Mains operation
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
