Electromagnetic Interference / Electromagnetic Compatibility
Remark: Electromagnetic Interference (EMI) occurs in nearly every electronic equipment, by not enough shielding, improper design or
incorrect electromagnetic compatibility configuration. Not allowed to change the transmitting frequency, to increase the
transmission power (including the installation of additional RF power amplifier).
Not allowed to use an external antenna or other transmitting antenna.
Shall not cause harmful interference to a variety of legitimate radio services while using, if found harmful interference, should
immediately stop using, and to take measures to eliminate the interference before continuing.
Prohibition of interconnection with the public telephone network, public mobile communication network and other telecommunication
networks.
Place
To avoid electromagnetic interference and other problems caused by electromagnetic incompatibility, please turn off the transceiver
in the place where there is a sign showing “No transceiver". Hospitals or medical institutions may use external RF energy very
sensitive equipment. Prohibit the use of airports and aircraft radio.
Medical devices
Pacemaker
Advanced Medical Technology Association of the United States proposes holding the handheld transceiver with pacemakers should
be kept the distance of at least 6 inches (15cm). These proposals are consistent with the provisions by the U.S. Food and Drug
Administration.
With pacemakers should observe the following items:
When the transceiver is turned on, the distance between the pacemaker and the transceiver at least 6 inches (15cm);
Do not put the transceiver in a breast pocket; Please use the pacemaker the other side of the ear to listen, to
minimize potential interference;
If you suspect transceiver interference with the pacemaker, immediately turn off it.
Hearing Aids
Some transceivers may interfere with some hearing aids. When there is such interference, you can consult the hearing aid
manufacturer to discuss alternatives.
Other Medical Equipments
If you use other personal medical device, consult the device manufacturer to determine whether these devices can effectively
shield radio frequency energy. Your doctor can provide you with such help.
Safe Driving
Check your car seat using the transceiver the relevant laws and regulations, and follow the regulations.
