TED transmitter missed a couple of start pulses

A customer reported that he missed a couple of start impulse transmits during an all day high school track meet. Otherwise the day went normally. Random missed impulse transmissions are usually the fault of external forces. Usually radio interference from other sources. Make sure your TED transmitter is at least 3 meters (10
feet) from officials or coaches with walkie talkies. Mount it on a tripod with the built in threaded bar or use the velcro strap to mount to a tree or pole. The SM8 pistol transducer comes with a very long cable for this purpose. Like wise get the receiver away from the table where you work and outside or away. The ALGE TED system should be monitored during the day for signs of dying batteries, etc. The receiver will start to emit an off color tone when the transmitter batteries die. Stop the race. Change batteries. Turn both TX and RX off and on again. Resume. Start the day with fresh brand name alkalines and you really should have no problems.
