TMG-51-L Telephone-Microphone Headset for Efficient Line Testing

The headset TMG-51-L is designed for operational communication on de-energised lines up to 5 km long, resistance up to 1 kOhm and checking of these lines for short circuit or breakage ("ringing"). The headset is single-eared (with one telephone), left-eared. Design features:
- The microphone is attached to a goose-neck type headband, allowing it to be moved to any convenient position relative to the mouth;
- Combined design of the headband provides a good hold on the phone by adjusting the occipital rigid spring part and the adjustment to the size of the operator's head from size 53 to 60 through the upper strap part;
- The presence of a switch allows the headset not to be disconnected from the amplifier unit during short breaks in operation;
- The headset is adapted to be worn under different types of helmets.
