• Install in accordance with all national and local
electrical codes.
• Do not paint the RS232 interface.
• Operate in ambient temperatures of 32 - 104
°

• It is recommended that the transmitters (such as
the RS232) in a RadioTouch system should not be
placed more than 35 ft. (10.7 m) from the receivers
that each transmitter controls. The range and
performance of the RadioTouch system is highly
dependent on a variety of complex factors such
as:
- Distance between system components
- Construction of walls separating system
components
- Electrical equipment located near system
components
Location
Place the RS232 in a convenient and accessible
location.
