Recommended Separation Distances for WLAN Operation
To avoid interference in the presence of other RF sources, following separation distances are
recommended;
• A separation distance of 1 m to BlueTooth (Class 1), DECT and WLAN devices (if connected to a
different WLAN infrastructure) operating in the same frequency band.
• A separation distance of 3 m to other radio transmitters with a pulsed mode of operation and a
duty cycle less than 50%, operating in the same frequency band.
• A separation distance of 10 m to a consumer grade microwave oven and 30 m to a commercial
grade microwave oven, if operating in the 2,4 GHz band.
If other continuous wave transmitters operate in the same frequency band, a minimum signal-to-noise
ratio (SNR) of 25 dB should be provided at the monitor location.
These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption
and reflection from structures, objects, and people.
Electrosurgery Interference/Defibrillation/Electrostatic Discharge
The equipment returns to the previous operating mode within 10 seconds without loss of any stored
data. Measurement accuracy may be temporarily decreased while performing electrosurgery or
defibrillation. This does not affect patient or equipment safety. Do not expose the equipment to x-ray
or strong magnetic fields (MRI).
Fast Transients/Bursts
The equipment will return to the previous operating mode within 10 seconds without loss of any
stored data (M1032A within 30 seconds). If any user interaction is required, the monitor indicates this
with a technical alarm (INOP).
Restart time
After a power interruption, an ECG wave will be shown on the display after 30 seconds maximum. If
an X2 is connected to a host monitor, it can take up to a maximum of 45 seconds until the ECG wave
is shown.
