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)
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.
