Beware of condensation
When water vapor comes into contact with the surface of cold material, water drops are produced. If condensation occurs, correct operation may not be possible, or the unit may not function correctly. This is not a malfunction, however, and the unit should be dried. (To do this, turn the POWER switch ON and leave the unit as it is for several hours.) Be especially careful in the following conditions: � When the unit is brought from a cold place to warm place, and there is a large temperature difference. � When a heater starts operating. � When the unit is brought from an air-conditioned place to a place of high temperature with high humidity. � When there is a large difference between the internal temperature of the unit and the ambient temperature, or in conditions where condensation occurs easily.

Resetting the unit
This system uses a microcomputer so it may malfunction due to external noise or interference. In such a case, unplug the power cord and remove the batteries, then plug the power cord again and insert the batteries again.
