1. Caller information was not transmitted properly. Check with your telephone
company to see if there is a problem with your phone line.
Since our special design will always retain your stored call records, we
encourage you to disconnect all the telephone cords and adapter; and then
reinstall the unit step by step per this instruction manual before you ask for
service.
SPECIAL NOTE: The call records will not be erased when the adapter is
disconnected. A special E2PROM design allows the unit to always retain your stored
call records after you disconnect the adapter
IN CASE OF POWER FAILURE
