Antenna: built-in antenna (cannot be removed)
Control system, regulation, and switches: The user cannot
control, regulate, or switch over the radio transmission function
of the antenna.
(2) The unauthorized modification of usage scenarios or the
conditions of use, expansion of the transmission frequency
range, or increase of the transmission power (including installing
additional transmission power amplifiers), as well as the
unauthorized modification of the transmission antenna are not
allowed;
(3) The product may not interfere in any way with any legal radio
transmitters (stations) and may not offer any shielding from
harmful interference;
(4) The product must be able to tolerate interference caused by
industrial, scientific, and medical (ISM) devices which radiate
high frequency energy or other legal interference from radio
transmitters (stations);
(5) Should the product cause harmful interference on other legal
radio transmitters (stations), product use must be discontinued
immediately and suitable measures must be taken prior to using
the product again in order to eliminate said interference;
(6) When using micropower devices inside of an aircraft or
radiometric observatories, or when using such devices in
meteorological radar stations, satellite ground stations (including
measuring and control stations, distance measuring stations,
receiving stations, or navigation stations), as well as in radio
