          Works well today too  -  especially when the power is off !!!

(1st)  Install the "MOUNTING PLATE" on the wall ...

           

       ... with CONTACTS:  (1),(2) = NIL
                           (3) = white   =  La
                           (4) = brown   =  Lb
                           (5) = green   =  W
                           (6) = yellow  =  E
                           (7) = NIL

(2nd)  The telephone is to SLIP-IN from top-to-bottom ...

       ... and can be SLIPPED-OUT,
       when the LOCK (see ARROW !) is PUSHED-UP with a pen.

The VOLUME of the BELLS is variable with the KNOB on the right REAR.

(3rd) You want it LOUDER for your workshop ???
      EXPERIMENT  with  the  E X C E N T R I C A L  MOUNTED  BELLS
      to VARY THE BELL-DISTANCES !!!
