Use only the lithium-ion battery that Research In Motion (RIM) specifies for use with your particular BlackBerry Smart Card Reader model. RIM specifies lithium-ion batteries for use in BlackBerry devices in compliance with IEEE Std 1725-200x™. Using any other lithium-ion battery might invalidate any warranty provided with the BlackBerry Smart Card Reader and might present a risk of fire or explosion.
When the "nO bAtt" indicator appears on your BlackBerry Smart Card Reader, the lithium-ion battery is not inserted or an invalid lithium-ion battery is inserted. If you have inserted an invalid lithium-ion battery, remove it immediately and insert the lithium-ion battery that RIM specifies for use with your particular BlackBerry Smart Card Reader model. If you have inserted the lithium-ion battery that is specified for use with your particular BlackBerry Smart Card Reader model, remove and reinsert the lithium- ion battery. Verify that the battery connectors align with the connectors on your BlackBerry Smart Card Reader.
