Microphone DM05
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 environment you are in. Like all radio systems, Comfort
Digisystem 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. However, you should always check with the
frequency assignment authority in your own country which channels are free
and which require a licence.
