IMPORTANT:
DEMONSTRATION
CONDENSATION
When the power cord is plugged into an AC household outlet or the unit is loaded with the
batteries, Demonstration Mode starts. To cancel the Demonstration mode, press the
POWER button or hold the BBS button pressed for more than 3 seconds.
When the unit is moved to a location where the temperature is around 0 degrees C to a
warm location, the unit may not function properly. It is due to condensation generated
inside the unit. Leave the unit for about one hour to let it dry before normal operation.
