For 12-lead ECG display screen, refer to 8.11 12-Lead ECG Monitoring (for
uMEC12/uMEC15).
8.5 Changing ECG Settings
8.5.1 Accessing ECG Menus
By selecting the ECG parameter window or waveform area, you can access the [ECG Setup]
menu.
8.5.2 Choosing the Alarm Source
In most cases the HR and PR numerics are identical. In order to avoid simultaneous alarms
on HR and PR, the monitor uses either HR or PR as its active alarm source. To change the
alarm source, select [Alm Source] in the [ECG Setup] menu and then select either:
 [HR]: if you want the HR to be the alarm source for HR/PR.
 [PR]: if you want the PR to be the alarm source for HR/PR.
 [Auto]: If the [Alm Source] is set to [Auto], the patient monitor will use the heart rate
from the ECG measurements as the alarm source whenever a valid heart rate is available.
If the heart rate becomes unavailable, for example the ECG module is turned off or
becomes disconnected, the patient monitor will automatically switch to PR as the alarm
source.
8.5.3 Setting the ECG Lead Set
You can set the [Lead Set] by selecting [ECG Setup][Others>>]. You can set the [Lead
Set] as [Auto] if the auto lead detection function is available.
8.5.4 Choosing an ECG Display Screen
When monitoring with a 5-lead set or 12-lead set, you can select the [Screens] Quickkey. In
the [Choose Screen] window, choose the screen type as:
 [Normal Screen]: The ECG waveform area shows 2 ECG waveforms.
 [ECG 7-Lead Full-Screen]: The whole waveform area shows 7 ECG waveforms only.
 [ECG 7-Lead Half-Screen]: The upper half part of the whole waveform area displays 7
ECG waveforms.
