Hi,
1. According to EN 301 489-1 the definition of ancillary equipment is:
"equipment (apparatus), used in connection with a receiver or transmitter
NOTE: It is considered as an ancillary equipment (apparatus) if:
the equipment is intended for use in conjunction with a receiver
or transmitter to provide additional operational and/or control features to the
radio equipment, (e.g. to extend control to another position or location); and
the equipment cannot be used on a stand alone basis to provide
user functions independently of a receiver or transmitter; and
the receiver or transmitter, to which it is connected, is capable of providing
some intended operation such as transmitting and/or receiving without the
ancillary equipment (i.e. it is not a sub-unit of the main equipment essential
to the main equipment basic functions).
2. According to the above, it is my understanding that any ancillary
equipment would have to meet all three conditions as the word "and" is used at
the end of the first two conditions.
3. Questions:
3.1. If a radio device uses an external power supply (e.g. AC/DC adapter)
without which it cannot function, would the power supply be considered
ancillary equipment? My opinion is no but I would like to hear other opinions.
3.2. A radio device uses an external power supply (e.g. AC/DC adapter) to
charge an internal re-chargeable battery. The device can also operate from the
battery power without the power supply. Would the power supply be considered
ancillary equipment in this case? My opinion is yes as the device can operate
without the power supply once the battery is charged but I would like to hear
other opinions.
4. The above is due to disagreement with customer concerning radiated
emission testing of the power supply as ancillary equipment as stand alone for
a device with a re-chargeable battery
5. Thanks in advance for any opinions.
