USER’S INSTRUCTIONS

BASIC LINE: ACTIVATING THE HEARING 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 following the instructions (figure C): Unscrew the battery

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)

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 radio 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.

Adjusting the volume during a call

Operational Description Wireless World - Supreme

version 060920

Adjust the conversation volume by briefly pressing the centre key (O) (figure D). When switched on, the

volume starts at the same setting as when it was last switched off. The volume can be adjusted in four

steps.

Voice-activated calls

This feature requires that you have recorded voice-activation commands on your mobile phone. (It is

recommended that you record your voice-activation commands using the microphone on the hearing

protector.) Press the PTT button (figure I) briefly, wait until your mobile phone answers with a beep tone

(this may take a few seconds). Speak your voice command into the microphone. Note! Some mobile

phones don’t send the beep tone when it is time to speak the voice command.

Receiving and ending calls

When your mobile phone rings you will hear it in the hearing protector. Answer by pressing the PTT button

(figure I). You end a call by pressing the same button. A brief tone confirms that the call has ended.

Call divert

If your mobile phone rings while you are having a conversation, or if you are unable to answer the call,

press and hold the PTT button (figure I) for 3 seconds. Two brief beeps will confirm that the call has not

been taken. Note! The “call divert” feature does not work on all mobile phones. Please refer to the user

manual for your mobile phone for more information.

LED LIGHT (figure I)

Your hearing protector is equipped with a LED light. To activate the LED light press the + and – buttons at

the same time, to inactivate the LED light press the + and – buttons at the same time. The LED lights

automatically shouts off after some minutes.

Note! If your hearing protector is connected to a mobile phone or communication radio with Bluetooth you

will hear the sound on your right speaker. If your hearing protector is connected to a mobile phone or

communication radio with the 3,5 mm audio input you will hear the sound on your left speaker.

TECHNICAL FACTS ABOUT BLUETOOTH®

Bluetooth® technology operates in the ISM band (Industrial, Scientific, Medical) at 2.45 GHz. The

frequency range, 2400–2500 MHz (2.45 GHz), is unlicensed and generally freely available all over the

world. The data transfer rate with Bluetooth® is around 25 times higher than with a standard 28.8 kb/s

modem, and the system is capable of carrying speech in full duplex. Interference from other radio

transmitters in the same frequency range is countered by the random and rapid frequency changes of

Bluetooth® technology (1600 frequency jumps/second).

Range: approx.10 m/33 feet (0 dBm), Transfer rate: 1Mbit/second, Output: 1mW (0dBm).

The Bluetooth® word mark and logos are owned by the Bluetooth® SIG, Inc. and any use of such marks

are under licence. Other trademarks and trade names are those of their respective owners.

MAINTENANCE

The outside of the muff and the cushion can easily be cleaned with soap and water. Earmuffs and in

particular cushions may deteriorate with use and ageing and should be inspected regularly for cracks and

leakage. The cushions are filled with foam or gel and are replaceable. Worn or damaged parts are easily

replaced (fig B). Use only hygiene kits from the manufacturer, designed for electronics, order number

SOR60089 or SOR60092 . The hygiene kit should be replaced at least twice a year for standard use to

ensure that the noise attenuation performances are maintained. This product may be adversely affected

by certain chemical substances. Further information should be sought from the manufacturer.

The user must ensure that the hearing protector:

– fits properly and is adjusted and maintained in compliance with our instructions

– is used all the time in noisy environments

– is inspected regularly to ensure good condition.

If the above recommendations are not adhered to, the protection afforded by the earmuffs can be severely

impaired. Moisture may occur inside the hearing protector muffs if used for long periods. To avoid long

term affects of moisture on the electronic components it is recommended that the acoustic inserts are

regularly removed to allow the muffs to dry, eg, overnight (figure B). When removing the cushion and

insert take great care not to touch the electronics board or cables. Changes in position of cables could

cause disturbance in the system. Do not subject the hearing protector to rough handling, which can

damage the electronics.

The earmuffs must not be immersed in water!

