Cleaning the unit
When the outside of the unit is dirty, clean it by wiping with a soft dry cloth. If the unit is particularly dirty, soak a cloth
in a dilute solution of neutral detergent, and wring it well before wiping. Do not use solvents such as thinner,
benzene, or alcohol, as they may damage the surface.
Do not use the headset near medical devices
Radio waves can affect cardiac pacemakers and medical devices. Do not use the headset in crowded places such as
crowded trains or inside a medical institution.
Because the headset uses magnets, it can affect medical devices such as cardiac pacemakers, defibrillators, and
variable-pressure shunts for hydrocephalus. Keep the headset away from these devices and people using these
devices. If you are using these devices and concerned about using the headset, please consult your doctor before
use.
Keep the headset away from the magnetic card
The headset uses magnets. If you bring a magnetic card close to the magnet, the card magnet may be affected and
become unusable.
