PREPARING FOR USE
a. With the radio off, connect the Lapel Microphone or
Basic PTT to the radio with the cable located at the
bottom of the unit. Then, turn the radio ON.
Note:
There are various types of radio cable connectors.
Ensure that the radio cable connector is for the radio
model being used. Also be sure the connector is attached
securely using the attachment method incorporated in the
connector.
b. Depress the tab on the belt clip to open the clip.
The belt clip can rotate to conveniently position the
unit.
c. Attach the belt clip in a convenient location that will
make it easy to connect the Amplifier RI Cable.
Note:
An optional, clothespin style clip assembly is avail-
able as an optional spare part to attach Lapel Microphone
or Basic PTT to clothing (See Replacement Parts).
4. Adjust the radio volume control to an acceptable
audio level.
5. All received audio will be heard on the earspeaker of
the Voice Amplifier RI. The radio’s internal speaker is
disabled in this configuration.
6. The Voice Amplifier can be enabled for full-time use by
depressing the amplifier’s on/off button to 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
Voice Amplifier RI’s earspeaker.
Note:
If the Lapel Microphone or the Basic PTT requires a
two-pin connector, the wrong Lapel Microphone or Basic
PTT is being used.
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 radio independent of the Amplifier RI,
detach the radio connector from the radio according
to the radio manufacturer’s procedures.
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 ClearCommand Communications System should be
cleaned and disinfected after each use. Follow an estab-
lished cleaning and disinfecting program. Failure to follow
this procedure can damage the ClearCommand
Communications System.
Remove the Amplifier from the Apparatus
1. Unscrew the thumbscrew and disconnect the amplifier.
2. Close the dust cover on the (two pin) connector.
Cleaning and Disinfecting
2. Prepare a cleaning solution by adding Confidence
Plus
®
Cleaning Solution (P/N 10009971) to water, fol-
lowing the instructions on the Confidence Plus con-
tainer.
Although the system is water resistant, never sub-
merge the ClearCommand Communications System
modules in water or any other liquid.
3. Clean by wiping with a damp sponge or cloth contain-
ing Confidence Plus from MSA. Follow the directions
on the Confidence Plus container for mixing directions
and recommended times.
Communications System Inspection
1. Inspect the ClearCommand Communications System
modules. Look for cracks or other signs of damage
which could allow contaminants 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
Communications System 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.