STORAGE

When the hearing protector is not in use, the headband/neckband should not be extended or the cushions

compressed. Keep the muffs dry and clean and keep them in normal room temperature. Do not allow the

hearing protector to lie in direct sunlight. If the product is to be stored for a longer period it is

recommended that the batteries be removed from the battery holder to prevent damage.

If the above recommendations for the hearing protectors are not adhered to the attenuation values

ability could deteriorate considerably.

LIMITED TROUBLE SHOOTING/CARE ADVICE

If the electronics cease to function it may be easy to rectify the problem. Please check the following:

• Replace the batteries with new ones.

• Ensure that the batteries are correctly fitted in the hearing protector.

• Ensure that the battery plates make good contact with the batteries.

• Ensure that the battery plates have not become coated with verdigris.

• When the hearing protector is worn for long periods, moisture may build up inside the earmuffs.

To prevent long-term effects of moisture on the electronic components we recommend that the inserts and

cushions are removed regularly to allow the inside of the earmuffs to dry out, overnight for example. If

these measures do not help, consult the point of sale.

WARNING!

• When exceeding the specified limits a risk of hearing impairment exists.

• This hearing protector may not be used to restore entertainment.

• These earmuffs reproduce ambient sound electronically. The user must check the function before using

the product. If distortion or other fault is detected, follow the instructions for changing and maintenance of

the batteries. If this does not help, consult an authorized agent.

• The function can deteriorate in step with discharging of the battery. In normal use, the estimated life of

the batteries is about 150 hours (Basic Line) and 600 hours (Pro Line). For version 75318 is the estimated

battery life 110 hours (based on one hour talk/ eight hour use)

• The estimated A-weighed sound level inside the muff, with consideration taken to attenuation values

(table 2, 3 & 4), shall not exceed 82 dB(A).

• Remember that hearing protectors generally can shut out ambient sound, such as warning shouts,

alarms and other important signals. Be therefore extra cautious of your surroundings when wearing

hearing protectors.

• The integrated microphones for reproduction of ambient sound increase safety considerably in your daily

work. Note! It is possible to disconnect the level dependent function, which means that warning signals

Operational Description Wireless World - Supreme

version 060920

and warning shouts would be much more difficult to hear. To minimize the risk of accidents we therefore

recommend that the level dependent function be connected as far as possible.

• The output signal from the level dependent function can exceed the actual external sound level.

• The level dependent function may deteriorate in rain or moist conditions and the user should therefore

be aware of the possible deterioration. If deterioration occurs, immediately allow the microphones in the

hearing protector to dry (with open muffs for 24 h) until the function is fully restored.

• The fitting of the hygiene covers to the cushions may affect the acoustic performance of the earmuffs.

• The symbol on the product indicates that this product may not be treated as household waste.

Instead it shall be handed over to the applicable collection point for the recycling of electrical and

electronic equipment. By ensuring this product is disposed of correctly, you will help prevent potential

negative consequences for the environment and human health, which could otherwise be caused by

inappropriate waste handling of this product. For more detailed information about recycling of this product,

please contact your local council office, your household waste disposal service or the shop where you

THE FOLLOWING SUPPLEMENTARY INFORMATION APPLIES TO SORDIN SUPREME, ONLY IN

USA/CAN:

Tested according to ANSI Specifications, ANSI S3.19-1974

Information required by E.P.A:

The level of noise entering a person’s ear, when hearing protection is worn as directed, is closely

approximated by the difference between the A-weighted environmental level and the NNR. Example: The

environmental noise level at the ear is 92 dB(A). The NNR is 23 decibels (dB). The level of noise entering

the ear is approximately equal to 69 dB(A).

CAUTION:

For noise environments dominated by frequencies below 500 Hz, the C-weighted environmental noise

level should be used. Improper fit of this device will reduce its effectiveness in attenuating noise. Although

hearing protections can be recommended for protection against harmful effect of impulse noise, the Noise

reduction Rating (NRR) is based on the attenuation of continuous noise and may not be an accurate

indicator of the protection attainable against impulsive noise, such as gunfire.
