Ahh, found the following which might explain what i meant better:
Beep! Beep! Beep! If at any time while testing or diving, the DS 125 beeps continuously it's not set right or it's broken. The DS 125 should only beep on two occasions --- when firing at full power and sometimes when turning the strobe off and then on. And in these two occasions it should only beep one time.
If the strobe is beeping continuously and you are using the manual controller, make sure the manual controller is not set between settings. A possible "fix" with the manual controller is to set the DS 125 strobe to 1/8, 1/4, 1/2, or full instead of TTL. Then control the power with the strobe power settings --- the manual controller settings have no effect when the manual controller is used this way. If this works, keep on taking pictures and get the controller and strobe checked by Ikelite when it is convenient to you.
Another cause of continuous beeping is flooding of the DS 125. So if it starts beeping during a dive and the above "fix" doesn't work, open the strobe with care when you are out of the water to avoid possible problems with battery acid leakage.
