Getting Started
Welcome to your new Chameleon 20™ Braille display.
This user guide provides instructions for orientation, usage, navigation,
and updating of the device. For more information please refer to the
Chameleon 20 product page on the APH website or call APH Customer
Service at 1(800) 223-1839.
In the Box
The box contains the following items:
• Chameleon 20™ braille display
• USB-C to USB-A cable
• USB to AC adapter
• Three thermoplastic polyurethane (TPU) bumper cases in
pomegranate, purple, and teal
• Nylon carrying case with lanyard
• Sheet of various bug stickers and logos
• Print and Braille Getting Started guides
Orientation of Chameleon 20
The Chameleon has a 20-cell braille display, a Perkins-style keyboard, two
Space bars, a Home button and four thumb keys for navigation.
Top Face
The top face of the Chameleon can be divided into two sections: front
and rear.
The front section of the top face consists of a refreshable braille display
containing 20 braille cells and 20 cursor routing buttons. Each cursor routing
button is associated with the braille cell directly below it. When editing text,
pressing one of the cursor routing buttons moves the editing cursor to the
associated braille cell.
When you are not editing text, any cursor button activates a selected item.

8
The rear section of the top face includes a Perkins-style braille keyboard
where each key represents a Dot on a braille cell. The keys under your left
hand represent Dots 1, 2, 3, and Backspace, where Dot 1 is located under
your index finger and Backspace under your little finger. The keys under
your right hand represent Dots 4, 5, 6, and Enter, where Dot 4 is located
under your index finger and Enter under your little finger.
Front Edge
On the front edge of the Chameleon are five buttons. From left to right, the
buttons are as follows:
• Previous thumb key
• Left thumb key
• Home button (circular shape) – used to return to the Main menu or exit
Terminal mode
• Right thumb key
• Next thumb key
Left Edge
On the left edge, from front to back are the following:
• USB-A port
• Power button – press and hold this button for 2 seconds to turn the
device ON.
• Green LED – visually indicates the status of the device
• USB-C port – use the cable that came with your Chameleon to connect
it to a power outlet or a PC.
Right Edge
On the right edge, from front to back are the following:
• Two volume buttons (Currently not active)
• 3.5m Audio jack (Currently not active)

9
Rear Edge
The rear edge only contains an SD card port located near the left edge of
the device. This port allows you to insert SD cards for external storage.
Bottom Side
In each corner underneath your Chameleon are four anti-slip pads.
In the middle, closer to the front edge is a slightly indented rectangle with
a different texture. In this rectangle is a sticker containing printed hardware
information about your Chameleon. Above the sticker, there is a braille label
containing the serial number of your device.
Towards the back left of the device is the battery compartment. It is closed
and secured with two Phillips-head screws.
Charging Chameleon 20
Prior to using your Chameleon, make sure it is charged completely.
Connect the USB-C end of the recharge cable to the USB-C port located on
the left edge of your Chameleon. Minimal effort is required and forcing the
connection can damage the cable or the device.
Connect the USB-A end of the recharge cable to the power adapter, then
plug the power adapter into a power outlet. Use the provided power adapter
for optimal recharge.
Alternatively, you can charge the device using your computer and the
USB-A to USB-C recharge cable, but note that this method of charging is
slower than charging with a power adaptor.
Powering On and Off
The Power button is on the left edge of the Chameleon. It is oval-shaped
with a raised Dot in the center.
If your device is charged, press and hold the Power button for approximately
2 seconds to power on the Chameleon. There is a quick vibration and

10
“starting” appears on the braille display along with a tactile loading
animation that circles during start-up.
After a few seconds, the start-up is complete and “editor” appears on the
braille display. Your Chameleon is now ready for use.
To power Off, press and hold the Power button for approximately 2 seconds.
A confirmation message appears on the braille display. Select Ok by
pressing the Previous or Next thumb key, then press Enter or a
Cursor-routing key.
Alternatively, you can follow these steps to power Off the Chameleon:
1. Press P to reach the Power Off menu item.
2. Press Enter or a cursor routing key.
3. Select Ok by pressing the Previous or Next thumb key.
4. Press Enter or a cursor routing key.
Adjusting the Sleep Mode
To preserve the battery, Chameleon goes into Sleep mode after 5 minutes
of inactivity. You can adjust the length of time in the settings. You can also
manually put your device into Sleep mode by a short press of the power button.
To wake up the device, press the Power button.
About the About Menu
The About menu provides various information about your device, such as
version numbers, model number, serial number, licenses, and copyright.
To open the About Menu:
1. Go to the Main menu.
2. Select Settings.
3. Press Enter.
4. Go to the About item.
5. Press Enter.
Alternatively, you can use the shortcut Space + I to open the About dialog.

Navigating and Using Menus
Navigating the Main Menu
The Main menu options are:
• Editor
• Terminal
• Library
• File manager
• Calculator
• Date and time
• Settings
• Online services
• User guide
• Power Off
Press the Previous or Next thumb keys to scroll through the list to the menu
item of your choice. Then press Enter or a cursor routing key to access it.
You can return to the main menu at all times by pressing the Home button or
Space with all six Dots.
Panning Text on the Braille Display
Often times the text on the braille display is too long to fit on a single line. To
read the entire sentence, scroll or “pan” the text ahead or back by pressing
the Left and Right thumb keys on the Chameleon. The Left and Right thumb
keys are the second and fourth buttons on the front edge of the device.
Using the Context Menu for Additional Functions
The Context menu is a special menu that is accessed from almost
everywhere in the device. It offers useful contextual functions that are
relevant to what you’re currently doing on your Chameleon. Think of it as the
Contextual menu of a PC. If you’re looking for a specific action, or simply
forgot the shortcut, chances are it can be found in the Context menu.

12
To activate the Context menu, press Space + M. The menu opens with a
list of actions you can perform at that particular moment. Scroll through the
menu to the desired action and press Enter or a cursor routing key.
Press Space + E to exit the Context menu.
Navigating by First Letters of Words
Most of the time, you can jump to an item in a menu by typing the first letter
of that item. Doing so automatically moves your focus to the first item in the
list starting with that letter. Typing the same letter twice moves the focus to
the second item in the list starting with that letter, and so on.
For example, to reach the Settings menu on the Chameleon, you type the
letter ‘S’ on your keyboard.
Using Shortcuts/Key Combinations to Navigate
As the name implies, shortcuts, also known as key combinations, make it
easy to quickly navigate through a menu or file.
The most commonly used shortcuts on the Chameleon 20 are indicated in
