LED Display Battery Voltage Indicator
The WAM is powered with a single AA battery.
When the battery contains sufficient voltage and the patient is connected, the LED’s on the front of the WAM will
display a solid Green LED representing the current battery voltage is sufficient to operate and communicate with
ELI 350. If a battery with low voltage is inserted and the LED does not illuminate, or a Yellow LED is present a
new battery must be installed. Please review table on following page to assure indicator messages are understood.
Using the Buttons
Three buttons located on the front of the WAM are available for powering the WAM On/Off, acquire a 12 lead
ECG, and for acquire a rhythm strip:

Start Up
On initial start up, the green and yellow LEDs on the WAM will briefly turn and and the unit will beep. The WAM
indicates the following information through the LED:
o Solid Green: appropriate battery power level, good electrode-to-skin impedance, and good
bidirectional communication with the electrocardiograph.
o Flashing Green: Low battery
o Solid Yellow: Lead Fail
o Flashing Yellow: Low battery and lead fail
o LED Off: unit not powered on, very low battery (no sound), or device out of range (WAM
will beep intermittently).
Note: See LED Indicators page for further information
Lead Check
LEAD CHECK is a valuable tool for verifying and optimizing signal quality. This is done automatically through
visual communication with two LEDs located on the front of the WAM. These two LEDs are green and yellow in
color and may be seen as a solid color, flashing on and off, or alternating between green and yellow.
Note: A solid Green LED represents the impedance measured at the right arm (RA), left arm (LA), left
leg (LL), and V1 through V6 electrodes is adequate for ECG acquisition. A yellow LED indicates a
lead fail condition is present. See the cardiograph for more information.
