Electromagnetic Environment Guidance
The EMISSIONS characteristics of the freezer make it suitable for use in commer-
cial, industrial or institutional occupancies (CISPR 11 class A). If it is used in a resi-
dential 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
reorienting the equipment.
