to exit the short NAM- programming mode.

NB:

The Number Assignment Module (NAM) is programmed through the telephone keypad. There are two NAM-programming modes available; the short and the long. The short programming mode is all that is required in most cases. The long programming mode is required if a value set by the short mode is not desired. Either mode may be used stand-alone, or the short mode can be used to set up most of the values and then the long mode can be used to make any changes desired. To enter either of the two NAM programming modes, press and hold down the FCN key while entering a specific series of digits. You must enter the digits within ten seconds. In each programming step, you can either keep the displayed setting or value, or you can change it.

a. To go to the next step, without changing anything, press #. b. In some steps, you can “toggle” a setting from ON or OFF, or vice versa. To change the setting, press any numeric key. In other steps, you can replace a displayed value. To replace a value, enter the digits on the numeric keys. If you enter a wrong digit, you can erase it by pressing FCN CLR.

Pressing * key restores the original value in the display.

Press # to store new setting/value and go to next step.

Press END/PWR in any step to leave the NAM-Programming mode. If you have changed anything in a step, you must store the setting by pressing # before pressing END/PWR.
