Two Operational Modes
Two operational modes are available with the 91341 dual-lead transmitter:
• the standard mode that offers a choice of one V lead (V1-6), plus lead II; or
• the limb lead mode that offers choices of the leads I, II, III, AVR, AVL, or AVF.
The standard mode is available if the chest lead is applied. The limb lead mode is
available when there is no chest lead applied. Loss of the chest electrode
changes the ECG - Lead Select menu to the limb lead mode if the left arm, left leg,
and right arm electrodes are intact.

• With dual-lead transmitters, both modes work correctly with or
without the right leg electrode attached. However, for optimum
performance, the right leg electrode should always be used.

• With dual-lead transmitters, if one of the leads fails, a lead fault
message will be displayed in the upper left corner of the
waveform zone. If there is no valid lead vector, the message
LEADS OFF is displayed and an alarm tone is generated.
