It was created on the basis of experience in the combat conditions of captured German field phones FF-33. Outwardly, these devices are very similar, but the location and location of the nodes have little in common.

Power is supplied from one element of the type "3В" or "3С" with a voltage of 1.5 V. Increasing the supply voltage to 9 volts improves the quality of the microphone path.
