| Cliff, This is not normal and we carry out 
a 24 hour feedback test here on every unit to ensure that the loops do not 
decay over time. This problem is probably related to the 16MHz crystals in your 
unit not being quite close enough tolerance. We have found replacing the CRYSTAL 
Audio Codec chip will also cure the problem. Where are you and how would you like 
to get this problem fixed? Andy @ Trace 
Elliot.
