NOTE: The Emissions characteristics of this equipment make it suitable
for use in industrial areas and hospitals (CISPR 11 class A). If it is used in
a residential environment (for which CISPR 11 class B is normally
required) this equipment might not offer adequate protection to
radio-frequency communication services. The user might need to take
mitigation measures, such as relocating or re-orienting the equipment.
