Potential Interference to Electronic Equipment

The digital technology used by modern mobile phone services supports more users, a greater range of services and improved privacy for conversations.

However, the on-off nature of digital signals may cause interference to some electronic devices. The potential for interference decreases rapidly as the distance between the mobile phone and the electronic device increases. Higher frequencies of operation and lower transmit powers also tend to reduce interference.

Newer electronic devices usually offer better immunity against such interference.
