Installing a Firmware Update

To install the new firmware on your Mantis or Chameleon, you can do so either over the air via a WIFI connection, or manually with a computer and thumb drive.

Downloading Over The Air:

The simplest way to update your Mantis or Chameleon is by connecting it to a personal WIFI connection. To do this, turn on your mantis so that it is at the device’s home menu:

Press space until you find “Settings” or just press S followed by enter.
In the Settings menu press space repeatedly to find “WIFI” or type a W followed by enter.
If you see that WIFI is set to “Off”, press enter to turn it on.
Now with WIFI turned on, press space repeatedly to find the “New Connection” option and press enter.
The first item you see is “Scan for SSID”, press enter here to scan for your network.
You will see a “Loading” prompt followed by a list of networks. Press space repeatedly to your network’s name and press enter.
When prompted for the network password, type it in and press enter.
You will see a “Loading” prompt followed by a “Connection Successful” message, confirming you are now connected to your network.
Shortly after connecting to your network you will receive a notification that a new update is available asking if you want to download and install. Press space to the Ok button and enter to start the process.
Downloading will take a short amount of time and your device will restart. Note that your battery must be above 50% to install the update, or connected to power.
Upon restarting, you will see the braille display represent a progress bar to show you the installation progress.
Upon completion your device will power off. Power it back on and you will be running the latest Mantis or Chameleon firmware.

If you prefer to install the firmware manually or are not able to use the over the air method via Wi-Fi, you can find the most recent braille reader firmware updates in the Manuals & Downloads section on the Mantis Q40 and Chameleon 20 product pages.
