Ncu Parameters - Ricoh M0A0 Service Manual

NCU Parameters

The following tables give the RAM addresses and the parameter calculation units that the machine uses for ringing
signal detection and automatic dialing. The factory settings for each country are also given. Most of these must be
changed by RAM read/write (SP2-102), but some can be changed using NCU Parameter programming (SP2-103); if
SP2-103 can be used, this will be indicated in the Remarks column. The RAM is programmed in hex code unless (BCD)
is included in the Unit column.
