Cisco recommends the use of good quality external devices (speakers, microphones, and headsets)
that are shielded (screened) against unwanted radio frequency (RF) and audio frequency (AF)
signals.
Depending on the quality of these devices and the proximity to other devices such as mobile phones
or two-way radios, some audio noise may still occur. In these cases, Cisco recommends that you
take one or more of the following actions:
Move the external device away from the source of the RF or AF signals.
–
Route the external device cables away from the source of the RF or AF signals.
–
Use shielded cables for the external device, or use cables with a better shield and connector.
–
Shorten the length of the external device cable.
–
Apply ferrites or other such devices on the cables for the external device.
