NOTE 1 At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE 2 These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption
and reflection from structures, objects and people.
a
Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land
mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically
with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic
site survey should be considered. If the measured field strength in the location in which the Asra is used
exceeds the applicable RF compliance level above, the Asra should be observed to verify normal operation. If
abnormal performance is observed, additional measures may be necessary, such as re-orientating or relocating
the Asra
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.

•
The ASRA Curve Audiometer is powered by an external universal mains power module.

mains plug.
•
It complies with the specification for Class 1 ME equipment, and can be used along
with a PC and printer, normally supplied by the customer. NB the warning made earlier
about the PC and printer being compliant with EN 60950 and placing these items out
of the reach of a subject.
•
The Applied Parts comprise, Right and Left Headset and the Response Button, which
are classified as type B applied part.
•
The enclosure does not provide protection against the ingress of liquids and is
therefore classified as IPX0. The supplied PSU enclosure does not provide protection
against the ingress of liquids but does have level 2 degree of protection and is rating
IP20.
•
There are no parts which are supplied sterile or are required to be sterile.
•
The ASRA Curve Audiometer is
NOT
suitable for use in an oxygen rich environment.
•
The ASRA Curve Audiometer is rated for continuous use.
•
The ASRA Curve serial number can be found on the label on the back panel, and the
software version number can be viewed on the start-up screen and by clicking on Help,
