SETUP:
1.
Remove the LOUDMOUTH from its package.
2.
Install a fresh, 9 Volt alkiline battery.
Turn the LOUDMOUTH "OFF" by turning the volume
switch counterclockwise until it "clicks". Remove the
LOUDMOUTH from the SCBA harness or belt.
Loosen the two thumb scews on the back of the
LOUDMOUTH case and remove the battery
cover. Pull up on the ribbon to eject the old
battery and slide in a new battery.
Observe
proper polarity (the same pin goes in first).
Do not force the battery down; if it is difficult to
insert, you may have the battery upside down.
Replace the battery cover and assure that the thumb screws are finger tight (not
tightened with pliers). Inspect the battery cover seal to make sure it is evenly
compressed.
WARNING: Batteries must be changed in an area known to be non-hazardous.
3.
Turn your Loudmouth "ON" with the rotary ON-OFF/ Volume
switch and verify battery condition. Put the unit close to your
ear and listen for a slight hiss. If you can't hear the hiss with
the volume turned up, change the battery before proceeding.
Before moving to Step 4, turn the unit "OFF" and proceed.
4.
Connect the microphone cord to the LOUDMOUTH. Screw it
down finger tight. Do not tighten with pliers.
5.
Mount the LOUDMOUTH on your belt, SCBA
harness, orTurn-Out Coat using the wire bale on the
back of the case.
THROAT MICROPHONE (LMT-2):
Place the Throat Microphone on your neck. Position the Throat Microphone around your
neck. Assure that the cord exits over the top of the Throat Microphone Band, as if it were
pointing slightly forward and up. The Microphone capsule should sit in the small hollow
between the two, large throat muscles. If you place your fingers in the side of your neck and
slide them towards the front, you'll feel a slight indentation at the muscle transition point. Place
the capsule of the Throat Microphone right on the
transition, not on your Adam's Apple.
Operating Tips:
If the Band feels too tight, you may loosen it by
"unwinding" the Band. If it feels too
loose, tighten it by "winding" is closed. For maximum
positioning security, attach the Velcro closure to keep
the Band from loosening.
SAC MICROPHONE (LMT-2S):
Earmark’s SAC Mic sticks to the outside of your SCBA
mask. It works best when attached to a hard lens. Some
masks have speaking diaphragms with protective shields.
The SAC Mic can be attached to the protective material
above or around the speaking diaphragm (but, not the
diaphragm itself). If your mask has a soft lens, the
speaking diaphragm shield may be your best alternative.
Follow the installation steps provided with the SAC
Microphone package.
Operating Tips:
Make certain there are no loose, hard materials vibrating on the SCBA lens. The
microphone “hears” them and broadcasts them as a buzzing sound.
When using the SAC Mic with the Loudmouth Speaker Mic, position the microphone on
the side of your mask opposite the side where you plan to wear the Amplifier (left or
right). This will minimize chances for audio feedback if you turn up the volume.
