A personal communication device, such as a mobile phone, pager, palm computer is provided with a facility for transmitting a signal to a remote alerting device, such that silent alerting can take place without the need to carry the communication device. The device 1 is associated with remote alarm (not shown) which may be detachably mounted on the device 1. This senses a silent alert on the device 1 and relays a coded ID signal to a remote alerting device via a radio, optical or infrared link. The remote alert may be incorporated in a wearable accessory, such as glasses, watch, ring or other jewellery. The alert device may be able to transmit back to the communication device 1 to control the call or the remote alarm. |
