Care

• Whenever caring, make sure to first unplug the AC adaptor from the electrical outlet. Also remove the instrument’s batteries if battery power is being used.

Location

•Never locate the instrument in areas subject to high humidity or heavy accumula- tion of dust. Doing so may cause fire or electrical shock.
