CHAPTER 1. Overview of MMC Programming
1.3 Cautions in Programming
Programming can be done only while the handset is placed on the phone in idle state.
Full programming can be done on any digital LCD phone.
Only station level programming is allowed on a phone that does not have an LCD
display.
If the LCD displays an 'INVALID DATA' message while programming, reenter the
correct data.
If no button is pressed for a certain period of time during programming (default is 60
seconds), the phone returns to the idle state from programming mode.
Programming mode halts if the handset is picked up or the Transfer button is pressed
or the phone is unplugged. Any data previously entered in the display is saved.
