Default Alarm Limits
Default alarm limits are in effect when the N-200 is turned on.
There are two sets of default alarm limits, one for adults and
one for neonates as shown in Table 3.
Table 3: Default Alarm Settings
Alarm Limit

Setting
Adjustable
Range
High oxygen saturation 100% 95% 20–100
Low oxygen saturation 85% 80% 20–100
High pulse rate 140 bpm 200 bpm 20–250
Low pulse rate 55 bpm 100 bpm 20–250
Note: When the operator turns the N-200 off and back on
again, alarm limits return to default values.
To determine whether the default alarm limits are set for an
adult or a neonate, press the HIGH SAT button immediately
after turning on the N-200. If the instrument is set for an
adult, 100 appears in the OXYGEN SATURATION display; if
it is set for a neonate, 95 appears.
Changing From Adult to Neonatal Alarm Limits
To change the adult/neonatal setting, move the adult/neonatal
alarm switch UP to change the setting to adult default limits,
DOWN for neonatal default limits. Turn the N-200 off and back
on to reset default settings (refer to Table 1).
Note: When changing settings, the N-200 must be operating
on AC power for the change to be implemented.
