Hello everyone,
Thanks to all who replied to my help request. This is the outcome .......
I realised exactly what was happening just after my posting. Due to my bad
translation of the Siemens CHR531 manual and, dare I admit, some
considerable investigation work; - the "STO" pushbutton must be pressed, and,
whilst this is done you must press the "RCL" pushbutton and then release them
both to store the displayed Frequency.
Without pressing the "RCL" button the memory ICs do not get addressed with
the memory location as determined by the front panel, 1 to 12, location
memory switch setting. 772. S42045-E716-S5.
The clue is in the RCL STO truth table on circuit S42045-E723-A1-*-7411
Frequenzspeicher. Under (speichen) STO, the logic condition for storage is
shown with BOTH the STO and RCL pushbuttons pressed together.
The Memory battery has no effect whatsoever on the STO and RCL process,
that solely preserves the frequency memory when the power is off..
I just wish that 50 years ago I had been allowed to take German instead of
Classical Latin at school!
Needless to say I have yet to find a Premium Receiver handbook printed in
Latin - yet.
Regards,
Pat G3YFK
