Preventive maintenance
To maximize the service life of the audiometer and headset, the following is
recommended:
1. Turn the instrument off when not in use.
2. Dust the instrument occasionally with a soft, dry cloth.
3. Wipe the headset cords and ear cushions occasionally with a warm damp cloth.
4. Leave the earphones connected to the audiometer permanently to minimize
straining the connections. Should it be necessary to remove the headset, always
grasp the barrel of the connecting plugs and pull straight out – never pull on
the cords.
5. Avoid dropping the earphones or snapping them together as this could affect
the calibration accuracy.
Cleaning the GSI 18
Preventive maintenance includes periodically cleaning and inspecting the exterior
of the instrument. It is recommended that you develop a s chedule for these
purposes. Unless otherwise noted, the frequency of instrument cleaning can be
determined by the user, depending on the conditions and frequency of use. It is
recommended that the instrument is cleaned at least annually.
Turn OFF the system and disconnect the power before cleaning the instrument. Use
a soft cloth lightly dampened with cleaning solution to clean all exposed surfaces.
Take care to not allow liquid to come in contact with the metal parts inside the
transducers (e.g., earphones / headphones). Do not permit solutions or disinfecting
agents to seep into the electronic portions of the system. Take special care around
controls, connectors and panel edges. Remove any dust from the exterior of the
system with a soft brush or cloth. Use a brush to dislodge any dirt on or around the
connectors and panel edges. Remove stubborn dirt with a soft cloth slightly
dampened with mild detergent and water. Wipe surfaces dry afterward. Do not use
the instrument or transducers until they are completely dry.
