Panasonic KX-TD500 System Reference Manual page 163

[Note]
a) When you start up the system after installation, the Operation Switch (MODE) should be set to "5" or
"6".
• No.5 .... When you program the system data based on the factory programmed default values.
• No.6 .... When you program the system data without the factory programmed default values.
b) When system programming is finished, the Operation Switch (MODE) should be set to "0", "1" or "2".
• No.0 .... The system enters to on-line mode if the current system programming data has no logical
errors. When the system detects a logical error, the programming screen which informs the
invalid data and an error message appears on the maintenance device.
• No.1 .... The system enters to on-line mode after executing pattern check of RAM which has the system
programming data. When the system detects an error, the system programming data will be
defaulted. When the system detects no errors, the system executes the procedure of No.0.
• No.2 .... The system enters to on-line mode after executing pattern check of RAM which has the system
programming data. The system programming data won't be defaulted even if RAM errors
detected. Then the system executes the procedure of No.0.
c) With System Memory
The system has current system programming data.
d) Without System Memory
The system does not have current system programming data.
e) Off-line
It is available to perform system data programming but call processing and functional test are not
available in off-line mode.
f) Power failure transfer
Connects preassigned CO lines and extensions directly, bypassing the system.
g) After you entered the system administration mode, keep the following considerations in mind when
setting the Operation Switch.
• No.5 .... Current programming data will be defaulted.
• No.6 .... Current programming data will be removed.
