GENERAL NOTES ON RADIO OPERATION
The radio transmission is realised on a non-exclusive transmission path, which is
why interference cannot be ruled out. Further interference can be caused by
switching operations, electric motors or defective electrical appliances. The range
in buildings can deviate greatly from that in the free field. In addition to the trans-
mitting power and the receiving characteristics of the receiver, environmental
influences such as air humidity play an important role, as do the structural condi-
tions on site. The ODYON pro series is designed for ranges of several hundred
metres under optimal conditions. However, the maximum range is only achieved
with line-of-sight contact between transmitter and receiver and without high-fre-
quency interference.
Possible causes for reduced range are:
• Buildings of any kind or vegetation affect the range.
• The distance of the antenna to the body, as well as to other conductive surfaces
or objects.
• The "background noise" in non-rural areas can already be relatively high,
reducing the signal-to-noise ratio and thus the range.
• Similarly, it is not impossible that devices with similar operating frequencies
may be operating in the neighbourhood, making the receiver seemingly less
sensitive.
• If the receiver is in the vicinity of poorly shielded devices that produce
interfering radiation (e.g. PCs ), strong losses in range can also occur.
