Important information regarding batteries

The LapMonitor does not have a switch to switch it off. It goes automaticly in standby when the race or the practice is finished.

Unfortunatly  sometimes the LapMonitor keep staying on. We are currently investigating this issue 

We will provide a firmware update that will solve it and that will also indicate on the smartphone a low battery level. In the meantime we advise you to remove the battery after your day driving session (may be keep a spare charged battery when you're going to the track to not be stuck)

When battery level is low, lap detection does not work properly and you may have missed lap or no lap detection at all

Getting started video

LapMonitor installation

LapMonitor must be installed on the side of the track.

To get the best car detection we recommend to put LapMonitor not facing the sun

If not possible and if needed you can improve the sensitivity using a helmet 

LapMonitor sun

Transponder installation 

The transponder LED must be directed to the direction of the LapMonitor side (not to the front of the car)

Bluetooth speakers/headset

When using Bluetooth speaker, begin of each announcement may be missing, we're working on this issue. To get complete announcement, there are two temporary workarounds:

  • playback built-in LapMonitor App music (IOS only) or your own music while run LapMonitor App
  • connect the speaker using a wireless cable
