The AF280 is a pretty robust flash unit. I would do as Don suggests and fire the unit 10 times or so by hand to see what happens. I also think the PZ-1 is pretty robust and will not be destroyed by any faults in the AF280.
When I have not used the AF280 for months, I do notice an initial slowness to recycle after flash. This goes away after some use as the capacitors are re-formed to accept a charge. Since I know this happens, I make sure to fire the flash on full manual 5-6 times with older batteries. Then, I change to a fresh set of batteries and am ready to go with re-formed capacitors and better recycle times. Regards, Bob S.
