Battery Installation
The WAM is powered with a single AA battery. When the battery contains sufficient voltage to operate and the
patient is properly connected, an LED on the front of the WAM will appear solid green indicating proper pairing and
communication with the electrocardiograph. A battery with low voltage or a lead fail will result in a flashing green
or yellow LED.
To install a new battery, remove the battery cover by twisting the cover in a counterclockwise direction. Removal of
the battery cover will automatically turn the power off. Insert one AA battery into the battery compartment aligning
the battery’s positive (+) and negative (-) indicators with the designators shown on the device’s back label. Replace
the battery cover by twisting the cover in a clockwise direction. The battery cover will seal the battery compartment
and make contact with the battery providing power to the device.
Applying Power
Before you apply power to the WAM, make sure that patient lead wires do not touch metal connected to ground (this
may happen if reusable electrodes with exposed metal are used); the WAM will auto-calibrate at power-on, and a
large amount of noise caused by ground loops may disrupt calibration, in which case the electrocardiograph will not
display the ECG.
Press the power On/Off button. On initial start up, the LEDs will briefly flash yellow and green and the device will
beep. LED status will indicate the following:
•
Solid green: appropriate battery power level, good electrode-to-skin impedance, and good bidirectional
communication with the electrocardiograph.
•
Flashing green: low battery.
•
Solid yellow: lead fail.
•
Flashing yellow: low battery and/or lead fail.
•
LED off: device not powered on, very low battery (no sound), or device out of range (WAM will beep
intermittently).
Press the power On/Off button to turn the device off. An audible tone will sound indicating power off and RF
disconnect.
Attaching the Lead Wire Connector Block
The 12-lead ECG lead wires consist of one connector block with 10 lead wires (5 leads wires to each side). The lead
wires are positioned on the WAM to follow the contour of the torso. Each lead wire terminates in a medi-clip or 4
mm banana connector.
Securely insert the connector block into the ECG input connector on the top of the WAM.
CAUTION: Be careful to insert the connector block into the appropriate input connector by
matching the lead wire labels to the WAM label.
Labeling the WAM and Electrocardiograph
The WAM ships with self-adhesive letters allowing the user to label the WAM and its paired electrocardiograph. It
is recommended these labels are applied to both the WAM and its paired electrocardiograph to assist in keeping the
units together.
