NOTE 1: The life of the head maybe shortened when the unit is used in a place where there is high temperature, humidity, or dust. Therefore, use the unit in an air conditioned room and not in dusty areas. It is recommended to store the tape at normal temperature and humidity.

NOTE 2: When the drum assembly is replaced the upper drum assembly is also replaced.
