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 3: 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.
