Bicron Surveyor M meter

[OldGrayOwl]

I have a Bicron Surveyor M survey meter that has stopped working. I replaced the battery, but I don't get any response.Anyone have a schematic for this device?
Thanks,

You may have to remove all of the batteries then install the new ones to allow the instrument to reset. Ran into this with a Bicron Micro REM meter.
