Lets take a tour of the features and tools of your SpringBoard Lite.

What is on your Front Panel of the SpringBoard Lite:
BATTERY LOW: When this light flashes, the batteries need to be charged. Plug in the battery charger.
BATTERY CHARGING: When you plug in the charger, the "Charging" light flashes. A rapid flash indicates fast-charging; a slow flash indicates that the battery is charged but it will continue to trickle-charge as long as the charger is plugged in.
ON/OFF: Turns the device ON or OFF. If you turn the device off with this button, you must use it to turn the device back on.
TOOLBOX: Takes you to the Toolbox where you can use the system menus.
CHOOSE ACTIVITY: Use this to select different Activities. This key is set up as a default setting from the factory and can be changed if desired.
SET-UP: Use this key for setting up Pages, Activities and storing vocabulary. After you select the SET-UP key, select the key on your overlay you want to change and follow the prompts on your touchscreen. This key is set up as a default setting from the factory and can be changed if desired
RECORDING MICROPHONE: This is the small round hole to the right of the SET-UP key. When you record messages, speak toward this area.
Features on the top of the device:

Infrared Windows: Use these windows to teach remote control commands to the SpringBoard Lite and then to send the commands to your remote controlled devices.
To teach remote control signals to your SpringBoard Lite, point a remote control at the window on the right as you look at the top of the case (as in the picture above).
When you send the signals from the SpringBoard Lite to a TV or other remote controlled appliances, the window on the left must be facing in the general direction of the object you want to control.
Handle
Use the built-in handle to carry your SpringBoard Lite.

Battery Door: The device batteries are underneath this door. There is also a card slot at the top of the battery door that holds the system software card. Should you need to, you can remove the battery door by unscrewing it from the case.
Reset Button (see the arrow in the above graphic): If your SBL stops working for some reason, push the re-set button to see if that solves the problem. Unbend a paper clip and poke it into the hole to press the re-set button.
Wire Table Stand: The optional wire table stand allows the SBL to sit on a table in a more vertical position, rather than flat on a surface.
Wheelchair Mounting Plate: The optional wheelchair mounting plate allows the SBL to be attached to a wheelchair mount.
