4.1 SERVICE SWITCH TABLES
The tables that follow describe the functions carried out by the bits and combinations
of bits for each service switch. In order to correctly interpret some of the functions
required, a knowledge of the communication protocol is required. The default values
may undergo some modifications due to both homologation and user's peculiarities.
For this reason, you are recommended to print out the service switches of the facsimile
machine to be serviced, always before modifying them.
