WARNINGS
This headset will only provide the hearing protection as indicated by the SLC80
rating when it is maintained in good working order and fitted correctly. Other
factors affecting the noise attenuation characteristics of the headset are items
which affect the seal between the Ear Cushion and the head e.g. thick framed
glasses, protective clothing such as balaclavas, thick beards, etc.
It is vitally important that you give consideration to the sound output produced
by the earphones in the headset itself. You must ensure that the volume setting
of the radio, or other connected device, is adjusted to a safe listening level as
there are no output limiting devices included within the electronic circuitry of the
headset.
For correct care of this Headset, you must refer to the Care and Maintenance
Instructions on page 7.

FITTING INSTRUCTIONS
The purpose of a Headset is to:
1. Protect your hearing
2. Provide electronic communications
Correct fitment of the Headset to your head is vital for maximum
hearing protection and to optimise communications ability.

NB: The Headset Ear Cups must be fitted over your ears
covering and enclosing them completely
The Headset should be fitted so that the horizontal axis of the Ear Cup bisects the
approximate tip of the nose of the wearer. This usually means the Headband of the
headset will be located directly above the ears, however the headband may be
adjusted slightly forward or rearwards for maximum comfort. See figure D below.

STEP BY STEP USER GUIDE
NOTE: The Headset is intended to be worn with the microphone
and cable on the left side of the head.
STEP 1 Fitting the Microphone Boom
Fit th d on

Ro
Ea
P

e Microphone Boom assembly to the mounting socket locate
Left Side Ear Cup (cable side).
tate the collar clockwise whilst screwing onto the socket on the
r Cup. Firmly finger-tighten only.
artly bend the boom to where you estimate your mouth will be,
ensuring the Yellow Dot is facing towards the mouth.

STEP 2 Fitting the Headset
Holding the Ear Cups as shown, slightly stretch
Headset apart just enough place over your head (see
Figure 2.0). Release and make sure the Ear Cups sit
evenly over your ears and cover them completely.
Move the Headset so the Headband is sitting
correctly and comfortably on your head (see again
Figure D).
NB: Do not over-stretch headset
Figure 2.0
STEP 3 Adjusting the Ear Cups
a) Figure 3.1 below illustrates how the black Adjusting Slides can be moved up or
down on the Headband. This allows you to adjust the position of the Ear Cup to
provide better comfort and a more efficient seal on the head to keep out noise.
b) With one hand, hold the Headband steady at the top of your head (as shown in
Figure 3.2). Holding the Ear Cup with your other hand, move it up or down to find
the best position so that the Ear Cup completely seals onto your head, around your
ear. No part of the ear should be caught between the Ear Cushion and the head.
Make similar adjustments for both sides and ensure Headset fits snugly.

Figure 3.1 Figure 3.2
STEP 4 Ensuring Ear Cups seal against your head
Placing one hand against each Ear Cup, firmly
push both Ear Cups inwards against your head and
hold for 2 seconds. This action moulds and helps
the Ear Cushions to form an efficient seal against
the head around your ears which improves both
comfort and hearing protection.

STEP 5 Adjusting the Microphone for maximum clarity
(5a) ADJUSTING DISTANCE
Microphone must be positioned
as close to the lips as is comfortable.
This provides better voice clarity.
See Figure 5.1.
Maximum Distance
From lips = 5 mm
Figure 5.1
(5b) ADJUSTING POSITION
Adjust windsock (Microphone) to be
directly in the centre of the mouth
opening. Ensure that the Yellow Dot
is facing toward your mouth.
See figure 5.2.
NB: Project your voice loudly and
clearly into the microphone
Figure 5.2
STEP 6 Checking electronic operation
Check Earphones (speakers)
You should hear sound from your radio in both Ear Cups. If this is not the
case, check the connection to the communications device or that the
device is operating properly
Check Microphone
Check that the speech you are attempting to transmit is reaching the
intended person, clearly.
Caution: Do not set the volume level of the radio, or other connected, device too
high! See paragraph 2, Warnings on page 2.

CARE & MAINTENANCE
We recommend that your headset be cleaned regularly, by wiping with a damp
sponge containing mild soap and water. Pay special attention to the Ear Cushions
to ensure removal of perspiration and skin oils which can reduce the service life of
the Cushions. These areas of the Headset that come into contact with the wearer’s
skin should also be regularly disinfected using isopropyl alcohol wipes.
When cleaning DO NOT allow moisture to enter the Ear Cup assemblies or any part
of the Microphone Assembly. UNDER NO CIRCUMSTANCES SHOULD YOU
IMMERSE THE HEADSET IN ANY LIQUID.
To maintain the noise attenuation properties of the Headset, the Ear Cushions (see
Figure 6.0, item 5) should be replaced every six months and the inner foam
assembly (see Figure 6.0, item 4) every twelve months. More frequent replacement
of these items may be required if the Headset is being used under extreme
conditions. Inspect the headset regularly for signs of damage or wear.
7
IMPORTANT: This Headset should not be stored in direct
sunlight or temperatures above 55 degrees C. as distortion
of the Ear Cushions may occur.
PARTS REPLACEMENT (See items 1 – 5 pictured in Figure 6.0)
The LEATHER HEAD BAND COVER (item 1) is simply wrapped around the Head
Band with the edges overlapping so that the Velcro seam can be evenly pressed
together. To remove the cover, pull the top overlap away from the bottom at the
Velcro seam.
To remove and replace MICROPHONE BOOM (item 2) see the “Fitting Instructions
- Step 1” and simply reverse the process by unscrewing, counter clockwise, the
knurled nut at the base of the Microphone boom.
The EAR CUSHIONS (item 5) are removed by placing one or two fingers inside the
Ear Cup and under the Ear Cushion’s rigid plastic plate. Hold the Ear Cup firmly
with the other hand and pull the Ear Cushion plate until it pops out of the Cup. The
new Cushions just clip back into place under the lip around the circumference of the
ear Cup opening. Ensure the Ear Cushion plate has seated and clipped-in properly
before use.
The INNER FOAM ASSEMBLY (item 4) also supports the Earphone and care
should be taken not to damage the wiring. With the Ear Cushions removed,
carefully take out the foam wafer and pull apart the two bottom layers where the

wires enter. Carefully remove the Earphone. Place the Earphone into the new foam,
remove paper cover and press both layers together. Install foam back in cup and
replace Ear Cushion.
The WIND SOCK (item 3) is the black foam cover for the Microphone at the end of
the Microphone boom. To remove, simply pull the Wind Sock off the end and gently
stretch and pull the replacement Wind Sock over the Microphone again.

NOISE EXPOSURE
There is considerable medical research data now available which clearly demonstrates a
link between the loss of hearing in humans as a result of exposure to noise. The factors
which contribute to this loss of hearing are many and complex, and as the Headset user
you should discuss your requirements with suitably qualified professionals to ensure that
the headset you have selected is suitable for the type (frequencies) of noise & level of
noise you may encounter as well as the period of exposure. The chart below should be
read in conjunction with AS/NZ standard 1269.
