Introduction

Thank you for purchasing a Siemens audiometer. The Siemens
SD 270 is a diagnostic audiometer that will give many years of
reliable service if treated with care.

1.1 Intended applications

The Siemens SD 270 diagnostic audiometer is designed for use by
audiologists, general practitioners, hearing aid dispensers and child
health professionals. Capable of undertaking both air and bone
conduction tests with or without masking, the audiometer also has
many additional features such as the facility to support speech au-
diometry from live or recorded sources, the option to select
free-field equivalent output from the headphones in speech mode
and a range of clinical audiometry tests.

1.2 Unpacking

Open the shipping carton and carefully remove all the equipment.
Check against the delivery note that all the accessories ordered
have been included with your audiometer. If anything is missing,
please contact your local Service department – see Appendix 5.
If you have purchased from a distributor you should contact them
directly.
Please retain the shipping carton and packing materials as the
audiometer will need calibrating on an annual basis and should
be returned for service in its original shipping carton.
