The GSI 18 Audiometer is a single-channel, pure tone, air conduction, portable
instrument designed to provide basic audiometric screening capability for physicians’
offices, schools and industry. The lightweight design allows easy transport to a variety
of testing locations. The clearly labeled front panel controls and full frequency range
make accurate, reliable testing a simple matter for any user.
The GSI 18 is a precisely designed and calibrated instrument. With proper care, it will
deliver accurate sound-pressure levels to subjects’ ears for hearing screening programs.
NOTE: The GSI 18 should be calibrated yearly (or sooner if a problem develops) by a
GSI certified technician. See Chapter 3.
Unpacking and inspection
Although this GSI 18 was carefully tested, inspected and packed for shipping, it is good
practice after receiving the instrument to immediately examine the exterior of the
container for any signs of damage. Notify the carrier if any damage is noted.
Carefully remove the GSI 18 from its shipping container. If the instrument appears to
have suffered mechanical damage, notify the carrier immediately so that a proper claim
can be made. Be certain to save all packing materials so that the claim adjuster can
inspect it as well. As soon as the carrier has completed the inspection, notify a GSI
representative.
If the instrument must be returned to the factory, repack it carefully (in the original
contai
ner if possible) and return it prepaid to the factory for necessary adjustments.
