Checking Voltage, Flash and Camera GX-10

hey all
i was wondering the the voltage of the samsung gx-10. couldnt find it in my manual. i got a vivitar flash series 1 for pentax cameras (so samsung too) the other day and i forgot all about checking the voltage to make sure it wont damage anything until someone reminded me before it came in the mail. so now i have it and i am waiting to hook it up until i make sure it does not damage anything. someone told me the hot shoe should have insulators in it so it wont damage, is that true? and is it just when i hook it up through a cable?

thanks in advance

You absolutely need to check the trigger voltage of the flash. The hot shoe offers no protection to the cameras electronics. The only way to protect the camera from a high voltage flash is with a "safe-sync". It is a little box that slides into the hot shoe and reduces the voltage to a safe level. I think there are a couple of different companies that make them.

Cobalt...You can check voltage fairly easily using a high resistance meter on the flash unit synchro output socket. If you don't trust yourself, take it to a local electronics repair shop. I'm sure they will help. AFAIR input trigger voltage for GX10/GX20 should not be more than 24V.

Try the following website - getting a bit crusty now but might be useful.
