functions.
Basic Definitions
Password is set to 0123 and is used to access basic parameter settings (see Table 3: Parameter settings). The
set-up programming is normally done in the factory during manufacturing of the telephone sets. The factory
settings can be loaded into the EEPROM (see Figure 6: Memory allocation for external EEPROM).
PIN code is default set to 1111 and is used by the user to protect certain user settings (see Table 5: User
programming with PIN code). The PIN code can be changed by the user.
Default settings are shown in
bold
.
Program procedures are entered with the [PG] key. Pressing any invalid key or going on-hook during programming
will abort the program mode and no changes will be stored. Ending a program procedure by pressing the [PG] key
will store the changes and exit the program mode.
