Operating Instructions
The VC421, as delivered ex works, can be connected to different switches, timers

• Please note that radio sets cannot be operated in areas with increased risk of
interference (e.g. hospitals, airports).
• The remote control is only permitted for equipment and systems with which a
malfunction in the hand-held transmitter or receiver does not present a risk to
persons, animals or objects, or this risk is covered by other safety devices.
• The operator does not enjoy any protection from disturbances by other remote
signalling equipment and terminal equipment (for example, also by radio sets
operated in the same frequency range in accordance with regulations).
• Use radio receivers in conjunction only with devices and systems permitted by
the manufacturer.
Note
Ensure that the controls are not installed and operated in the vicinity of
metal surfaces or magnetic fields.
Radio sets transmitting at the same frequency could interfere with recep-
tion.
It should be noted that the range of the radio signal is restricted by legis-
lation and constructional measures.
