[ RadSafe ] pulser manual request

[Robert Atkinson]

Hi Marco,
DON'T PLUG IT IN UNTIL YOU HAVE REPLACED THE INTERNAL BATTERIES!.
These units have an unregulated mains supply and rely on the battery to limit the maximum voltage. If the batteries are dead or missing the voltage can rise high enough to fry the hard to get U6A9958 divider chips. 
 There is a modification to add a 5V regulator. see http://tech.groups.yahoo.com/group/GeigerCounterEnthusiasts/files/Eberline%20MP-1%20Power%20Supply%20Mod/
I'll look to see if I have a manual at home.
 
Robert Atkinson G8RPI.
