2. No change of emission frequency or increase of emission power (including the addition of
RF power amplifier) without permission is allowed, no use of external antenna or switch
to another emission antenna without permission is allowed;
3. No harmful interference to various lawful radio communication services shall be produced
during the use; once interference is found, the use shall be stopped immediately and shall
not be resumed before measures are taken and the interference is eliminated;
4. For the use of micro power radio devices, the interference of various radio services or the
radiated interference of devices for industrial, scientific, and medical use must be
tolerated.
5. Use near an aircraft or airport is forbidden.
