Introduction

The ZM-940PA transmitter transmits ECG, respiration, SpO2, NIBP and pulse waveform from a patient to a Nihon Kohden monitor for continuous monitoring. The transmitter can change channels when connected to the QI-901PK channel writer. The front LCD displays SpO NIBP, pulse rate, pulse waveform amplitude, electrode condition mark, battery condition and NIBP measuring mode and interval.

Read the operator’s manual for the receiving monitor together with this manual before operation.

CAUTION

• Do not use the same channel for different patients. Otherwise, two patients’ data will be lost due to mutual modulation interference, or another patient’s data may appear on the receiving monitor screen.

• Do not use transmitters of adjacent channels in a hospital. Otherwise, radio waves from one transmitter affect the receiver of the adjacent channel’s transmitter and there may be interference.

• Do not use the same transmitter on more than one patient at the same time. Do not connect different sensors on different patients to the same transmitter.

NOTE

• To prevent interference between channels, assign a channel administrator in the hospital and only he or she should manage channel assignment.

• Use Nihon Kohden parts and accessories to assure maximum performance from your instrument.

• For stable signal reception, it is recommended to use a diversity antenna system on the receiving monitor. Otherwise, spike noise from transient fading of electric field strength (for example, people moving) may interfere with the transmitter signal and may be mistaken as an arrhythmia on the receiving monitor.

• NIBP cannot be measured on a neonate. (ECG, respiration and SpO monitored on a neonate.)

Changing the Transmitter Channel

The channel of the transmitter can be changed. The optional QI-901PK Channel Writer is required.

WARNING

The following action must be taken to properly receive the transmitter signal of the correct patient on the receiving instrument. Otherwise, there may be signal loss or signals may mix causing a serious accident, such as monitoring a different patient.

• Assign a channel administrator in the hospital and only he or she should manage channel assignment on his or her responsibility.

• The channel administrator must manage the channels in the facility so that there is no signal interference.

• When the transmitter channel is changed, the channel administrator must check that the channel on the receiving monitor is also changed and the signal is properly received.

• The channel administrator must replace the channel number label on the transmitter with the new one after changing the channel.

NOTE

The software version of the QI-901PK channel writer must be 02-01 or later to change the channel on the ZM-940PA transmitter.

To check the transmitter channel, refer to “CHANNEL” in the “Changing System Setup Settings” section.
