Yes, sensors use a double nut method to lock the sensors. This is superior to the more common grub screw as grub scews tend to fall out, are fiddly and fill with dirt making them difficult to remove. Additionally if someone is determined to try and screw them off the grub screws will destroy the thread on the valve stem.
In normal mode press and hold the centre button, do not release when it beeps, wait until it turns off. You will need to contact us via the website to get a manual sent to you by email.
What they don't tell you in the instructions is that on standard rubber valve stems the weight of these things will make them flap around damaging your rim and eventually self destructing. You need to fit a solid valve stem. A known problem that is not communicated.
This is very rarely a problem with our system as our sensors are the lightest on the market. I personally have been running sensors on rubber stems for 10 years and over 65kmiles. It is possible that extremely long stems may have a problem and especially some systems which have much heavier sensors may have a problem but we have had practically no feedback about rubber stems being a problem from our extensive customer base.
