I was starting a photo shoot today and had my CyberSync hooked up to my sekonic light meter to get a reading. All of a sudden my flashes were going off uncontrollably. I put my CyberSync on my Nikon D200 and now it won't fire my flashes. Any ideas on what happened?

bad battery. As the battery gets low, it can rapid transmit. Before that, however, it will give you a low battery indicator with three rapid red blinks of the LED when activated. CSRB and CSRB+ do the same.

When you replace the battery, be sure to orient it in the proper direction: + side goes down in the drawer.

Thanks for the reply. Where do I get a new battery from?

Many superstore are carrying it.
Same for pharmacies and Radioshack stores.

It is a model CR2450. I got my last one at Walgreens, but most stores that sell batteries should stock them, WalMart, Kroger, Radio Shack, etc.

Thanks.

Thanks TS,

I just got my CST and am using sunpaks 383, 333 and an auto 30DX. I was doing my first initial tests with 2 strobes at about 5 feet apart with no problem. Then i too them to about 2.5 feet apart and thats when the rapid fire light show occurred for me. Could the close proximity of the strobes cause the rapid fire light show and then burn out the new CR2450 batt in the CST? or did I just get a bunk batt sent to me?

I upgraded to the cybersyncs hoping to eliminate this very embarrassing and wasteful rapid fire light show that would occurr with my ebay cheapo's. Please let me know if i'm hopeless in finding a frugal solution to a reliable radio trigger/strobe combo??

First, check the indicator the LED on teh transmitter gives you when you press and release the test button. It should only blink red once. If it multi blinks or does not blink, then its a bad battery. The lights rapid firing would not "burn out" a battery, the battery would power teh transmiter that generates the signal for the lights, or there is some issue that is causing the lights to fire, by-passing the battery. Also, look at your recievers LED. Without generating a signal from the transmitter, do they blink green. If so (and they should if powered on) is it one slow green blink, or three rapid blinks? If rapid blinks, the remotes are in repeater mode, which can cause issues in close proximity. Press and hold the test button until the blink switches to a single slow green blink. Also, look at the recievers when the rapid firing happens. Do the LED's blink red when this happens? If so, a signal is being generated from somewhere. Try switching frequencies to see if you can dial out of the problem range.

Being sunpaks, what cord (or method) are you using to connect the recievers? Are all lights firing at once or randomly from one to another?
