2.1 Power Supply Selection Guide update for monitors
IMPORTANT: To ensure stability, a dedicated adapter of 5V @ 2.5 A power supply is required to power
the eZeePC. Any power supply with current capacity less than 2.5 A may damage the file system and/or
hardware. Do not plug this device to a multi-point plug that is shared with other devices.
We strongly recommend the usage of a UPS min 600 VA to be connected to the product as it is loaded
with appropriate software and drivers and to prevent data corruption which may lead to data loss.
2.2 Ready to Go
Please proceed in order of steps given below:
1. Unbox and place the eZeePC with the logo facing upwards, on the worktable and make sure that
it is adequately ventilated to enable proper air circulation.
2. Connect your eZeePC Desktop to an HDMI TV by connecting the HDMI cable between HDMI-1 (as
indicated in Fig 2.1) to HDMI input of your TV or HDMI Display Monitor.
3. Connect the power cord with the Charger and C Port Power cable provided, to power socket as
shown in Fig 2.1.
4. Check that Nano Receivers are firmly in place in black slot USB 2.0 slot. There are 2 Nano
Receivers one for the Keyboard and Mouse and the second for the Microphone.
5. Blue Slots USB 3.0 is for external HDD & other peripherals like Printer which you may connect
when needed.
6. Turn on the Power Switch of the Key Board and Mouse, found at the bottom. A Red light should
glow, else check if batteries need to be fitted or replaced.
7. You are now set and Turn on the Power to the eZeePC.
8. Use the TV Remote and change the Display Source to HDMI -1 2 or 3 to whichever the HDMI
cable has been connected to in the TV side.
9. System will boot within 60 seconds and ready for use. You should see a desktop with 4 symbols
on the Task Bar –Raspberry, Internet, and File Manager & Terminal on the left hand side.
Bluetooth, Wi-Fi, Audio Speaker and Clock are on the right hand side. The Desktop has the Quick
Start Guide preloaded.(see picture below)
10. You need to enable the WIFI by clicking the WIFI Symbol on the Bottom side of the Screen .You
will be prompted to key in your WIFI Password to connect to the WIFI.
11. You could also connect to the LAN terminal by connecting a LAN cable to your Switch and
configure accordingly.
2.3 Key Software and Updates provided.
Raspberry Pi OS (previously called Raspbian) is the recommended operating system for normal use. Your
PiTronix eZeePC is already loaded, fully tested and is ready to use.

3 QUICK NAVIGATION and TASK BAR
The Taskbar (Top Left OR Bottom Left) has 4 symbols –namely a Raspberry, Internet, File Manager and
Terminal.
1. Raspberry is the main menu and has multiple applications, including Accessories, Games,
Programming, LibreOffice (for word processing, calculations, and presentations), Preferences, Games,
Logout. See figure below.
The Preferences Menu has the option to Add/Remove Programs, Appearance Settings,
Keyboard & Mouse settings, Screen Resolution etc.
Click “Preferences - Screen Configuration - HDMI1 - Configure - Screen - Resolution”. A list of
possible resolutions appears. Click one that you need and then “Ok”. Save by clicking on the
Yellow mark.
To confirm this change, you will need to click the “OK” button within 10 seconds. Preferred
setting for Resolution would be to keep it to Default.
The Programming Menu gives options of Java,Thonny Python and other programming
languages.
The Office Menu gives LibreWrite –wordprocessor, LibreCalc –spreadsheet, LibreIMpress –
presentations, Libre Base –database. These are similar to other tools used in popular operating

systems like Windows.
Similarly the other menu items provide applications and utilities for the user. Explore and now
your eZeePC.
The Accessories Menu has File Manager, PDF Viewer, Calculator etc. See Figure below
2. Internet- opens DuckDuckGo as default browser. You can surf the Internet and access any
information
3. File Manager- as the name suggests shows all folders and files on your computer. You can drag and
drop files and folders, rename them, copy or paste
4. Terminal -You are advised to use the Terminal only if you are an experienced Linux user.
3.1 Real Time Clock (RTC)
Each time your eZeePC starts up it will connect to what is called a Network Time Protocol (NTP) server
and request the time.
If there is no internet connection the eZeePC utilizes the integrated RTC on the Pi Desktop add-on board.
This contains a battery powered clock chip that tells what time it is. To ensure accuracy the time will
need to be set on the system initially.
Note: Installing the software package then rebooting the system will enable the RTC.

3.2 Web Cam Interface
eZeePC comes with a Webcam which interfaces with the USB port.
Connect the Camera USB cable to the USB 3.0 Port of the eZeePC.
Adjust the Back Light provided to the required Lighting levels by rotating the knob if applicable
USB Camera is all set and ready to GO.
3.3 Connecting to hangouts.google.com
1.Sign in to google. Hangouts with your Gmail ID and follow the instructions given in the figures below.
2. Choose the person you want to contact and a box will open on the left.

Now ensure that the microphone and webcam are setup and recognized correctly.
For this click on the lock symbol next to the URL and select “Allow”once more for camera and
microphone, though “Allow” already appears on the selection.
Start the video call and ensure Settings (small icon on right hand side) shows as follows

Hang up Video call when completed.
Each video calling application is likely to have some settings for microphone and webcam that are
externally attached peripherals. Please ensure that these settings have been made when using for the
first time.

5 FAQs
1 My TV, Monitor does not show any Display
Check for correct connections of the HDMI to the Display and make sure that the Right Display port is
configured in the TV where you have connected. Example- Select HDMI1 through the TV Remote if you have
connected the HDMI cable to the HDMI 1 port in the TV/Monitor.
2 Can I use a third party power charger as the power supply?
To ensure stability, use a power charger/supply that is rated with a minimum of 5V @ 2.5 A. Any power
supply with current capacity under 2.5 A may damage the file system and/or hardware.
3 Do I have to have an SSD drive?
No, an SSD drive is not necessary.
4 I need help to reload the Raspberry PI OS.
Before reloading, please backup all information onto a USB or external hard drive. Find help with
installing Raspberry Pi OS on your Raspberry Pi in our online Getting started guide.
5 I cannot connect to Internet/ Taskbar show 2 red X
Check the modem or Wi-Fi connection or LAN devices and turn them on, the above symbol indicates that no
network connection Is present. Turn Off Wi-Fi, wait 30 second and then refresh.
6 DO’s and DON’T’S.
1 Do not keep removing and re inserting the SD Card as it is loaded with the Operating System critical
for smooth functioning of the System and multiple insertions is likely to damage the Product.
2 Do a proper shutdown process when you have finished using the computer.by going to Main Start Icon and
using the Logout process. It will prompt options Shutdown, Reboot and Logout. Disconnect the Plug from the
Mains post shutdown.
Do unplug the cables from the TV/monitor and power source & NOT from the Raspberry ports.
Note: Always ensure your software is up to date by connecting your eZeePC to the internet, opening the
Terminal and running the following commands:
$ sudo apt-get update
$ sudo apt-get upgrade
Prior to connecting new peripherals, it is advisable to run these commands once. This will ensure smooth
recognition of hardware and availability or related drivers.
You can also run these commands from the Raspberry Start Menu itself from Preferences. figure below
