Yes, the Wireless Hand Controller can be customized to provide the flags your track uses.
The default configuration is flashing green, yellow and red, solid green, yellow and red, checkered and white flag.
If there are flags your track does not use, the button can be configured with a custom flag and animation. Here are a few of the custom configurations developed for customers:
Customer wanted to eliminate the unused flags to prevent the corner worker from pressing a flag they do not use. This configuration provided four flags, solid green, yellow and red and flashing red. All the other button default to clearing the safety light.
Customer requested the checkered be replaced with the debris flag.
This unit was highly customized to control a Start Light. All the buttons were defined to start different modes of starting sequences.
