On/Off switch for the microphone

The microphone can be switched on and off with the switch »Mic.–OFF–Mic.« (Fig. 3/a) at the bottom of

the right-hand headset muff. Three switch positions are possible. However, communication can only be

performed after the connection setup.

Middle position »OFF« (receiving): The headset microphone is switched off. You can only receive.

Front switch position »Mic.« (transmitting and receiving): The headset microphone is switched on.

You can speak into the microphone as long as you hold the switch in this position and simultaneously a

message is being received. After releasing the switch the switch returns to the middle position »OFF«.

Rear »permanent« switch position »Mic.« (transmitting and receiving): The headset microphone is

permanently switched on. You can speak into the microphone and simultaneously receive a message.

(transmitting and receiving) can be performed after the connection setup has been effected.

Commissioning and operation

3.1

Putting on the headset and adjusting the microphone

a. Put on the headset. Take care for a perfect comfortable fit. Only when the ear cushions are properly

located around the ears the best noise attenuation of the ear muffs is provided. Adjust the height of

each ear muff equally on both sides while holding the head band down until the ear cushions have a

tight and comfortable fit. The head band should sit straight and comfortable on the top of the head.

For hygiene reasons we recommend the use of the washable sweat absorbing cotton pads (see

section 14) on the ear muffs. These are pulled over the ear cushions and are for the purpose of

wear comfort and hygiene.

CAUTION

Do not »twist« the flexible gooseneck. Do not carry the headset by the gooseneck.

Use the microphone only with a windshield.

b. Adjust the flexible gooseneck so that the microphone is located at a distance of approx. 5 mm

(0.2 in.) in front your lips. Optimum speech transmission with the best possible noise compensation

is then provided.

3.2

Wearing the headset with the additional head strap

In the event of rapid body movements or extreme body postures or if you are using a protective helmet

the headset can be additionally secured on your head by means of the head strap (Fig. 2/a). Put on the

headset, fold the head band (Fig. 2/c) to the rear and wear the head band as a neck band. Ensure that

the head strap and neck band are tautly seated.

3.3

Switching on and automatic connection setup

a. The headset is switched off, if the On/Off switch and volume control (Fig. 3/b) or the On/Off switch

(Fig. 3/d) is in position »OFF«. Switch on the headsets by means of the On/Off switch and volume

control (rotary knob) or the On/Off switch.

After switching on a high beep tone is audible in the headsets. After further 5 to 10 seconds a high

double-beep tone sounds, indicating the completion of synchronization between the headsets. Now

the headsets set up automatically a connection between each other. When the connection is set up

a high beep tone sounds in the headsets and the headsets are ready for duplex communication.

The microphone must be switched on in order to speak, if the headset is equipped with a

microphone switch (see sections 2.7, 2.8).

b. On speech reception adjust the speaker volume for your headset by means of the On/Off switch and

volume control (rotary knob).
