Sentry K300 User Guide

At A Glance

Introduction

Congratulations on your purchase of the Sentry K300

Encrypted Flash Drive. This user manual

is intended to help you conﬁgure 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 affect the ease of setup adversely.

Updated software and documentation are freely available for download at our website:

•Updates: latest device updates

•Support: documentation and support

The Sentry K300 stands alone as the only platform independent, keypad, 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. With

modern security policies requiring alpha-numeric passwords, the Sentry K300 is the only storage

device with full support for alpha and numeric characters.

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.

The Sentry K300 is completely cross-platform compatible and OS agnostic. With no software or

special drivers required, the Sentry K300 works with Windows, Linux, macOS, Android phones and

tablets, Chromebooks, and embedded systems - any system that can utilize USB Mass Storage.

Since the Sentry K300 also has its own power supply, the device can be used as a bootable device

running Windows to Go, Ubuntu Linux, the local operating system, or other portable operating

systems.

Best Practices

•

If the battery within the device is low or dead, charge it by plugging it into a certiﬁed USB port

for 30 minutes before using the drive.

• Remove the device from the computer before using the keypad to prevent USB damage.

• The device must be completely dry before connecting to a computer.

• Only connect the device to certiﬁed USB ports.

•

Safely eject the device from the operating system before removing it. For more information,

see Accessing The Sentry K300.

• Use a strong password and be sure to remember it.

•

Use the correct ﬁle system based on operating system and ﬁle needs. See Formatting The

Sentry K300 for more information.

This section will guide you through the necessary steps to set up the Sentry K300 drive. It is highly

recommended that you set an administrator password using alpha-numeric characters.

The default password for the device is set to 1234567. This password allows access to the device

3 times before forcing the user to change it. Once the 3 entries with the default password have

been used, the message “You must change default password” will scroll across the screen until the

password is changed. Press any button to continue to the Change Password screen.

Note:

Zeroizing the drive by using the menu option or initiating Self Destruct with too many password

attempts will set the password back to the default upon reinitialization.
