A 3-function button can be mounted on the entertainment station to call for assistance. The wrist watch receiver can be worn by staff on duty, or the manager who authorizes the payout. When a patron presses the call button, both the wrist watch receiver and the display monitor, located at the servers’ station, will display the machine number or seat number of the patron requiring assistance. Staff can also use the wireless calling system to contact a manager (wearing the wrist watch receiver) when in need of prompt assistance.
