rate: 1 cycle per second).
• Showroom mode does not acvate sleep mode.
• If there is no user acon during 2 minutes of showroom
mode, the animaon will stop and then UI behaves (fake) as
normal mode.
• During the animaon, if the user touches any key, the
animaon will stop and UI behaves as a fake normal mode.
• During fake normal mode, aer two minutes without user

is in showroom mode.
