Charge LED has gone out before opening the door of the ASD once the ASD power has been
turned off.

cover of the H9 ASD when the power is on.

representative for repair information.
• Do not place any objects inside of the H9 ASD.
• If the H9 ASD should emit smoke or an unusual odor or sound, turn the power off immediately.
• The heat sink and other components may become extremely hot to the touch. Allow the unit to cool
before coming in contact with these items.
• Remove power from the H9 ASD during extended periods of non-use.
• The system should be inspected periodically for damaged or improperly functioning parts,
cleanliness, and to ensure that the connectors are tightened securely.
