Re: Osborne-Hoffman 2000E receiver problem

[John Sowden <jsowden@xxxxxxxxxxxxxxxxxx>]

Before your last comment regarding the buzzer,my thought was that the
receiver ring detect circuit is not working.  If the buzzer is connected
across the phone with, with applicable capacitor or course, the receiver
may still not be detecting ring, just the buzzer is working.  Check the
no. of rings to answer in programming.  Meter the phone line on ringing
to confirm it is 90v AC (approx.).  Switch the phone lines to confirm
that is is the receiver, not the phone lines.
Trace the wiring from the coil of the line seizure relay, backwards,  to
see if there is a hardware issue re: the relay not seizing.  If there
are duplicate circuits for each phone line, compare the circuits with a
meter to determine the difference.  If the receiver uses line cards,
swap them.

These are the ones that jump out at me.  As you dive in, you might find
other related issues,

John
