New Tickets and sound
When a Waiter sends a Round, its Ticket appears on the kitchen terminal within a moment, as the last of the open Tickets, and the tablet chimes: two short tones. The Ticket also prints, if a printer prints the Station’s Tickets.
The browser lets the tablet make a sound only after someone touched the screen. Until then it says so at the top:

① Tap anywhere to turn on the sound for new Tickets. Tap anywhere on the screen once; the banner goes, and from then on every new Ticket chimes. After the tablet or its browser restarts, tap once again.
The chime is as loud as the tablet: turn its volume up with the buttons on its side. Marking a Ticket done or printing it again makes no sound.
Example: in the morning, the cook switches on K-001 and taps the screen once. At 11:42 Silvia sends Table 4’s Menu of the day; the tablet chimes, and the Ticket is the last card on the screen.
