Radio range
The transmitters are designed to
have a radio signal range of 80
meters under optimum conditions.
The following conditions may result
in a reduced range:
- Signal transmission through
building structures or vegetation
- Interference from TVs, computer
monitors and mobile phones.
Under certain circumstances, this
may prevent the receiver from
functioning at all.
- Positioning of the transmitter at
an unfavorable distance from sur-
faces which reflect radio waves,
for example floors and walls.
This may lead to the signal wave
being weakened or even cancel-
led out by the reflected wave.
- Metallic objects reduce the range
due to the shielding effect of the
metal.
- Particularly in towns and cities,
there may be many other sources
of radio waves which can disrupt
the original signal.
- Having units operating at similar
frequencies located close to one
another may also result in mutual
interference.
