AC Power Indicator This green LED illuminates whenever AC power is applied to the unit. 17. Battery Indicator This green LED illuminates whenever the unit is operating on battery power. The LED will flash when the battery requires charging. When the LED begins flashing, approximately 30 minutes of battery time remain on the Accutorr Plus NIBP (20 minutes on the Accutorr Plus NIBP with Trend Screen and 10 minutes on the Accutorr Plus NIBP with Trend Screen and SpO2). 18. NIBP Connector This connector is used to attach specified NIBP hoses. 19. On/Standby Key This key is used to activate the unit, enabling it to begin taking measurements. The unit does not have to be “ON” for the internal battery to charge. However, the unit does need to be plugged into an AC receptacle for the battery to be charging. 20. Memory Full Indicator This LED indicator flashes when 80 - 99 of the 100 available entries of trend are used. This LED is on continuously when 100 are used. Delete measurements manually using the DELETE INFO. key or the unit will automatically delete the oldest measurement for the current patient. NOTE: The unit will also automatically delete data that is 24 hours old.

21. Delete Info. Key Press the Data Scan key to enable the Delete Info. key (Accutorr Plus without Trend and SpO2 only). Once enabled, press and hold this key (1 beep tone, approx. 3 seconds) to delete the most recent reading when it is displayed. When displaying any measurement, press and hold this key (2 beep tones, approx. 6 seconds) to delete all information for the currently selected patient. Press and hold at power up to delete all information for all patients. 22. Data Scan Key Press this key (1 beep tone) to view previous measurements for the selected patient on the Accutorr Plus NIBP and to enable the Delete Info. key (Accutorr Plus without Trend and SpO2 only). The LED indicator next to the key illuminates. On the Accutorr Plus NIBP, use the Patient Info. Up & Down Arrow keys (27 & 28) to scroll through the stored measurements for the selected patient. On all models of the Accutorr Plus, press and hold this key (2 beep tones, approx. 6 seconds) to scan all of the rooms and beds for stored measurements. Press the Data Scan key again to stop on a particular room/bed. Press the Data Scan key again to exit this view mode. 23. Data Scan Indicator This LED indicator is illuminated when viewing prior data. 24. Room/Bed Number Key Press this key to change the displayed Room/Bed. After pressing this key use the Patient Info. Up & Down Arrow keys (27 & 28) to change the Room/Bed. This key is also used when selecting a User Configuration item. 25. Bed Letter Display This display is used to show the current patient bed letter. It is also used to display status codes for NIBP, SpO2 and Temperature and to display User Configuration items. 26. Room Number Display This display is used to show the current patient room number. It is also used to display status codes for NIBP, SpO2 and Temperature, indicates which alarm is being set (Hi or Lo), and displays a User Configuration item. 27. Patient Info. Down Arrow Key This key is used to decrement the alarm limits when they are shown on the LED displays and to decrement the hours, minutes, month, day and year in the clock set mode.

Time/Temp Display This displays the time, in minutes since the last successful NIBP measurement (Elap. Time is illuminated). When the Interval key is pressed, the Elap. Time changes to the current Interval setting (Interval is illuminated). When the Predictive thermometer probe is removed from its holder, the Elap. Time changes to Temp (Temp is illuminated). Either “85.0" (° F) or ”29.4" (° C) will display; this is an internal self test feature. As the Predictive thermometer is taking a measurement, the display will flash as the number increases. When the final temperature measurement is determined, the display will no longer flash and a beep tone is generated. When the AccuTemp IR thermometer is used, the temperature is not displayed until after the measurement is taken and the thermometer is placed back into its holder. This display will also show the current time and date when setting the clock. 34. Interval Key Press to enter the set time interval mode. An interval is set for automatic NIBP measurement cycles. To sequence through the interval choices of: OFF (--, when set to display graphics), CONT (Continuous), 1, 2.5, 5, 10, 15, 20, 30, 60, 120 and 240 minutes, repeatedly press the Interval key. When the desired interval is displayed in the Interval/Elap. Time/Temp Display the TIMER/TEMP key may be pressed to enter the interval setting or, the displayed setting will be entered when 15 seconds have elapsed without pressing the Patient Info.
