White or red, submitted with confirmation
Each referee uses the controls for their assigned position. Decisions are confirmed by the server and revealed together after the third submission.
An operator clock everyone can follow
Start, pause, resume and reset the attempt timer from the assigned operator browser. Displays render the authoritative server deadline and recover the current clock when reconnecting.
Review before your first event
Try the interactive sample, check your venue connection and rehearse with the release candidate. Formal sport and device validation remains part of the paid-launch requirements.
Set up the official positions
Create the competition as weightlifting, add a platform and issue three referee invitations. Each device is assigned a position by the organizer. White and red controls are shown for this sport; powerlifting reason cards are omitted. Create separate invitations for the operator, jury and read-only displays so each participant receives only the controls needed for their role.
Check the display before the session
Open the venue display on the actual competition screen. Review its size, browser zoom, timer visibility and any uploaded competition logo. Ask each referee to submit a rehearsal decision and confirm that colors appear together after the third accepted submission. Reset deliberately through the operator controls, then verify that all devices follow the new attempt.
Plan the venue connection
Test the Wi-Fi and internet path from the referee seats, jury table and display computer. Phones should have sufficient power and screen settings appropriate to the session. Reconnection restores the current server state; it does not make an internet outage disappear. Rehearse with the release candidate and agree the sport-specific operating procedure before any pilot event.
