options of [Pacer Reject] are invalid.

In the [ECG Setup] menu:
You can select [ECG], [ECG1], or [ECG2] to select a lead to view. The waveform of
selected lead should have the following characteristics:
The QRS should be either completely above or below the baseline and it should not
be biphasic.
The QRS should be tall and narrow.
The P-waves and T-waves should be less than 0.2mV.
If the wave is too small or clipped, you can change its size by selecting an appropriate
[Gain] setting. If you select [Auto] from [Gain], the patient monitor will automatically
adjust the size of the ECG waves. In normal screen, only the selected ECG wave’s size
is adjusted. In other screens, all ECG waves’ size is adjusted simultaneously.
