Federation Football Rule Change 2019

The NFHS has approved the Ready for Play Timing Rule Change. Here’s how to update your Ready-Ref Play Clocks.

Field Clocks

If your transmitter has Serial Number 1320xxx, we are able to convert your field clock system to the new 25-40 second rule. This conversion will cost $20 for each transmitter, plus $15 for return shipping.

To make this change, please send us the following:

• The transmitters
• The circuit board (located near the top in the back of your field clock)
• The antenna (attached to circuit board)
• Note with your address, phone number, and a message about what you want changed
• Your payment ($55) (If you live in Ohio, there will be an additional $2.90 tax.)

NOTE: Before removing the circuit board, please take a photo of the board for your own reference.
