sunlight, high humidity, near water or other liquids, or high
temperature.
2. Make sure the voltage matches the power supplied in the area.
3. Do not insert or drop metal, flammable or other foreign objects into
the machine through the ventilation slits, as this may cause fire or
electric shock.

keyboard is disabled however the ECR's power is still ON. Make sure
the AC adapter cord is disconnected before opening the upper shell
