Connection
The product has one input, 3.5 mm, for connecting an external acoustic source, e.g.: communication
radio, hunting radio, mobile phone, etc We recommend that you connect the angled jack plug to the
earmuff as this gives the most secure connection and is least interfering. Refer to the operating instruc-
tions for the external audio equipment to ensure that it is correctly connected. The impedance of the
product is 32 Ohms. The circuit must not be subjected to a signal greater than 5 volts to prevent per-
manent damage. If the audio signal level does not exceed:
75301: 134 mVrms
75302, 75302-X & 76302: 399 mVrms
75318: 242 mVrms
(rms =root mean square of signal strength), the sound pressure level inside the hearing protector will
not exceed 82 dB(A). Note! Please see Table 1 for more detailed information.
THE FOLLOWING SUPPLEMENTARY INFORMATION APPLIES ONLY TO VERSION 75318:
We have moved one step further into the Wireless World. You can now link your external communica-
tion devices like mobile phones or communication radio to your hearing protector without cables 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 product you use. We recommend that you carefully read the user's instructions for your
product before using it with the hearing protector. Any equipment you want to use with the hearing pro-
tector must be compatible with Bluetooth® wireless technology (version 1.1 or later), and provide sup-
port for one of the Bluetooth® Headset or Hands-free profiles (up to version 1.00 m).
ACTIVATE THE BLUETOOTH® SYSTEM
The first time you use your external communication device with the hearing protector you will need to
connect the units so that they recognize each other. Note! This requires that your equipment is equip-
ped with Bluetooth® technology!
Connecting your communication devices and hearing protector:
Switch the hearing protector on by pressing the key (O) in the middle of the keypad (figure D). Press
and hold the Push-To-Talk (PTT) button (figure I) for 10 seconds until you hear a "dong" tone in the
hearing protectors. This will send a signal to all units with Bluetooth® technology within a distance of
10 metres. Switch on your product, search the menu and follow your instructions on how to search for
and receive signals from Bluetooth® units. When your product has found "WW Headset", select it and
key in the PIN code 0000. The "dong" tone stop and your product and hearing protector are now con-
nected and ready to use! Note! Some mobile phone require that you connect the hearing protector by
choosing the hearing protector in your mobile phone after you have complete the pairing process.
BOOM MICROPHONE (figure J)
The hearing protector is equipped with an adjustable electret microphone. 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
