Don - thank you for your suggestions. It turned out that I couldn't do a Master Reset as the "4" key is the ATT/PRE key as well and that wasn't working. So I resoldered that switch's contacts and was able to do a reset and initialize the eeprom. At that point it passed all part 1 tests. I also want to thank Alan for his suggestion of doing a reset. Onward... This list is the greatest help. 73
