USER SAFETY INFORMATION
11
If the WAM battery cover is opened during transmission, the device will stop transmitting. The battery must be
reinserted and the cover must be applied to resume operation.
The WAM will automatically turn off (LEDs off) if the battery has been severely discharged.
The WAM will automatically turn off when the electrocardiograph is powered down.
The display of absent waveform while using the WAM wireless acquisition module could be due to the WAM
being turned off or having no battery, or the WAM being out of range or experiencing a calibration error.
Review the LED indicator on the WAM to ensure the unit is turned on and has proper battery level. Ensure the
WAM is paired correctly and is within recommended proximity of the electrocardiograph, and/or power cycle
the WAM to re-calibrate.
The display of absent waveform display while using the AM12 or AM15E acquisition module could be due to
an improper auto-calibration. Reconnect the AM12/AM15E or power cycle the electrocardiograph.
Square waves on the display and rhythm printout could be due to the WAM or the AM12/AM15E lead wires
not being connected to the patient.
As defined by IEC 60601-1 and IEC 60601-2-25, the device is classified as follows:
Class I equipment or internally powered.
Type CF defibrillation-proof applied parts.
Ordinary equipment.
Equipment not suitable for use in the presence of a flammable anesthetic mixture.
Continuous operation.
NOTE: From a safety perspective, per IEC 60601-1 and derivative standards/norms, this device is
declared to be “Class I” and uses a three-prong inlet to ensure an earth connection is made along with
mains. The ground terminal on the mains inlet is the only protective earth point in the device. Exposed
metal accessible during normal operation is double insulated from mains. Internal connections to earth
ground are functional earth.
This device is intended to be used in a hospital or doctor’s office setting, and should be used and stored
according to the environmental conditions specified below:
Operating temperature:
+10° to +40°C (+50° to +104°F)
Operating humidity:
10% to 95% RH, non-condensing
Storage temperature:
-40° to +70°C (-40° to +158°F)
Storage humidity:
10% to 95% RH, non-condensing
Atmospheric pressure:
500 hPa to 1060 hPa
The device will automatically turn off (blank screen) if the batteries have been severely discharged and the AC
mains is disconnected from the device.
After operating the device using battery power, always reconnect the power cord. This ensures that the batteries
will be automatically recharged for the next time you use the device. A light next to the on/off switch will
illuminate indicating that the device is charging.
