05 | CHARGING THE INTEGRATED BATTERY
Slide the On/Off switch (5) to the position OFF. Open the rubber cover of the Micro USB port (8). Insert the Micro USB plug of the USB
charging cable into the Micro USB port (8) and connect the hearing protector to your PC. While charging, the LED indicator (9) lights up
red. After the hearing protector is fully charged, the LED indicator (9) will turn off.
06 | PROPER SIZE AND INSERTING INTO EAR
To find the proper size of foam ear pads, make sure that the hearing protector is turned off: On/Off switch (5) = OFF.
Now select the best size (S, M or L) of foam ear pads (1) and attach them to the two earphones (1).
Hang the hearing protector around your neck and pull out the earphones.
To insert into the ear, roll and compress the foam ear pad (3) between your fingers. Place the earphone into your ear and hold in place
for about 10-15 seconds to allow the foam ear pad to expand and to seal within your ear.
CAUTION Only a proper insertion of the foam ear pads ensure firm hold and secure hearing protection.
After use press the retraction buttons (4) to retract the earphones.
07 | TURNING ON/ADJUSTING THE VOLUME
To turn on the hearing protector slide the On/Off switch (5) to position ON. The LED indicator (9) lights up blue.
You will hear a beep tone, which indicates that the earphones are ready for operation and which mode is selected:
1 beep tone = Outdoor mode
For outdoor use, with a shorter compression time.
2 beep tones = Indoor mode
For indoor use, with a longer compression time (e.g. to avoid echo).
To switch between the modes, press the volume control buttons +/– (6+7) at the same time for approx. 1 second.

ADJUSTING THE VOLUME

When you switch on the hearing protector, the volume is pre-set to level 5 (+ 3 dB).
Press the volume button + (6) repeatedly to increase the volume in steps up to the highest level 9 (+ 14 dB). Each level will be confirmed
with a beep tone – two beep tones indicate that highest level 9 is reached.
Press the volume button - (7) repeatedly to decrease the volume in steps down to the lowest level 0 (silent). Each level will be confirmed
with a beep tone – two beep tones indicate that lowest level 0 is reached.
To turn the hearing protector off, slide the On/Off switch (5) to position OFF.
NOTE When the device is in the OFF position, the hearing protector will still provide passive hearing protection.

CLEANING AND STORAGE

Never use aggressive cleansing agents or benzine to clean the foam ear pads. Use e.g. a brush to remove skin particles or dust. For
coarse dirt we recommend a soft, slightly damp microfiber cloth to clean the outer parts. Before cleaning, turn off the hearing protec-
tor. Store the hearing protector and the accessories in a dust-free, dry and cool place. This device is not a toy – keep it out of reach of
children. Keep away from pets.
