I'm experiencing interference to my landline phone, what can be done?
Problems with radio transmissions coming across landline telephones (i.e. other than cordless) are due to deficiencies or faults in the telephone. As these are design or installation problems, you should approach your equipment supplier for further assistance.
Interference to cordless phones – cordless phones operate under a General User Radio Licence which means that they operate on shared frequencies and are not protected from interference.
Replacing the cordless phone with one operating on another frequency or band may resolve the problem.
I'm experiencing interference to my PC, what can be done?
Interference to computers from radio transmissions is unusual and may be the result of a signal pick-up on power leads, speaker leads or other attached cables. Radio frequency filtering may assist with this problem. As this is a design or installation issue, you should contact the equipment supplier for further assistance.
