Operation (5-Lead, 5L, LT and XG) Controls, Indicators and Connectors (5-Lead, 5L, LT)
3. END (Set-Up)
A single action key which causes the display to return to the main screen display (as
specified in the DISPLAY section). This key is always available.
4. CENTRAL SILENCE (Optional)
A single-action key which mutes the alarms of the corresponding channel on the VISA Central
Station. The amount of time the alarms are silenced, is determined by the VISA.
5. LEAD (ECG)
A single action key which selects the ECG lead to be displayed. Each depression of the key
selects and displays the next ECG lead from the list. The list wraps around after the last entry
is selected. Choices are: I, II, III, aVR, aVL, aVF or V.
6. SIZE (ECG)
A single action key which selects the ECG size to be displayed. Each depression of the key
selects and displays the next ECG size from the list. The list wraps around after the last entry
is selected.
7. FREEZE (Screen)
A single action key which enables or releases the screen freeze function. The freeze key
stops or starts the ECG waveform (waveform 1), except when waveform 2 is used for
cascaded ECG. When this is the case, pressing the freeze key the first time causes the
currently displayed ECG waveform data to be transferred to waveform 2 and frozen.
Waveforms 1 and 3 continue to move. Pressing FREEZE again causes waveform 2 to return
to cascaded ECG.
8. ZERO 1 (IBP) (Optional)
A delayed action key which zeros the current pressure in the BP1 channel. If the transducer
zero process is unsuccessful, “UNABLE TO ZERO” is displayed in the window containing BP
value. This key is only available when a pressure transducer is present.
9. ZERO 2 (IBP) (Optional)
A delayed action key which zeros the current pressure in the BP2 channel. If the transducer
zero process is unsuccessful, “UNABLE TO ZERO” is displayed in a temporary window
within the parameter window. This key is only available when a pressure transducer is
present.
10. START (NIBP)
A single action key which initiates an NIBP measurement. This function is not available if a
measurement is in progress.
11. INTERVAL (NIBP)
A repeat action key which selects the interval setting for NIBP measurements. Values wrap
around at the lowest/highest choices. Choices are: Off, Continuous, 1, 2.5, 5, 10, 15, 20,
30, 60, and 120 minutes. Five seconds after the selection is made and the key is released,
the new interval takes effect.
