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.
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.
Moving the boat to site was done by Boat Haulage Ltd. It had to come about 80kms along secondary roads as it was not allowed on the motorway. That took about 4 hours starting at 2300 and arriving on site at around 0300. The crane supplied by Hi-Lift Cranes arrived at 0630 and was set up by 0710. The lift only took about 13 minutes. The crane was a 55 tonner. The boat was weighed during the crane in at exactly 3000kg. I had setup the cradles the previous afternoon after having measured their spacing at the boat's original building shed and then leveling them out approximately on my, not quite level, site. Turned out to be pretty level in the end but I will straighten it up later. More videos to follow on moving it out of the shed it was built in (I know back to front, right? By request).
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.
