11. MASTER AND BACKUP MASTER ALTERNATION
The Backup Master Terminal can be changed to be used as the Master Terminal for an accident that the Master
Terminal becomes down, etc. And the Master Terminal can be changed to be used as the Backup Master when
it comes back from repair, etc.
To switch from the Backup Master Terminal function to the Master Terminal function:
1 Disconnect the master terminal from the line.
2 When other terminals are in registration operation, finalize and cashier sign-off, or Cashier Key to OFF
operations should be performed.
Since a transmission error occurs at this time, an inquiry job should be completed.
3 Change the backup master terminal address from 2 (BM) to 1 (M). (Therefore, the backup master terminal will
function as the master terminal.)
Refer to TERMINAL ID SETTING (Submode 77) on Chapter 4.
4 Delete the backup master terminal from the terminal connection table on the master terminal.
(Reprogramming is required.)
Refer to TERMINAL CONNECTION TABLE SETTING (Submode 69) on Chapter 4.
5 Download the terminal connection table.

The following files and data are lost when the master terminal goes down.
