Vivitar DF-383 charging sound
I have bought a new DF-383 from ebay, but I have a small issue with it and don't know if it normal or I have a bad unit.
Normally when you charge a flash you can hear the high pitch noise for few seconds while it is being charged. But on this DF-383 I hear it also after it is charged - every 14 seconds it probably tries to recharge itself (I hear the noise) for 2 seconds and then is silent for another 14-15 seconds and so on... First I though that the batteries are dying, but it was the same after fully charging the batteries.
So is this normal for Vivitar (or maybe also some other flash units) or I should send the unit back?
