Notice
1.
During a long programming session, it is highly recommended that you periodically save the
system data to the SD Memory Card. You can think of system data as stored in RAM, whereas SD
Memory Card as stored on a hard disk. If the PBX undergoes a sudden power failure or system
reset for some reason, all the system data in RAM will be lost.
To save the system data to the SD Memory Card, (1) click the "SD Memory Backup" icon before
resetting the PBX or turning off the power, or (2) exit the Maintenance Console so that the PBX
starts automatically saving the system data.
2.
When the PBX is initialised, not all data is taken from the SD Memory Card. The data for present
status of extension FWD/DND buttons is taken from battery backup memory in the PBX.
3.
The PC will not perform any shutdown operation, or enter the power-saving system standby mode
while the Maintenance Console is connected to the PBX.
To perform either of the operations above, first close the connection to the PBX.
CAUTION
Do not remove the SD Memory Card during access to it. Doing so will damage the system data, and in
the worst case, damage the SD Memory Card.
