Cisco Cisco Aironet 1250 Series Access Point Guía De Instalación

The following information is for FCC compliance of Class B devices:

The equipment described in this manual generates and may radiate 
radio-frequency energy. If it is not installed in accordance with Cisco’s 
installation instructions, it may cause interference with radio and television 
reception. This equipment has been tested and found to comply with the 
limits for a Class B digital device in accordance with the specifications in part 
15 of the FCC rules. These specifications are designed to provide reasonable 
protection against such interference in a residential installation. However, 
there is no guarantee that interference will not occur in a particular 
installation. 

Modifying the equipment without Cisco’s written authorization may result in 
the equipment no longer complying with FCC requirements for Class A or 
Class B digital devices. In that event, your right to use the equipment may be 
limited by FCC regulations, and you may be required to correct any 
interference to radio or television communications at your own expense.

You can determine whether your equipment is causing interference by turning 
it off. If the interference stops, it was probably caused by the Cisco equipment 
or one of its peripheral devices. If the equipment causes interference to radio 
or television reception, try to correct the interference by using one or more of 
the following measures:

Turn the television or radio antenna until the interference stops.
