02 CAUTION
In order to avoid hearing disorder, make sure that the earphones fit properly in your auricles (please refer to chapter 06). Wear the earphones throughout the whole period of noise duration. Should the foam ear pads start to show cracks, do not use them anymore. After prolonged use, the evidence of cracks is a sign of material fatigue, which is considered a natural wear out. Replacement foam ear pads are optionally available from DÖRR.
The DORR E-Silence GS-31 is an active hearing protection to wear around the neck. The soft foam ear pads optimally adapt to the auricles and reliably protect against noises such as gunfire. Desired ambient sounds, warning signals or conversations remain audible. Perfect for hunters, riflemen, security authorities and in all areas of application where hearing protection is required.

3 Foam ear pad
4 Retraction buttons
5 On/Off switch
6 Volume control +
7 Volume control-/Mode button
8 Micro USB port
9 LED indicator
10 Flexible rubber joints (allow folding)

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 arphone 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.
08 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.
09 | 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 protector. 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.
