Help with cybersyncs

Hello everyone, I have one cst and two crsb's. I went to use them the other day and it wouldn't work. I took the battery out of the cst plugged it back in and I got one pop out of it and that was it. I did the same thing over again still one pop and that is it. Is this a battery problem or the transmitter? Thanks for the help.

Try changing the batteries in your CSRB's?

They seem to be fine the light keeps blinking on them.

That is how my CST acted when the battery got low. It also started triggering the receivers on it own if I got it too close to them. Replaced the battery and all was fine. My battery lasted about 1 year.

Unfortunately, that's no sure indicator.

Replace your batteries.

Did you change the cst battery? They have them at wal-mart in the camera section, TLE and possibly in the jewelry section. If you did replace it what were the results?

what lights are you using them with? That may seem like a silly question. The company i work for had a major problem with the early csr's and genesis 400 lights. One trip then they wouldn't work until the light was turned off and back on. Not very practical. Buff replaced them all with csrb's and they work much better if not perfectly in certain situations. The csr+ units seem to work fine with the genesis 400s as well.

As everyone has already stated. Batteries are usually the main reason this happens. I have found sometimes that "plates" in the batter compartment need to be pulled out a bit. I few times I had it were it wasn't making good contact with the batteries and so no go. Take a look at that and see if it helps. If anything else, PCB customer service is second to none, I'm sure they will do whatever it takes to help you out!

Paul C. Buff even says in the paper manual that they will fire inconsistently when the batteries are close to being dead. Just replace them, trust me

yep... this is likely a problem with the battery in your trigger. not nearly as convenient to replace the coin batteries as it is a AA. one of the reasons I'm planning on transitioning to the Cactus V5 system.

Yeah. What PCB doesn't tell you, is what he considers to be 'close to dead'.
Believe me, it's not what you and I think 'close to dead' is.

Guys, voltmeters are NOT accurate in these devices. And they are poor at determining remaining charge as well. ANY small electronic device does not have a reliable battery monitor. And batteries are so inconsistent with how they discharge, in different temperatures, that there's no way, nor any reason, to get a super-accurate meter. Thats why sometimes when you take it out and put it back in, it shows some life, if only for a short while. Even expanded scale voltmeters aren't totally accurate.
If there's ANYTHING weird happening, changing the batteries is always the first step. AND, if it still happens, change them again, as sometimes you get bad ones, or old ones.

turns out it was the battery even though the reading said it was still good. oh well works good now

Well, the first time I had this problem, my trusty Fluke 87 - that's gotten me through years of broadcast engineering work - showed the voltage of the 'near dead' battery to be 2.91. Now, in the years I spent behind the scenes in television, and some on concert touring circuits, any device that we had that ran on similar voltages would keep on running well, even if the batteries metered at 2 or even a little less. So, no, in my world - and in my experience - 2.91 volts isn't 'near dead'. No "super-accurate" meters required.
A design of this application should be a little more robust with its battery life. That said, I still like and use my Cybersyncs.

I would almost bet that if you had 5 different cybersyncs, they would all act differently to the same battery when the voltage got low. Possibly because of mass production, looser tolerances, who knows.
My point is, batteries are the first thing to change if something seems odd.
