About the System Software Introduction
Your SonoSite system contains software that controls its operation. From time to time, SonoSite may provide new software for use with your system. This software is provided using a software update module or a transducer. This software is either required or optional. A single module or transducer can be used to update one or more systems. When the new software is required, you must install it if you wish to use the new software features (e.g., new transducer). If you choose not to install it, you must remove the transducer and replace it with one that is compatible with the software that is currently installed in your system. When the software is optional, you can either install it or choose to use your existing software. If you choose not to install the software, the system will prompt you again whenever the system is started, and whenever the transducer is disconnected and then reconnected to the system. See “Upgrading the System Software” on page 10 for more information on software upgrades.
Software Licensing Use of the software that you receive from SonoSite is controlled by a license key. A license key is a number sequence containing exactly 12 decimal digits. License keys are obtained from SonoSite or from its authorized representatives. You must obtain one key for each system that will use the new software. See “Obtaining a License Key” on page 11 for information on obtaining a license key. Software that you receive from SonoSite may be installed and will operate for a short period of time without requiring a valid license key. We refer to this period of time as the “grace period.” The grace period is variable. When you first install your software, your SonoSite system will prompt you for a license key. If you have not yet obtained a valid license key, you can elect to use the software as long as the grace period time has not been fully consumed. We refer to this mode of operation as “running in the grace period.” When a system is running in the grace period, all system functions are available. As you use the system, the grace period is slowly consumed. When the grace period has expired, the system will not be usable until a valid license key has been entered. Grace period time is not consumed while the system is powered off or when it is in “sleep” mode. Whenever a system is running in the grace period, the grace period time remaining is available on the license update screen. For information on displaying this screen, see “Installing a License Key” on page 12“. Caution:
When the grace period expires, all system functions except for licensing will become unavailable until a valid license key is entered into the system.

Upgrading the System Software As described in Chapter 1, “Introduction”, on page 1, transducers that you receive from SonoSite may contain either required or optional upgrades to the system software that resides on your SonoSite system. Whenever you connect a transducer to a SonoSite system, the system communicates with the transducer to determine if it contains software that would upgrade the system. Caution:
Initiating any upgrade of the system software erases any images stored on your system. Do not upgrade the system software until you have determined that any stored images are no longer needed.
To upgrade the system software: 1
When you first connect a transducer with new software and turn the system on, the following message is displayed: Do you want to upgrade the system software?
