The telephone instrument you have can be used on the NEC Electra Professional Level I, and the Level II systems (and under some conditions the NEAX 2000 series). Codes for features are somewhat different based on the system. It is possible that your phone is in "Do-Not-Disturb" if other phones on your system actually ring when they are called via the intercom (on the Level I and Level II systems, initial intercom ring is a system wide setting). The cancel DND code is: Level I system: with telephone idle, press <FNC>, dial 60, press <FNC>. Level II system: with telephone idle, press <FNC>, dial 69, press <FNC>.
It is also possible that your ring volume is very low. To adjust, press <SPKR>, dial 601, then adjust volume using the up/down keys at the bottom of the phone (press <SPKR> when finished. If your system is programmed to access an outside line when you press <SPKR>, you will need to press the <INTERCOM> button first.)
If your system is set for voice intercom, people calling your phone can make it ring by dialing a "1" after your intercom number.
If you do all this and your phone still won't ring on incoming calls, let me know and we'll have to go into system programming to correct it.
