Selecting Options for the 90341
Lead Display
There are two operational modes available with the 90341 dual-lead transmitter:
(1) the standard mode which offers a choice of one V lead (V1-6), plus lead II, or
(2) the limb lead mode which 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 not a 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. Refer to Patient Preparation and
Electrode Application on page 8-6 for lead placement illustrations.
!
• Both modes work correctly with or without the right leg electrode
attached. However, for optimum performance, the right leg
electrode should always be used.

• If one of the leads fails, a lead fault message will display in the
upper left corner of the waveform zone. If there is not a valid
lead vector, the message LEADS OFF displays and an alarm
tone sounds.
