For some time since we got the SENA SMH10 headsets we had trouble getting them to pair. Tried for so long to use the method from the manual, but have now worked out that the manual is wrong. Tried pushing the same jog dial as we had held for five seconds, then usually ended up turning the units on and off and just pushed jog dials at random until the units spoke to each other.
We've found that if you hold one unit's jog dial down for the five seconds until the "Intercom Pairing" announcement, then to complete the pairing you have to press the OTHER unit's jog dial to establish the intercom pairing. The units don't pair if you tap the SAME jog dial that you held down for five seconds.
The procedure which works on our sets is:
1. Turn on both SMH10 headsets (A and B)
2. Press and hold the Jog Dial on either headset (A or B) for 5 seconds until LEDs of both headsets start flashing red. You will hear a voice prompt saying, “Intercom pairing”
3. Tap the Jog Dial on the OTHER headset (tap B if you held A for five seconds, tap A if you held B for five seconds) and wait until the LEDs of both headsets turn to blue and the intercom connection is automatically established.
We're just using the headsets for rider to pillion conversations and love the units, they were easy to install, they're clear, easy to use, easy to recharge and refit to the helmets. Know they do so much more, but we're perfectly happy just using them as an intercom.
