This symbol indicates the location of a service adjustment part and is
intended for service personnel only. The GSI 18 is a specifically calibrated
audiometer and the periodic service and adjustments for the instrument that
may be required should be done only by an authorized GSI service technician.
Please read the entire manual prior to using the GSI 18 to become familiar with
the test functions and proper accessory connections.
Accessory equipment connected to the analog and digital interfaces must be
certified to the respective IEC standards (IEC950 for data processing or IEC
60601-1 for medical equipment). Furthermore, all configurations shall comply
with the system standard IEC 60601-1-1. Anyone who connects additional
equipment to the signal input or signal output port configures a medical system,
and is therefore responsible that the system complies with the requirements of
the system standard IEC60601-1-1. If in doubt, consult the technical service
department or local GSI representative.
