Medical Equipment (Caution):
Care should be taken when using radio next to certain medical devices such as pacemakers. Keep a distance of at least 20
cm between the radio and these medical devices; do not put the radio in your chest pocket. Hold BBGR to the ear at the
opposite side of the body where the pacemaker is implanted to reduce potential interference. If necessary, please turn off
the radio. If you have any other question, please consult the medical equipment manufacture before using. Some digital
radios may interfere with certain hearing aids. If these disturbances occur, contact the hearing aid manufacture for a
solution. If you have any other medical equipment (such as implanted cochlea), consult with the manufacturer to ensure
that these devices can shield the surrounding RF signals.
In places with special requirements such as hospitals or recuperation, please pay attention to the restrictions on the use of
radios. If necessary, please turn off the radio.
