Microphone Mini DM-05
Radio Range and Channels
The transmitter and receiver have built-in antennas. The
radio range between the units is around 30 metres. This
may however vary depending on the particular environ-
ment you are in. Like all radio systems, Comfort Digisys-
tem communicates on specific channels. If you use two
transmitters on the same channel or a neighbouring one,
there may be interference. Other electronic equipment
can also interfere with radio transmissions.
In most European countries, channels 1-3 (863.250 -
864.750 MHz) may be used for hearing products. How-
ever, you should always check with the frequency assign-
ment authority in your own country which channels are
free and which require a licence.
