2.3 Mains supply operation
The audiometer is designed for continuous operation and is
powered by a mains adapter which is supplied, and specified
as part of the equipment. If a replacement is required, please
contact your local Service department (see Annexx 5).
All other connections must be made before connecting the output
lead from the adapter into the POWER input socket on the back of
the audiometer. Switch on the mains supply - the indicator on the
adapter and the POWER indicator on the audiometer will both
illuminate green, showing that the instrument is ready for use.
The output from mains adapter is fitted with electronic circuit
protection. In case of overload the adapter will shut down and the
indicator will be extinguished. When the fault is cleared the adapter
will operate as normal.
The input is to the mains adapter is protected with a non-replacea-
ble fuse. If this fails the adapter will not operate.
The mains adapter is the mains disconnect device and therefore
the audiometer should be positioned such that easy access to the
mains adapter is possible.

STRUMENT.
To comply with the standards IEC 60601-1 for safety and
IEC 60601-1-2 for EMC the audiometer is designed to be used

the product. If a replacement is required, please contact your
local Service department (see Annexx 5).
