La description détaillée de marque:The bloc has conditions:
- manual control;
- automatic control;
- Directorates through cop..
in complement of instruments of ÑÊ3-45 are provided all business hours of bloc.
at the same time the bloc food is carried out from power supply unit of ÑÊ3-45 device
through internal connector.
Âðåæèìå of manual block control can work is autonomous without ïðè-
