Changing the Time on the Tadiran Coral with Version 8 or Lower Software

From any attendant telephone:

1.    With the handset on-hook (hung up) dial 188.  The date and time will show on the display.
2.    Enter the time with the keypad using 4 digits, e.g., for 2 p.m. enter 0200.
3.    Enter 2 for AM or 7 for PM.
4.    Enter 11 to confirm.

The display should say clock confirmed and the time will change after a few seconds.

If this doesn't work, you may have Version 9 or greater software.  Click here.
