Equipped with a queuing lever that can be used for heading out.

The winding speed is adjustable in 3 stages.

Equipped with an absence recording function, it is possible to record absence by combining with an electronic digital clock.

Recording techniques such as echo and multi-play are available.

Built-in 30W + 30W amplifier as HiFi amplifier.

Equipped with a tape tension comparator and reel size selector, stable tape tension is achieved.

It is compatible with tape number 10.
