NEC VERSA V User Manual page 131

If the telephone company requires information on what equipment is connected to
their lines, inform them of:
n The telephone number to which this unit is connected
n The ringer equivalence number (see the modem label)
n The USOC jack required.
n The FCC Registration number (see the modem label).
The ringer equivalence (REN) is used to determine how many devices can be
connected to your telephone line. In most areas, the sum of the RENs of all
devices on any one line should not exceed five (5). If too many devices are
attached, they may not ring properly.
Modem Service Requirements
If the modem malfunctions, all repairs should be performed by NEC Technologies
or an NEC Authorized Service Center. It is the responsibility of users requiring
service to report the need for service to NEC Technologies or to an NEC Author-
ized Service Center.
