K-x with Toshiba QCC-250 flash

Hi All,
I'm posting a message for the first time.

I have Pentax k-x and have been given an external flash by my father (QCC-250 made by Toshiba) but I can't seem to able to find any information about this flash. I am aware that some old external flash units cannot be used due to high voltage, but I would like to know if anyone has used this or know anything about this flash I appreciate your input.

*I do not have a meter that measures the voltage so I cannot test the voltage output but it uses 4x AA batteries.

It's interesting that if you google "toshiba flash on Pentax", this is the first result.

I once came across a site that lists practically every flash's compatibility, but can't seem to find the link. If I do find it, I'll let you know!

I think this site is what Adam referred to. But it does not list the Toshiba model in question.

The fact that it use 4 AA batteries has nothing to do with the trigger voltage. All flashes have high voltage internally. The question is whether the high voltage circuitry is isolated from the contacts at the hotshoe.

The only sure way to know is to measure the particular flash unit.

Thanks for your reply. I was thinking if I used a remote trigger, would it do the job since it won't have the direct contact with the camera itself?
