What equipment must be at the scorer's table before the game?

The rules list this equipment for the game:

• game clock, scoreboard and shot clock
• a stopwatch or suitable visible device (not the game clock) for timing time-outs
• 2 separate, distinctly different and loud signals, one for the shot clock operator and one for the timer
• the scoresheet
• player and head coach foul markers
• team foul markers
• the alternating possession arrow

The scorer's table and its chairs are placed on a platform. The announcer and/or statisticians, if present, can sit at the side of and/or behind the scorer's table.
