Some of the circuit monitor’s advanced features, such as onboard data logs
and alarm log files, can only be set up over the communications link using
SMS. SMS versions 3.12 and higher support the CM4000 device type.This
circuit monitor instruction bulletin describes these advanced features, but
does not tell how to set them up. For instructions on using
SMS,refertothe
SMS online help and the
SMS-3000 Setup Guide,
which is available in
English (63220-060-200), French (63220-060-201), and Spanish (63220-
060-202). For information about related instruction bulletins, see Table 1–2
