Setting Nurse Call RS-232 Polarity
N-600x Operator's Manual
The nurse call function needs to be tested after it has been set up in
your facility. The nurse call feature should be tested whenever setting
up the N-600x pulse oximeter in a location that uses nurse call. If an
attached O
M
sensor is not connected to a patient, the monitor
XI
AX
display reads zeros and the monitor remains in the Pulse Search Mode
for 5 seconds, then the monitor displays [ - - - ] (3 dashes) in the
%SpO
and pulse rate display. One way to test the nurse call function
2
is to create an alarm condition (for example, sensor disconnect) and
verify that your facility's nurse call system is activated.
The nurse call polarity can be set to a positive signal (NORM +) on a
monitor alarm condition or a negative signal (NORM -) on a monitor
alarm condition.
1. With the monitor in the normal monitoring mode, press the
SETUP softkey.
2. Press the NEXT softkey twice and then press the NCALL
softkey.
3. Press the NORM + softkey OR press the NORM - softkey.
4. Press the EXIT softkey.
