At A Glance
Introduction
Congratulations on your purchase of the Sentry K300
TM
Encrypted Flash Drive. This user manual
is intended to help you configure your device in conjunction with your company’s SafeConsole
Server. SafeConsole support was introduced to the K300 with firmware version 1.19. See Device
Information to find out which firmware version is currently running on your device. If the device is
currently on 1.08 or lower, please use the links below or contact your system administrator to update
your device. Because DataLocker is constantly updating its products, the images and text in this
manual may vary slightly from the images and text displayed by your Sentry K300. These changes
are minor and should not adversely affect the ease of setup.
Updated software and documentation are freely available for download on our website:
•Updates: latest device updates
•Support: documentation and support
The Sentry K300 stands alone as the only solid state flash drive to incorporate an OLED display to
enable advanced security features. The display supports true alpha-numeric password based
authentication and a full featured on-board menu system.
Although the Sentry K300 is extremely user friendly, it is recommended that you review this guide to
ensure that you become fully acquainted with the Sentry K300 and all of its features.
About the Sentry K300
The DataLocker Sentry K300 offers affordable military-grade security with 256-bit AES hardware-
based encryption in XTS mode that provides always on protection for your data. Unlike software-
based encryption, the Sentry K300 cryptochip does not export encryption keys to the host PC,
thereby protecting against cold-boot and malware attacks.
What Systems Can I Use It On?
• Windows® 10
• Windows® 8.1
• Windows® 7
• Any computer that supports USB mass storage when used in Standalone* mode.
*Standalone mode is disabled by default and controlled by your SafeConsole Administrator.

device.
• You can also use the keyboard shortcut: CTRL + L (Windows only), or right-click the
DataLocker Icon in the system tray and click Lock Device.
Note: Managed devices will automatically lock during use if an administrator remotely disables
the device. You will not be able to unlock the device until the System Administrator re-enables the
device.
To set a device to automatically lock:
1. Unlock your device and click Settings on the menu bar in the DataLocker Control Panel.
2. Click Preferences in the left sidebar.

Features
Standalone Logins
Requesting Standalone Logins
Standalone mode allows the Secure Volume of the Sentry K300 to be accessed by any computer
that has support for removable storage. Standalone mode is controlled by a policy that is set by
your SafeConsole Administrator. If this mode is not available, please contact them to enable this
feature. SafeConsole administrators will define the maximum allowed times the Sentry K300 can be
unlocked in Standalone mode before the device needs to be returned to a Windows computer to
check in.
To request Standalone logins, perform the following steps on a workstation that has a valid connec-
tion to the SafeConsole server:
1. Connect the Sentry K300 in SafeConsole mode. See the SafeConsole Mode for more informa-
tion.
2. On the K300 Control Panel, click the Gear Icon to open up settings.
3. Select the Standalone tab.

2. Once the password is confirmed, the Sentry K300 will change the password back to the default
of ‘1234567’ and prompt to change the password.
3. The password should be changed to something secure. Continuing to use the Sentry K300
without changing the password will result in the device forcing a password change. For more
information see Changing Device Password
Important: A password recovery code can only be used once. The Sentry K300 must be unlocked
in SafeConsole Mode with a valid connection to SafeConsole before a new password recovery
code can be generated. Failure to do so could cause lose of access to the device and the data
on it if the password is forgotten again.
Unlocking In Read-Only Mode
You can unlock your device in a read-only state so that files cannot be altered on your secure drive.
For example, when using an untrusted or unknown computer, unlocking your device in Read-Only
Mode will prevent any malware on that computer from infecting your device or modifying your files.
Managed devices can be forced to unlock in a read-only state by an administrator.
When working in this mode, the DataLocker Control Panel will display the text Read-Only Mode.
In this mode, you cannot perform any operations that involve modifying files on the device. For
example, you cannot reformat the device, restore applications or edit the Applications List, or edit
files on the drive.
To unlock the device in Read-Only Mode through the Control Panel:
