Cautions
• 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.
• 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.
Notes
• TERUMO cannot guarantee the connection.
• If an alarm sounds, this product sends signals to the nurse call for approx. 5 seconds.
• If an error is displayed, this product sends a continuous signal.
