Intended Use
General
The ZM-520PA and ZM-521PA transmitter transmits ECG and respiration from a patient to a
Nihon Kohden monitor for continuous monitoring. The front LCD displays ECG, numeric values
of monitoring parameters, messages and battery condition.* It also displays the compressed
waveform and numeric data of the latest 10 minutes.

from a patient to a Nihon Kohden monitor for continuous monitoring. The front LCD
displays ECG (or pulse wave), numeric values of monitoring parameters, messages and battery
condition.* It also displays the compressed waveform and numeric data of the latest 10 minutes.
* Essential performance of this transmitter.
The difference between the ZM-520PA/530PA and ZM-521PA/531PA is the transmission
frequency range.
ZM-520PA/530PA: 608.0250 MHz (channel number 9002) to 613.9750 MHz (channel number
9478)
ZM-521PA/531PA: 1395.0250 MHz (channel number E002) to 1399.9750 MHz (channel number
E398)
1427.0250 MHz (channel number E502) to 1431.9750 MHz (channel number
E898)
The transmitter channel can be changed with a QI-901PK channel writer.
Read the operator’s manual for the receiving monitor together with this manual before use.
WARNING
Do not diagnose a patient based only on data acquired by the transmitter. Overall
judgement must be performed by a physician who understands the features,
limitations and characteristics of the transmitter and by reading the biomedical
signals acquired by other instruments.
WARNING
Do not use the same transmitter for more than one patient at the same time. Do not
connect different sensors from different patients to the same transmitter.
