Usage Precautions
Interference with other electrical equipment
In consideration of safety, the F has been
designed to minimize its emission of electro-
magnetic waves and to suppress interference
from external electromagnetic waves. How-
ever, equipment that is very susceptible to
interference or that emits powerful electro-
magnetic waves could result in interference if
placed nearby. If this occurs, place the F
and the other device farther apart.
With any type of electronic device that uses
digital control, including the F, electro-
magnetic interference could cause malfunc-
tion, corrupt or destroy data and result in other
unexpected trouble. Always use caution.
Cleaning
Use a soft cloth to clean the exterior of the unit
if it becomes dirty. If necessary, use a damp
cloth that has been wrung out well to wipe it.
Never use abrasive cleansers, wax or solvents
such as alcohol, benzene or paint thinner.
Breakdown and malfunction
If the unit becomes broken or malfunctions,
immediately turn the power off, disconnect the
external power supply, remove the batteries
and disconnect other cables. Contact the store
where you bought the unit or ZOOM service
with the following information: product model,
serial number and specific symptoms of break-
down or malfunction, along with your name,
address and telephone number.
