What was found
(CAN) DURING THE TROUBLESHOOTING OF ANOTER ELT SYSTEM. IT WAS DISCOVERED THAT THE ELT REMOTE SWITCH WOULD TURN THE ELT ON PROPERLY BUT WOULD NOT RESET THE SYSTEM WHEN SWITCHED BACK TO "ARM". THE REPLACEMENT OF THE ORIGINAL PROBLEM SWITCH WITH A NEW ONE IDENTIFIED THE SWITCH TO BE THE PROBLEM. FURTHER TESTING CONFIRMED THAT THIS SWITCH WAS DEFECTIVE. THE SWITCH IS BEING RETURNED TO THE MANUFACTURE FOR TESTING.
