electromagnetic environment due to fixed RF transmitters, an electromagnetic site
survey should be considered. If the measured field strength in the location in which the
SwitchPoint Infinity® 3 Control System is used exceeds the applicable RF compliance
level above, the SwitchPoint Infinity® 3 Control System should be observed to verify
normal operation. If abnormal performance is observed, additional measures may be
necessary, such as re-orienting or relocating the SwitchPoint Infinity® 3 Control System.

Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/
m.

The SwitchPoint Infinity® 3 Control System is intended for use in an electromagnetic
environment in which radiated RF disturbances are controlled. The customer or the
user of the SwitchPoint Infinity® 3 Control System can help prevent electromagnetic
interference by maintaining a minimum distance between portable and mobile RF
communications equipment (transmitters) and the SwitchPoint Infinity® 3 Control
System as recommended below, according to the maximum output power of the
communications equipment.

For transmitters rated at a maximum output power not listed above, the recommended
separation distance (d) in meters (m) can be estimated using the equation applicable to
the frequency of the transmitter, where P is the maximum output power rating of the
transmitter in watts (W) according to the transmitter manufacturer.
