Tuning Instructions
General
All tuning operations of the NSW-4 are carried out using the service soft-
ware. The service software turns the phone into the locals mode, in which
the phone can be outwardly controlled via the MBUS interface.
Tuning is based on the software communicating with the D/A and A/D
converters of the phone. In some instances the phone processor will also
calculate the required correction parameter.
The tuning values of the phone reside on the EEPROM. The contents of
the EEPROM can be read by the service software and saved as a file.
This is advisable when there is need to retain that information, e.g. in
view of replacement of the circuit. The program also enables writing the
default parameters on the EEPROM, in which case all tuning steps should
be carried out.
During tuning, proceed as follows:
