Overview
Use external communication (RS-232C) to output the status of the pump to a network system. (The status of the pump cannot be
changed from a network system.)
Ensure that the network system and the pump use the same communication conditions.

Cautions
• When this product is connected with other devices, particularly note the following:
1. When connecting this product with other medical equipment or network system, check its conformance to
IEC 60601-1:2005+A1:2012 (EN 60601-1:2006+A1:2013) and IEC 60601-1-2:2007 (EN 60601-1-2:2007) prior to use in
order to ensure the system safety.
2. When connecting this product with a network system or other equipment, for safety, checking the manufacturer’s
specifications of the equipment is recommended. In addition, use EMI compliant products for the connection cable.
3. When using the external communication function, pay particular attention, as it is more susceptible to the effect from a
radio knife, mobile phone, radio device, defibrillator, etc. Regularly check that this product is operating normally.
4. If connecting with a nurse call, always check in advance with the electrical contractor for compatibility, and connect
with a system for which the connection function has been confirmed. [The functions regarding connection are not
guaranteed.]
5. If connecting with a buzzer or lamp instead of a nurse call, it should be used with a capacity of 12V DC, 1A or less.
• Connection to a network including other devices may cause unpredicted and unacceptable risks for the patient, the user,
or a third person. Be sure to identify, analyze, evaluate, and control those risks.
• Subsequent changes to the IT-network could introduce new risks and require additional analysis.
- Changes to the IT-network include:
1. Changes in the IT-network configuration.
2. Connection of additional items to the IT-network.
3. Disconnecting items from the IT-network.
4. Update of equipment connected to the IT-network.
5. Upgrade of equipment connected to the IT-network.
<Cautions regarding connecting communication cables, communication devices and the nurse call button>
• When using this product’s external communication function to connect a network system and a nurse call button, check the
specifications of the monitor manufacturer, the communication cable manufacturer, and the nurse call button manufacturer,
and further, check safe operation. Further, when connecting to a nurse call button, do not exceed this product’s rating
(maximum 1 A). Also, in order to check the safety of the connections as a system, check their compatibility with IEC 60601-
1:2005+A1:2012 (EN 60601-1:2006+A1:2013) and IEC 60601-1-2:2007 (EN 60601-1-2:2007). Not following these cautions
could result in interference with other medical electrical equipment or breakdown.
Notes
• Operating time using the internal battery is decreased when using external communication while using with the internal battery.
• The specified message (free message function) can be displayed on the pump unit via communication. (For details, contact
TERUMO trained service technicians.)
