing bracket (two pins)
connector.
2. Attach the amplifier
onto the bracket with
the hook at the front of
the amplifier. Align the
amplifier so two pins of
the connector are cor-
rectly in position, press
the amplifier into place
on the bracket and
tighten thumbscrew on
back side of mounting
bracket.
3. If not using radio, wrap the cable around the lens ring
and connect the cable to the clip on the right side.
Always test the ClearCommand Communication
System for damage and be sure it operates properly
before entering any hazardous atmosphere. Do not
use this device unless it passes all inspection and
operational tests. Failure to follow this precaution can
result in serious personal injury or death.
Amplifier
1. Don the SCBA Ultra Elite facepiece following the
instructions supplied with the SCBA.
2. Turn the Voice Amplifier ON:
a. Depress the on/off button on the Amplifier and then
release it.
b. Look through the facepiece lens. A small, red LED
should be illuminated at the top of the amplifier
housing. If the LED is flashing, the battery is low
and must be replaced before you use the Amplifier.
c. For amplifier full-time use, the on/off button must
be ON. All face-piece audio is reproduced at the
amplifier.
Note: The on/off button remains ON until you press and
release the button. Always be sure to turn the unit OFF
(red LED should not be illuminated) before storing the
facepiece. If left ON, the battery will be depleted.
3. Speak into the facepiece in a normal voice. Your voice
is projected from the amplifier’s speaker.
Amplifier Radio Interface (RI)
Read and follow the Amplifier RI procedure. Be sure to
observe all CAUTIONS, WARNINGS, and NOTES. Before
donning the facepiece, check that the radio interface connec-
tor is attached to your radio before use.
Note: The Radio Interface must be used with the Amplifier
RI On/off button turned ON.
Amplifier Radio Interface (RI) System Operations
1. Don the SCBA Ultra Elite facepiece following the
instructions supplied with the SCBA.
2. Attach the Amplifier RI cable to the radio unit.
3. Adjust the radio volume control for an acceptable
audio level.
4. All received audio will be heard on the earspeaker of
the amplifier RI. Your radio’s internal speaker is dis-
abled in this configuration.
5. You can enable the Voice Amplifier for full-time use by
depressing the amplifier’s on/off button to turn the unit
ON.
a. If the amplifier is on, the red LED should be illumi-
nated at the top of the amplifier housing.
b.All facepiece audio is reproduced in the amplifier’s
speaker.
c. All incoming radio transmissions is received in the
Amplifier RI’s earspeaker.
Using the Radio Without the Amplifier RI
To use the radio independent of the Amplifier RI detach
the radio connector from the radio.
CLEANING AND MAINTENANCE
The ClearCommand should be cleaned and disinfected
after each use. Follow an established cleaning and disin-
fecting program. Failure to follow this procedure can
damage the Clear Command.
Remove the Amplifier from the Apparatus
1. Unscrew the thumbscrew and disconnect the amplifier.
2. Reconnect the dust cover in the (two pins) connector.

PREPARING FOR USE
CLEANING AND DISINFECTING
1. Prepare a cleaning solution by adding Confidence
Plus™ Cleaner (P/N 10009971) to water, following the
instructions on the Confidence Plus™ Cleaner con-
tainer.
Never submerge the ClearCommand Communication
System modules in water or any other liquid.
2. Clean by wiping with a damp sponge or cloth contain-
ing Confidence Plus Cleaner from MSA. Follow the
directions on the Confidence Plus container for mixing
directions and recommended times.
INSPECTION
1. Inspect the ClearCommand modules. Look for cracks
or other signs of damage which could allow contami-
nants to enter the module housings. Check that the
battery compartment is clear of moisture or debris.
2. Reassemble the amplifier module on the Ultra Elite
facepiece.
3. Check out the system functions.
a. Depress the on/off button on the ClearCommand
unit and then release it.
b. Look through the facepiece lens. The red LED
should be illuminated at the top of the amplifier unit.
c. Scrape your fingernail lightly across the voicemitter
microphone grille of the voicemitter microphone
assembly.
d. You should hear this sound reproduced in the
amplifier speaker.
e. Depress and release the on/off button again to turn
the unit OFF. The LED on the amplifier unit should
be OFF.
STORAGE
To store the ClearCommand components, be sure that
unit is in the OFF (red LED is not illuminated) position. For
prolonged storage, remove the batteries to prevent bat-
tery corrosion. Store the units in a cool, dry place.
Installing the Batteries
Use only Duracell NEDA 24A or Eveready NEDA 24AC
AAA alkaline batteries. Use of other batteries will void
the intrinsic safety approval.
1. Loosen the thumbscrew to open battery door.
2. Insert two AAA batteries according to the battery ori-
entation noted inside the compartment.
3. Close the battery door and tighten the thumbscrew.
Battery Disposal
In continuous service, battery life is approximately 14 to
16 hours. Battery life will vary depending on user condi-
tions. The battery is not rechargeable. Do not dispose of
the battery in fire. It may explode! Failure to follow this
precaution can result in serious personal injury or death.
