 Hello everyone! Material on identifying counterfeit audio cassettes in
this number simply did not have time, so I will give two useful diagrams -
ki.

 Emergency lighting.
Ifyour chandelier is intended for only one ┌───────│

and also, if you first turn on standby mode - ─┬─ │
then this will extend the life of the lamp (since the lamps └ └
usually burn out due to an inrush current when turned on - / /

Both of the above schemes were assembled by me and work normally.
