8 Bedrock SMxx operating manual © Bedrock Audio BV, 2019
3. How to use this manual
Depending on how you plan to use your Bedrock SMxx, not all information in this manual
may be equally interesting or relevant. If you are new to the Bedrock SMxx, we strongly
recommend that you read the following chapters:
• Chapter 4: General use and safety precautions
• Chapter 5: Getting started
• Chapters on the measurement modules that you plan to use first
• Chapter 13: Power and charging
• Chapter 14: Cleaning, maintenance and calibration
We recommend reading the chapters on the various measurement modules as you plan to
use them. As some of the modules implement complex measurement procedures, using
those modules may require you to spend some time with this manual, and possibly also
third-party source of information (such as online tutorials and course manuals).
The following sections should be read if you are experiencing issues with your device or if
you need to upgrade your firmware:
• Before getting support from your Bedrock audio vendor, please consult the
Troubleshooting section (chapter 19)
• Consult the section on Firmware updates (chapter 16) before trying to in-
stall new firmware on your device. Failure to follow firmware update in-
structions precisely may render your device permanently inoperable and
voids your warranty.
Towards the end of this manual, you will find detailed information in tables and appendi-
ces that may not be needed for everyday use of the device. In particular, these appendices
contain procedures for periodic testing, as needed by 3rd party labs for calibration and (re-)
certification of your instrument.
New in firmware version 2.4
If you have previously used the Bedrock SMxx but have recently upgrade to firmware 2.x.x
we recommend that you read the “Getting started” section to get acquainted with the new
structure of the Home menu (which is now user-configurable). New modules introduced
in FW2.x.x are: Speech Level Meter, Full STI, AC Volt meter, Noise Curves and RTA log-
ging. Functionality of RT60 has been enhanced, and a remote control API for 3rd party
apps is now available. Full STI and Speech Level Meter are not available to SM30 users.
