circumstances throw them into fire. Do not mix battery types (old and new or carbon and alkaline,
etc.). Remove the batteries when the device is not to be used for a long time. Improper use may
cause explosions and danger to life.
RF Interface
Turn the device off when onboard an aircraft, in a hospital, in an operating theatre or in the vicinity
of medical electronic equipment. The RF signals may interfere with the functionality of sensitive
devices. Keep the device at least 20cm (8 inches) away from pacemakers, as the RF signals may
interfere with the functionality of the pacemaker. The transmitted RF signals can cause interference
with hearing aids. Do not place the device with the wireless adapter turned on near flammable
gases or in a potentially explosive area (e.g. a paint shop), as the transmitted RF signals may cause
explosions or fire. The range of the radio wave signals depends on environmental conditions.
