Carrying case for your adapter kit
The adapter has a cable extending from one end of the adapter that connects to
your notebook computer. The adapter has two connectors for the different
electrical source cables.
Using the adapter
The power adapter can be connected to an automobile power receptacle, a
4-pin in-flight power receptacle, or a standard AC electrical socket. During
operation, if the power adapter detects a fault, such as a short circuit or high
temperature, the power adapter will shut down automatically to prevent
damage.
Notes:
1. When the adapter shuts down due to a fault it will be latched off until the
fault is removed AND the adapter is disconnected from the power source
for at least 10 seconds.
2.
The adapter needs adequate ventilation for proper operation. It is normal
for the adapter to be warm to touch during use.
