USER’S INSTRUCTIONS

BASIC LINE: ACTIVATING THE HE ARING PROTECTOR/REPLACING BATTERIES (figure B)

The product must be fitted with 2 standard alkaline batteries 1.5 V AA. The use of rechargeable batteries
such as NiMH 1.2 V or NiCd 1.2 V will reduce the operating time. The battery holder is full integrated in
the earmuff and does not have any buttons. To change the batteries, follow the instructions below (figure
B). Start by pulling the earmuff down as far as it will go (figure F). Remove the cushion by pulling it straight
out (figure B). Insert the batteries in the battery holder. Make sure that the (+) and (–) terminals on the
batteries are the right way round (figure B1). Refit the insert and press on the cushion. After replacing the
batteries it is important to check carefully that the inserts and the cushion are correctly fitted so that noise
reduction is not impaired. Turn the cushion so that the bulge is at the bottom.

PRO LINE: ACTIVATING THE HEARING PROTECTOR/BATTERY INSTALLATION/REPLACEMENT
(figure C)

The hearing protector requires two standard alkaline 1.5 V AAA/LR03 batteries. Rechargeable batteries,
for example NiMH 1.2 V or NiCd 1.2 V, should not be used as they may significantly reduce the operating
time of the product. The batteries are protected from moisture and dirt by our unique battery compartment.
You can easily install and replace batteries by followi ng the inst ruc tio ns (figu re C): Uns c rew the batt ery
cover. Insert the first battery with the (–) pole facing inwards. Shake the earmuff lightly so that the battery
falls into place inside the earmuff. Then insert the second battery with the (+) pole facing inwards. Refit the
battery cover. Note! Make sure that the batteries are inserted the right way round to ensure the correct
polarity (+/–).

FUNCTION KEYS (figure D)
On and off, (O)

Press key (O) to activate the electronic functions. To switch off, hold the same key (O) pressed in for 1
second.

Volume adjustment, (+/-)
Volume of the ambient sound is adjusted by short presses on the volume keys, ie, down (–) or up (+). The
volume starts in the mode at which it was switched off. The volume can be adjusted in four steps (Basic
Line) or five steps (Pro Line). The output signal from the sound reproduction system of the product will not
exceed known risk levels for damage to hearing. Sound via the speakers is limited to maximum 82 dB(A)
equivalent sound level.

Battery–saving mode

This product is provided with a battery economy function to ensure maximum life of the batteries. The
function automatically switches off the level dependent mode after 4 hours if no key is activated during this
period. To restart, push the key located at the middle of the keypad (O). About 2 minutes before automatic
switch-off a tone will be heard as a warning that sound will be switched off. Press any key to delay the
switch-off by a further 4 hours.

together (fig. E2). Make sure that the cushions lie flat against each other and that there are no creases in
them (fig. E3). Note! Do not store the earmuffs in this positions.

Use and fit (figure F)

Brush excess hair back and out from beneath the cushions with your hand as much as possible. Be
certain that the cushions seal tightly against the head with no interference from objects such as respirator
headbands or arms of glasses, in order to obtain the best performance. With the headband over the head,
place the ear cups so as to completely enclose the ears. The ear cups may be slipped up or down the
headband to adjust for a firm, comfortable fit with the headband over the crown of the head.

This safety requirement is satisfied for the sizes:

Connection

75301, 75302, 75302-X, 75318 & 76302 has one input, 3.5 mm, for connecting an external acoustic
source, eg.: communication radio, hunting radio, mobile phone, etc. We recommend that you connect the
angled jack plug to the earmuff as this gives the most secure connection and is least obtrusive.

75328 & 76328 have a down lead with a connector to connecting an external acoustic source, e.g.:
communication radio, hunting radio, mobile phone, etc.

Refer to the operating instructions for the external audio equipment to ensure that it is correctly connected.
The impedance of the Supreme Pro is 32 Ohms. The circuit must not be subjected to a signal greater than
5 volts to prevent permanent damage. The maximum input signal must not exceed
75301: 134 mVrms
75302, 75302-X & 76302: 399 mVrms
75318, 75328 & 76328: 242 mVrms
(rms = root mean square of signal strength) to prevent the sound level through the speakers from
exceeding 82 dB(A). Note! Please see Table 1 for more detailed information.

The following supplementary information applies only to version 75318:

We have moved one step further into the Wireless World. You can now link your mobile phone or
communication radio to your hearing protector without cables and hands-free leads that interfere with your
work. The range is around 10 metres (33 feet) for interference-free communication (the range is affected
by wall construction, road vehicles, vegetation, etc.). Certain features depend on which brand of mobile
phone or communication radio you use. We therefore recommend that you read carefully through the
user’s instructions for your mobile phone or communication radio before using it with the hearing protector.
Any equipment you want to use with Supreme WW must be compatible with Bluetooth® wireless
technology (version 1.1 or later), and provide support for one of the Bluetooth® Headset or Hands-free
profiles (up to version 1.00 m).

TO ACTIVATE THE BLUETOOTH® SYSTEM

The first time you use your mobile phone or communication radio with Supreme WW hearing protector you
will need to connect the units so that they recognize each other. Note! This requires that you have a
mobile phone or communication radio equipped with Bluetooth® technology!

Connecting your mobile phone and hearing protector:

Switch on the hearing protector by pressing the key (O) in the middle of the keypad (figure D). Press and
hold in the Push-To-Talk (PTT) button (figure I) for 10 seconds until you hear a “dong” tone in the hearing
protectors. This sends a signal to all units with Bluetooth® technology within a distance of 10 metres.
Switch on your mobile phone, search the menu and follow your mobile phone instructions on how to
search for and receive signals from Bluetooth® units. When your mobile phone has found “WW Headset”,
select it and key in the PIN code 0000. The “dong” tone should stop and your mobile phone and hearing
protector are now connected and ready to use! Note! Some mobile phone need that you connect the
hearing protector by choosing the hearing protector in your mobile phone after you have complete the
pairing process.

Connecting your communication radio and hearing protector:

Switch on the hearing protector by pressing the key (O) in the middle of the keypad (figure D). Press and
hold in the Push-To-Talk (PTT) button (figure I) for 10 seconds until you hear a “dong” tone in the hearing
protector. This sends a signal to all units with Bluetooth® technology within a distance of 10 metres. Switch
on your communication ra dio and follow your communication radio instructions on how to search for and
connect Bluetooth® units.

BOOM MICROPHONE (figure J)

The hearing protector is equipped with an electret microphone on a hinged boom. The microphone is
noise compensating, which ensures very good voice perception even in noisy environments. Note! It is
important that the head of the microphone is positioned close to your mouth, about 2-5 mm from your lips,
in order for noise compensation to work well. To prevent interference from wind noise we recommend that
the accompanying windshield is used.

FUNCTION KEYS (figure D)
Making a call

First make sure that the Bluetooth® function in your mobile phone is switched on. Normally this is indicated
by a symbol in the mobile phone display. (Please refer to the user manual for your mobile phone). Call the
number with your mobile phone as usual. You will hear the call in the hearing protector speakers and you
talk into the microphone attached to the hearing protector. Remember to position the microphone close to
your mouth to ensure that the noise compensation works.
