To make full profit of the solenoid and the synchronization of this electric powered mechanical trigger, the precise location of  the solenoid in its mount on the lensboard is required.  Loosen the clamp screw in the solenoid mount so that the solenoid release may be moved vertically. Connect the release link with the shutter release lever. Set the shutter at its top speed and cock it.

Connect the solenoid A with the SOLENOID OUTLET on the battery case by means of a connecting cord: 

household to male bi post-. Catalog number 2703= 17"

Set Circuit Control on N

Press main switch on battery case 

If the solenoid is in the right position, the shutter will fire.

You may try this out by moving the solenoid in the clamp until the shutter immediate reacts on the main switch.

Now connect the contact post on the shutter D to the SHUTTER OUTLET on the battery case with the shutter cord: 

Pressing the main switch activates the solenoid which opens the shutter which on its turn fires the flash.

Make sure to set shutter controls (c) first:  M, F, or X
