Dear All,
Has anyone got Birtcher medical (Beacon Laboratories) Beamer one (model) service manual. The issue we are facing is that once we press the foot switch both APC and Electrosurgical unit( Valley lab ) should work simultaneously, which is not happening . We have one adaptor interface(RJ11) with a new jack, the wire was connected to 3 and 4 before and after, but on tracing circuit the socket is connected only to 1,2,5,6.
Not able to find what we missed.
