TABLE OF CONTENTS
What is Project JTab?
As in our other projects (Al Levavcha, Boox Buki and JTab), We looked
for a way to allow a Ben Torah to enjoy technology while not being
exposed to harm from it. Our goal was to design a product that is: 100%
kosher, 100% safe, 100% branded, and 100% Windows 8.1.
There are many computers and tablets, and then there is the JTab. The
JTab is a computer that sports an ocial Windows operating system,
and is unique in that there is no way to bypass it’s restrictions, no way
to watch movies or go online. It is even safe for a young boy to study
with it, without the fear of having someone help him change the the
device settings.
If you connect the JTab to a wide screen - wirelessly or otherwise - and
connect it to a keyboard and mouse, you can use it as a fully functional
personal computer. JTab includes dozens of high-quality applications,
installed and configured for optimal usage. JTab allows you to use the
ת”וש, the observant disc (DBS), Otzar Hahochma, and enables you to
edit books using full Oce and graphics applications.
This device was locked in the safest possible way, and it is virtually
impossible to add applications to those already on the device. Any
attempt to crack the device, if discovered by us will possibly damage the
device and will certainly remove any liability we have for maintaining
and repairing the device.
We hope and pray that we will be able to continue to oer solutions in the
confines of our holy religion that will allow believers to use technology.
Our aim is to protect our community against the many dangers that it
faces and those aiming to harm the purity of our community. We would
be more than happy to receive any suggestions and ideas regarding

- 6 -
proper and safe ways to use technology.
WARNING AND DISCLAIMER
Using this device incorrectly may cause a dramatic loss of data and
many hours of work. Therefore, it is necessary to use this device
carefully, back up your work often, and never do what you don’t know
how to do. This manual was written for the benefit of users of JTab.
JTab has many high quality applications installed, which ensure a fast
and eective experience for a Ben Torah. Here are the major types of
applications installed on the device:
A. Religious applications for studying Torah and writing Hidushei
Torah. JTab is capable of presenting all types of text and digital book
files. It includes the possibility to activate, religious disc (DBS), Otzar
Hahochma, Al Levavecha, Orieta, Torat Emet, applications that present
times of Halacha worldwide, a Hebrew calendar with a page of the day,
and more.
B. Applications that are used to edit Word, Excel and Access files, and
applications for compiling notes and lists.
C. Various helpful applications such as a sophisticated alarm clock,
income and expenses, and a personal database.
D. Music applications with recording capabilities, editing and cutting
MP3 files.
