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.
