The storage and operating environment for a 1902 must not
exceed the temperature range 0° to +50° Celsius, in conditions
of non-condensing humidity which should not exceed 95%
saturation, in an atmospheric pressure range of 500 hPa to
1060 hPa. The 1902 complies with relevant EU and USA
requirements for electromagnetic interference. The 1902 is
suitable for continuous operation. The 1902 is not protected
against ingress of water or dust. There are no hazardous
voltages inside the 1902. The 1902 can be recycled; please
contact CED for further details.
The 1902 offers Class I protection against electric shock. To
maintain the safety standard, accessory equipment attached to
the 1902 must also comply with relevant safety requirements
such as IEC601-1 or the relevant IEC standard e.g. EN60601-1
configured to comply with EN60601-1-1:2000.
The ‘Common’ lead on a three-wire electrode cable provides a
return path for the input amplifier bias currents. UNDER NO
CIRCUMSTANCES should this lead or any other electrode
lead be connected to mains earth. This will negate the 1902’s
isolation provisions and expose subjects to the risk of fatal
shock.
The 1902 is not protected against flammable anaesthetic
mixtures. It must NOT be used in the presence of such
mixtures.
