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

The product must be fitted with 2 standard alkaline batteries 1.5 V AAA/LR03. The use of rechargeable batteries 

such as NiMH 1.2 V or NiCd 1.2 V will reduce the operating time. The battery compartment is full integrated in 

the hearing protector 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 compartment. Make sure that the polarity of the 

batteries is connected to the correct terminals (+) and (–) in the product (figure B1). Refit the insert and press 

on the cushion. Make sure that the bulge of the cushion is facing towards the bottom. Carefully check that the 

inserts and the cushion are correctly fitted so that noise reduction is not impaired. Note! Always switch off the 

product before replacing batteries.
PRO LINE: ACTIVATING THE HEARING PROTECTOR/BATTERY INSTALLATION/REPLACEMENT (figure C)

The hearing protector requires two standard alkaline 1.5V 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! Always switch off the product before replacing batteries. Make sure that the batteries polarities are 

inserted correctly and secure that the battery lid is completely tightened.
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, (+/-)

Short presses on the volume keys adjust volume of the ambient sound, i.e., 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 the product off 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 the product will be switched off. Press any key to delay the switch-off by 

a further 4 hours.
HEADBAND VERSION
Folding the hearing protector (figure E)

Extend the headband as far as it will go. Then press the top of the headband to fold the hearing protectors 

together.  Make  sure  that  the  cushions  lie  flat  against  each  other  and  that  there  are  no  creases  in  them. 

Note! Do not store the hearing protectors 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 

spectacle frame, 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 adjusted up or down the headband to adjust for a 

firm, comfortable fit. This safety requirement is satisfied for the sizes:

NECKBAND VERSION
Use and fit (figure G)

Brush excess hair back and out from beneath the cushions with your hand as much as possible. With the 

neckband behind the head, place the ear cups so as to completely enclose the ears. Be certain that the 

cushions seal tightly against the head with no interference from objects such as respirator headbands 

or spectacle frame, in order to obtain the best performance. Adjust the net over the head so the hearing 

protector don’t fall off. Note! Do not pull the net to tight because it will affect the cushions seal, the net shall 

only hold the hearing protector in place, not pull the hearing protector upwards. This safety requirement is 

satisfied for the sizes:
