INSPECTION OF EPIC 3 RDI VOICE AMPLIFIER WITH FACEPIECE
1. Before donning the facepiece, inspect the RDI Voice Amplifier
housing for damage such as cracks, chips, discoloration, corrosion,
missing or loose parts, or burned or melted components.
2. Inspect the Mounting Bracket for damaged, missing, or loose
components. Verify that the Mounting Bracket is firmly attached to the facepiece
according to the Mounting Bracket Instructions.
3. Verify the RDI Voice Amplifier is properly installed on Mounting Bracket.
4. Verify operation of the RDI Voice Amplifier. Turn ON unit by pressing and
holding down power button for approximately one (1) full second. Release
POWER button when the LED turns from GREEN to ORANGE.
NOTE
IF THE LED FAILS TO ILLUMINATE, OR IF UNIT IS INDICATING A LOW BATTERY
(FLASHING RED OR ALTERNATING RED/GREEN AND EMITTING A CHIRP) , DO
NOT USE THE RDI VOICE AMPLIFIER. REMOVE THE UNIT FROM SERVICE.
REFER TO THE BATTERY INSTALLATION SECTION OF THIS INSTRUCTION.
USE OF EPIC 3 RDI VOICE AMPLIFIER WITH FACEPIECE
1. Don the facepiece according to the instructions provided with the
complete respirator. Always draw the facepiece firmly to the face to
assure a proper seal. If you cannot achieve a good facepiece fit with the
RDI Voice Amplifier installed, do not use the respirator.
Because the RDI Voice Amplifier is physically mounted on the
respirator facepiece, use care to prevent snags or impacts on the
RDI Voice Amplifier from dislodging the respirator facepiece and exposing the
respirator user to the hazardous atmosphere.
2. Use the RDI Voice Amplifier with a normal speaking voice. Yelling or
speaking too loudly may result in unintelligible voice transmission.
3. After approximately twenty (20) minutes of inactivity (no voice input),
the RDI Voice Amplifier will automatically turn itself OFF. To reactivate,
press the POWER Button.
NOTE
ALWAYS DRAW THE FACEPIECE FIRMLY TO THE FACE TO ASSURE A PROPER
SEAL. IF YOU CANNOT ACHIEVE A GOOD FACEPIECE FIT WITH THE RDI VOICE
AMPLIFIER INSTALLED, DO NOT USE THE RESPIRATOR.
NOTE
BE CERTAIN THAT THE RDI VOICE AMPLIFIER FACEPIECE ASSEMBLY DOES
NOT INTERFERE WITH ANY PROTECTIVE HEAD GEAR.
NOTE
DIRT OR FOREIGN MATTER IN THE CONNECTOR CAN INTERFERE WITH
THE CONNECTION AND/OR PREVENT POSITIVE LOCKING OF THE
CONNECTOR. CONNECTORS MUST BE KEPT CLEAN OF DIRT. SEE CLEANING
AND INSPECTION SECTION OF THIS INSTRUCTION.
WARNING
WHEN THE LOW BATTERY INDICATION
APPEARS (FLASHING RED ONLY OR FLASHING
ALTERNATELY BETWEEN RED AND GREEN
AND ACCOMPANIED BY A CHIRP) CHANGE
THE BATTERIES IMMEDIATELY. FAILURE TO
CHANGE LOW BATTERIES IN A TIMELY MANNER
MAY RESULT IN FAILURE OF THE EQUIPMENT
IN AN EMERGENCY SITUATION WHICH COULD
RESULT IN SERIOUS INJURY OR DEATH.
