The GPS ready underwater tablet
User Manual

AQUATAB S is a compact underwater tablet with a fully functional touch screen for entering
information with a special stylus AQUATAB PEN, which allows divers to take notes
underwater, collect and process data, save information, take photos, record videos, access
information and run any Android application underwater.
AQUATAB S includes pre-installed smartphones of models: Samsung Galaxy Note 10 lite,
Samsung Galaxy Note 20 Ultra or Samsung Galaxy S21 Ultra. Before placing an order, the
buyer has the flexibility to choose one of the supported smartphones. This allows the buyer
to match the requirements for performance, memory, display resolution and camera. The
chosen smartphone is then modified and incorporated into AQUATAB S. The standard
Commercial off-the-shelf (COTS) version has Samsung Galaxy Note 10 lite smartphone,
which contains the most optimal features for general tasks and allows running standard set
of Android applications.
AQUATAB S has a specially designed pre-installed module that receives navigational data
from a GPS receiver, which allows divers to use navigation, localize the diver’s own geo-
position, mark the underwater targets/locations with GPS coordinates on the inbuilt
mapping app with pre-loaded offline maps. The underwater navigation operates in
conjunction with RedWave
1
system, which includes a set (minimum 4) of lightweight surface
buoys, technically satellite navigation signal repeaters, which implements a long navigation
base and RedNAV hydroacoustic modem-receiver connected to AQUATAB S through a sealed
connector.
Optionally, AQUATAB S can be connected to the surface-based system AQUATAB FLOATING
BASE in order to exchange the navigation data as well as provide a wired Internet connection,
which technically makes it possible to determine a diver’s location in an unlimited water area
and support data exchange through media content or information using the Internet. In
contrary with RedWave solution, AQUATAB floating base relies on one single GPS signal
source, where the accuracy of localization may be reduced, while RedWave provides more
accurate position through implementation of adaptive intelligent trilateral localization
algorithms.
 RedWave and AQUATAB FLOATING BASE are separate solutions and are sold separately.
Please read this User Manual carefully before using the device underwater. Devices and
software are constantly evolving –the information and illustrations contained in this manual
is subject to change and should be used for reference only as they may be changed without
notice.

The RedWave navigation system, as well as its components: the RedBase repeater buoys and the RedNODE acoustic
receiver are developed by Underwater Communications and Navigation Laboratory LLC. More information about

To ensure the safe and correct use of the AQUATAB S underwater tablet, it is important that
you also read the instructions and documentation for the respective smartphone, available
on the website of the smartphone manufacturer www.samsung.com. Information about
standard functions are available in these instructions and documentation and we
recommend you to be acquainted with them in details. Please note that the smartphone
manufacturer is not responsible for the use of the smartphone in the AQUATAB S. In case of
any technical problems with the AQUATAB S, please refer to Sections 11-13.

2Precautions.
AQUATAB S has been designed and tested for use at depths of up to 100 meters / 328 feet.
Carefully inspect the device before diving, if you find cracks on the protective glass or rear
chamber or fogging inside the case, please DO NOT use the device, and DO NOT connect it
to the mains. These signs indicate a housing seal failure, needs inspection, and possibly
require repairing by a specialist.
 WARNING! Do not try to disassemble the device yourself, it is strictly prohibited!
Before diving, check that the protective cap of the sealed connector is in place and tightly
closed. It should be tightened with a little effort without using excessive force or special tools.
Do not dive without the protective cap as this may damage the device.
Turn on the device according to Section 3 and check the charge level:
-the main battery (please refer to Section 5),
-an additional battery (please refer to Section 5).
Make sure your device is fully charged. To fully enjoy the functionality of AQUATAB S during
the whole dive, we highly recommend not to use the device if the battery charge is below
60%.
Do not drop the device and avoid prolonged vibrations or exposure to heat sources or direct
sunlight.
The MAXIMUM OPERATING DEPTH for the AQUATAB S is 100 meters / 328 feet in seawater.
 WARNING! The use of any software or application on the AQUATAB S is not a substitute for
proper diving equipment and instruments or backup equipment. Make sure you are using the
correct equipment, including a depth gauge, compass, pressure gauge, timer or watch, and have
access to decompression tables every time you dive with the AQUATAB S.

3Getting started. Quick start.
 Attention! AQUATAB S has no buttons, which guarantees increased reliability and water
resistance.
In order to turn on/off the AQUATAB S, you need to bring the magnet/magnetic element
(included) to a special area on the front or back of the AQUATAB S and hold for 8 seconds
until vibration:
Upon start and OS load, you will see the Home screen.
Apps:
-Compass App
-Maps App - OsmAnd
-AQUATAB App
-Settings
-Camera
-Gallery
-Apps Screen
-Widget with Date, time and weather.
 Important! The desktop can be customized by the user
according to his/her needs. However, deletion of key
applications 1 (Compass), 2 (OsmAnd), 3 (AQUATAB) might
make it impossible to re-install them yourself or their
installation version might not match the version of the
operating system.

 Important! For unrestricted and east use, the manufacturer has configured all pre-installed
software and set optimal settings of AQUATAB S. In order to preserve the functionality, we
highly recommend avoiding changing system settings, performing operating system update
and/or uninstalling pre-installed applications without contacting technical support of the
manufacturer. In case these requirements are violated, the manufacturer may not guarantee
the correct operation of AQUATAB S.
AQUATAB S is operated using a special stylus, which allows divers to work with gloves and,
at the same time, enter data, click small icons on the desktop, draw any diagrams or take
notes, etc.
More information about using Stylus is located in Section 4.
Using the icons at the bottom of the home
screen, you can perform a number of basic
functions:
1. Return - return to the previous screen,
cancel an action, etc.
2. Home - return to the main screen.
3. Windows –view active applications with
the ability to close them.

4Using Stylus AQUATAB Pen
AQUATAB S is operated using a special stylus, which allows divers to work with gloves and,
at the same time, enter data, click small icons on the desktop, draw any diagrams or take
notes, etc.
Despite the fact that the stylus is electronic, it does not
require charging. The stylus collects required charge
while interacting with the screen of the AQUATAB S using
the electromagnetic induction.
1. Pen tip (replaceable).
2. Stylus button.
3. Eyelet for fastening to AQUATAB S case.
To use the stylus, lightly touch AQUATAB S protective glass using the pen tip. There is no
need to apply excessive force, as the stylus is quite sensitive to pressure. With the help of
the stylus, you can launch and manage applications, as well as make various drawings,
diagrams and handwriting with the ability to recognize text.
Use the AQUATAB PEN like a pen - place it comfortably in your hand.
 Important! Please note that some parts of the screen might be less sensitive and hence
you may experience slower reaction to stylus actions. In such cases, please keep in mind that
using the stylus closer to 45° ensures optimal interaction between the stylus and the screen.
The stylus incorporates a button designed to activate additional functions. Pressing the
button once or twice activates various commands. For example, bringing the stylus tip close
to the screen (without touching it) and pressing the button twice activates the additional
functions menu. This shortcut menu for additional functions is customizable.
When using the applications for drawing, pressing the button will activate the eraser
function.
For more information about the various functions of the stylus, please visit the website of
the manufacturer of the smartphone installed in your AQUATAB S.
