Q. How many hours does TD-01 Portable work by battery power?

By using specified Alkaline battery, TD-01 Portable works around 24 hours continuously.
Other type battery can be used as well.

Q. How many hold value can be stored?

Up to 300 hold data can be stored in TD-01Portable

Q. How many waveforms can be stored?

Yes, you can connect equipped USB cable to USB port to supply power.

Q. Can I change the languages?

Yes, you can. You can select English or Japanese.

Q. What is the wire breaking detection?

Estimated wire breaking part is shown as RED color.
It doesn't show estimated part, if wire breaking part are

Q. What is the static strain function?

Static strain means that strain value when transducer gets no forces. It's called initial strain value as well and if this value is too big, transducer was damaged by overload.
So by checking static strain value, defect of transducer can be detected.

Q. Can I operate by dirty , wet hand?

For this purpose, soft case is available and it protect dust and dripping

Q. Is carrying case available?
