Battery Life

The average battery life of the Blue2 is about 13 hours with general use. Proper management is required to ensure the health of the Lithium-Ion battery used within this product. Here are suggestions to prolonging the life of your product’s internal battery;

1. Keep your device and its battery at room temperature
2. Avoid completely discharging the device’s battery
3. When storing the device for extended periods, charge the battery to about 60% and then put it in a cool, dry place

Switch Options (Internal and External)
The Blue2 has two built-in switches, one white and one orange. These switches can be used to active two independent functions in any of the six available modes. You may also opt to connect an alternative switch to the Blue2. This can be done by using either (or both) of the 3.5mm connections on the back. Please note that any switch connected to the Blue2 will emulate the same function as the built-in switches. They cannot be assigned independent functions.

Pairing Details

The Blue2 can be paired with any Bluetooth-enabled iOS, Android, Mac, Windows, or Chrome device. Functionality may be limited depending on the device you are pairing with the Blue2. The Blue2 is designed to be seen by other devices like a Bluetooth keyboard, therefore the information that is transmitted from the Blue2 to a device is a keyboard keystroke. For example, Mode 1 of the Blue2 sends a "space bar" when pressing the white switch (labeled S1) and "enter key" for the orange switch (labeled S2).

Pairing to a device

1. Turn Blue2 on using the on/off switch. 
2. Press the pairing button on Blue2 one time. 
3. In your devices Bluetooth settings find and select BLUE2. 
4. Repeatedly tap the mode button on Blue2 to select a mode.
5. Set up any settings for your choosen method of switch access within the app or through accessibility options for the device you paired with Blue2.
6. Blue2 is now ready for use with your device and/ or app.

Configuring Blue2 with iOS & MacOS Switch Control

Blue2 can be paired to any iOS or MacOS device to be used for the accessibility option called Switch Control. Switch Control is a powerful accessibility option that allows users to quickly and effectively navigate their iOS or MacOS device by use of our Blue2. For further information please review AbleNet's iOS 11 User Guide.

Configuring Blue2 with Android Accessibility

Blue2 can be paired to many Android devices to be used for Android Accessibility options. To fully utilize these features you must use a device that has Adroid operating system 5.0 or higher. Here are three links for more details on Android Accessibility.

Configure Blue2 with an App

There are many applications in the marketplace for Blue2 supported hardware. We recommend finding an application that works with keyboard keystrokes (see "Pairing Details"). Most apps that are built with accessibility in mind are intuitive in terms of setup, but if you find an app you like, we recommend accessing the user's manual for accessibility features and options.

ComTroubleshooting Blue2

Issue 1: Blue2 states "Connection Unsuccessful - Make sure "Blue2" is turned on and in range." (iOS device-specific error message).
Common reasons this may occur:

• Blue2 is not turned on.
• Blue2 is not close enough to the paired device.
• Blue2 is already paired to a device but you are trying to pair it to an alternative device. The Blue2 can only be paired to one device at any time.
• Blue2 was paired correctly with a device and functional but is now not working and shows as "Not Connected". This most likely is an issue with the amount of power the Blue2 currently has available.

Possible Resolution:

• Check that the Blue2 power switch is in the "on" position.
• Make sure the Blue2 is within 30 feet of the iPad.
• Un-pair the Blue2 from the first device. Press and hold the "Pair" button on the side of the Blue2 until the "S2" lights up near the center. Release the button and the Blue2 should be in the list as a pair-able device.
• Charge the Blue2 for at least 1 hour, then attempt to reconnect your device. To charge, plug the device into the charger. You will see lights near the center of the device flashing, indicating the device is charging. When fully charged the lights stop flashing.

Issue 2: Blue2 shows as "Connected" in my devices settings, but it is not functional.
Common reasons this may occur:

• When power of the Blue2 is low it is possible to experience intermittent connectivity. You may see the device as being paired but not receive any output when pressing switches.
• Check that the “Learn” switch is not active, as this causes all communication to pause. If you press “Mode Selection” multiple times, found on the right side of the Blue2, and only Modes 4-6 are available for selection the switch is active.

Possible Resolutions:

• Charge the Blue2 for at least 1 hour, then attempt to reconnect your device. To charge, plug the device into the charger. You will see lights near the center of the device flashing, indicating the device is charging. When fully charged the lights stop flashing.
• Turn the "Learn" Switch off, then attempt to use the Blue2 with your device.

Issue 3: S1 and S2 light are constantly lit solid yellow and red.
Common reasons this may occur:
When turning on Blue2 you may have held down the pairing button. This activates “Engineering” mode and locks the Blue2’s Bluetooth signals needed for communication to a device.

Possible Resolution:
Turn off the Blue2, wait 5 seconds, then turn it back on without pressing and holding the Pairing button. This should restore all primary functions of the Blue2.

Issue 4: Unable to select Mode 1, 2 or 3.
Common reasons this may occur:
Check that the “Learn” switch, located ont he right side, is not active. It is only necessary to activate when programming custom keyboard keystrokes into Blue2. When the switch is activated the Bluetooth communication is locked out. If you press “Mode Selection” (found on the right side of the Blue2) multiple times and only Modes 4-6 are available for selection the switch is active.

Solution: Turn the "Learn" Switch off, then cycle between all of the modes normally
