Ask event staff to activate your logger, then scan the QR label with your phone camera. The label opens LapBrain. Sign in or create your LapBrain account, check the event and logger number, and tap Claim rental day. You do not need a Trackside account or the same email address you used to book. If your installed app cannot open the rental link, open it in your phone's browser to claim. Update the app to use rental links directly in the native app.
You receive Pro for the event's local calendar day. Every session recorded that day keeps Pro access permanently, even if you upload it after the event. Your ordinary monthly Pro session pass remains available on its usual schedule.
If LapBrain says the logger is not ready, ask event staff to activate it. If you have already claimed a rental for that day, ask staff to replace the logger under your existing rental. Claiming a second rental will not give you another Pro day. Returning or replacing the logger preserves your access.
