N-180 Pulse Oximeter Service Manual
These monitors are manufactured in a domestic and an international
configuration. The domestic version uses standard English markings; the
international version uses symbolic markings. Except where there is a clear
need to distinguish between monitor versions the single term monitor applies
to either version. ・
The domestic version (N-180) operates on 110-120 VAC and the international
version (N-180E) operates on 220-240 VAC. There are also differences in the
way controls are marked. Because of the different operating voltages, the
following electrical components differ.
* Transformer
* AC inlet
* Fuse
The parts listings in Section 9, Parts List, distinguish between the models
where such distinctions are needed.
The physical and operational characteristics of these monitors are completely
described in the respective operators manuals. These manuals and other
publications that apply to operating and servicing the monitor are described
in the following paragraph.
