Connecting the instrument
1. Set rotary interval switch (5) at "0".
2. Unscrew the plug (8) in the socket of
the motor winder R3 (match markings
on the plug and on the motor winder)
and secure it by screwing it home.
The connection between the RC LEICA R
electronic control unit and the motor win-
der R 3 can be extended up to a distance of
100m.
