Working product. The sound of the light bulb and the switch being pressed also works. Original belt. It seems to be in not bad condition for an old item. No warranty due to it being a vintage item. This is the "Walking Dictionary Casio English-Japanese/Japanese-English Digital" 'T-1500' released in February 1982. Positioned as a learning tool, it contains a total of 1,666 English words and idioms with their Japanese translations, as well as 80 sets of irregular verb conjugations and example sentences. Thank you.
