20s with SR10 problem
Occasionally while having my 20s connected to my SR10 connected to multipoint pairing (second phone) my radio transmissions come across like a Cylon robot - very distorted. The only solution is to reset everything - turning it all off and then on again. I had that problem too with my SMH-10. Cannot seem to find a triggering event when it occurs, but it has been very annoying over the years. Used different radios without success in eliminating the problem. Everything is paired correctly and I have done both factory resets and hard resets for both units in trying to eliminate the problem. The problem is frustrating as it is occasional in nature but crops up in the most unopportune moments making things very unreliable. Anyone with similar problems or a solution?

Same issue, multiple units, also seems random. Funny that my buddies talk about this audio distortions as 'cylon mode' and agree that power cycling the SR10 is the only way to reliably fix the issue. Digging through the tank bag w gloved hands to hit the tiny button on top plus the big button is frustrating and dangerous.
Sena -- I volunteer to help debug. I happen to be a wireless hardware engineer. Who is your BT vendor? CSR? Broadcom?0 -
Andrew -- I never heard from Sena on this. I'll have to read up on the "reverse pairing" concept. You are saying that you could not reliably reproduce the problem, but you did have the problem in the field?

Hi all, I am having the same intermittent garbled transmissions with my sr10 hooked to my DWO-5 helmet. I believe I am tracking this down to a possible thermal problem with the sr-10. Just did a long ride from California to Boise, and in the cool weather it took 5 hours to fail, coming back it was hot and it failed in 6 minutes. Cycling power will bring it back for a while. Has anybody looked into a thermal related problem with this transmission issue?

Thanks for your input andrew. As part of this thread, I think you mentioned that one of your friends did the reverse pairing but also had the transmission problem. Did I read that right, I think you were talking to Ken and brian. I'm going to try using a heat gun and slowly warm up the sr10 and if I get a garbled voice I'm going to put it on blue Ice and see if it goes away, it just seems that as the temperature increased, the failure mode increased. I've asked Senna about this, but I'm still waiting for the reply as far as whether it could be a thermal problem or not. I'm not sure they'll own up to it if it is a thermal problem, because it probably either means a heat sink problem or components internally are getting too warm, and that means a hardware recall.. I'll let you know what I find!

Thanks Andrew for your feedback. Good to hear that Sena gave you that information as well. Only problem is I like music, navigation and CB because I lead a lot of bikes with cbs.. I'll let you know about my thermal test! Do you know how often this problem occurs on the sr10? Like sooner or later everybody has his problem or do I just have a marginal unit.

Hi guys, I did a check for any thermal issues with the SR-10, I performed the following test:
I did a heat soak test, lasting a half hour, with an initial SR-10 case temperature of 72 degrees and slowly heated the unit to between 130 and 140 degrees. I let it soak for 10 minutes. I continued to transmit during the complete test with no voice degradation during transmission.
I suspect my problem is most likely not heat related. I have a Sena tech suggesting some resets and updates with my SR-10 and DWO-5 Sena helmet transceiver.

Thank you Andrew, that is a very good data point.. I have updated and reset both my helmet and sr-10, and we'll see what happens when I have a long ride...

Well Andrew, I believe I tracked the problem down to the pigtail cable.... No problems since I changed it out.....

You described the cable problem exactly! Exactly what happened, and exactly how I figured out the problem. It will be interesting to see if the robot voice situation occurs again, I'm hoping not. Thanks for your help!

As a follow-up, I have used the sr10 with my ham radio VX 7r, and of course it has a different pigtail, and I never had the robot voice. Possibly indicating it's not the sr10 unit itself.
