Safety and Performance Tests
Recommended separation distances from portable and mobile RF
communication equipment
The monitor is intended for use in an electromagnetic environment in which radiated RF disturbances
are controlled. The customer or user of the monitor can help prevent electromagnetic interference by
maintaining a minimum distance between portable and mobile RF communications equipment and
the monitor as recommended below, according to the maximum output power of the communications
equipment.
In the following table, P is the maximum output power rating of the transmitter in watts (W)
according to the transmitter manufacturer and d is the recommended separation distance in metres
(m). The values given in brackets are for those measurements which do not use the general formula.

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 electro-surgery 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. If any user interaction is required, the monitor indicates with a technical alarm (INOP).
Restart time
After power interruption, an ECG wave will be shown on the display after 30 seconds maximum.
