US SEMI is aware of certain SG12ST and older SG21 machines that seem to not have the recent saber timing despite being upgraded. US SEMI believes the upgrade programming mechanism or device used to update the machines has some kind of fault that caused the machine to not be upgraded when it should have been. We believe that you can determine if your machine is faulty by setting it to Saber, turning it off, and turning it back on again. A correctly upgraded machine will not have the audible alarm that indicates the B-C connection is open. A faulty machine will sound the alarm. The lights will indicate the open condition on both working and faulty machines as normal. This was a change put into the software with the timing upgrade and can be used as an indication if the upgrade was successfully applied. The presence of a sticker is not an indication of whether the machine has correct timing. US SEMI has NO indication that any forfeiting of stickers has occurred.
US SEMI believes that it may be possible to fix the fault by repeatedly applying the "flash" programming sequence until it is successful. This would have to be done by a factory authorized technician, and would require the machine to be sent to the technician.
We would stipulate that anyone bringing an older machine that they think did not re-program properly and proof of purchase from Absolute Fencing or Ted Li could have them re-re-programmed at the Absolute Fencing Gear booth at the USA Fencing National Championships and July Challenge or the 2018 October NAC at no charge, but that lacking proof of purchase they would pay the standard fee.
We recommend that faulty machines not be used for tournaments in which rolling points will be awarded. Use for other tournaments is at the discretion of the organizer.
