Fig. 3 Headset with level-limited ambient sound reception

In the case of external sound levels of over 85 dB(A) the sound level emitted by the ASR speakers in

the headset muffs to the ear is limited to a maximum of 85 dB(A). The overall noise attenuation of the

headset is, however, limited to passive noise attenuation of the headset muff.

Operator control

Described below are only the operating control differences relating to external sound reception.

Switch on the ambient sound reception by means of the rotary knob »ASR« (Fig. 3/b) on the rear side

of the right-hand headset muff and adjust by means of this rotary knob the desired volume for the

ambient sound reception. The ambient sound reception is switched off in position »OFF«.

It is possible to use the headset for ambient sound reception only via the separate On/Off switch and

volume control »ASR«.

Headset with radio set

connection

Two communication circuits are realizable with the

additional radio set connection (example Fig. 4).

Both the base headset and the standard headset

can be equipped with a radio set connection.

Connection to the radio set is effected via a radio

set adapter which consists as a rule of the

following parts:

– Inline PTT button with fastening clip on the rear

side (Fig. 4/b)

– Connection cable with socket for connection to

the headset (Fig. 4/a)

– Connection cable with radio set plug (Fig. 4/c)
