Start-Up and Use

To change an existing alarm limit, first enter the viewing mode

for that value, as described earlier in “Viewing Current Alarm

Limits.” Once the value you wish to change is displayed, press

the Adjust Up or Adjust Down button to adjust the value as

needed.

Alarm Limits Changed Indicator

If alarm limits are changed from the NPB-290’s power-on

defaults, a decimal point appears after the displayed value, during

patient monitoring, or when alarm limits are viewed. The

decimal point remains on the digital display until the NPB-290 is

turned off or the limit is returned to its default value.

Adjusting Audible Alarm Silence Duration

WARNING: Do not silence an audible alarm or decrease its

volume if patient safety could be compromised.

Alarms can be silenced for a preset period called the audible

alarm silence duration. The audible alarm silence duration

begins when you press and release the Alarm Silence button.

If an alarm condition occurs while the alarm is silenced, the alarm

will not sound until the alarm silence duration has ended.

Note: An additional press of the Alarm Silence button

reactivates the audible alarm.

If the alarm condition is still present or a new alarm condition

occurs after the alarm silence duration has elapsed, an audible

alarm sounds.

The power-on default audible alarm silence duration setting is in

effect unless it is changed. The power-on default set at the

factory is 60 seconds. This default setting can be adjusted by

service personnel as described in the NPB-290 service manual.
